+ +## 什么是正则表达式? + +> 正则表达式是一组由字母和符号组成的特殊文本, 它可以用来从文本中找出满足你想要的格式的句子. + + +一个正则表达式是在一个主体字符串中从左到右匹配字符串时的一种样式. +例如"Regular expression"是一个完整的句子, 但我们常使用缩写的术语"regex"或"regexp". +正则表达式可以用来替换文本中的字符串,验证形式,提取字符串等等. + +想象你正在写一个应用, 然后你想设定一个用户命名的规则, 让用户名包含字符,数字,下划线和连字符,以及限制字符的个数,好让名字看起来没那么丑. +我们使用以下正则表达式来验证一个用户名: + +

+

+ +以上的正则表达式可以接受 `john_doe`, `jo-hn_doe`, `john12_as`. +但不匹配`Jo`, 因为它包含了大写的字母而且太短了. + +目录 +================= + + * [1. 基本匹配](#1-基本匹配) + * [2. 元字符](#2-元字符) + * [2.1 点运算符 .](#21-点运算符-) + * [2.2 字符集](#22-字符集) + * [2.2.1 否定字符集](#221-否定字符集) + * [2.3 重复次数](#23-重复次数) + * [2.3.1 * 号](#231--号) + * [2.3.2 号](#232--号) + * [2.3.3 ? 号](#233--号) + * [2.4 {} 号](#24--号) + * [2.5 (...) 特征标群](#25--特征标群) + * [2.6 | 或运算符](#26--或运算符) + * [2.7 转码特殊字符](#27-转码特殊字符) + * [2.8 锚点](#28-锚点) + * [2.8.1 ^ 号](#281--号) + * [2.8.2 $ 号](#282--号) +* [3. 简写字符集](#3-简写字符集) +* [4. 前后关联约束(前后预查)](#4-前后关联约束前后预查) + * [4.1 ?=... 前置约束(存在)](#41--前置约束存在) + * [4.2 ?!... 前置约束-排除](#42--前置约束-排除) + * [4.3 ?<= ... 后置约束-存在](#43---后置约束-存在) + * [4.4 ?<!... 后置约束-排除](#44--后置约束-排除) +* [5. 标志](#5-标志) + * [5.1 忽略大小写 (Case Insensitive)](#51-忽略大小写-case-insensitive) + * [5.2 全局搜索 (Global search)](#52-全局搜索-global-search) + * [5.3 多行修饰符 (Multiline)](#53-多行修饰符-multiline) +* [额外补充](#额外补充) +* [贡献](#贡献) +* [许可证](#许可证) + +## 1. 基本匹配 + +正则表达式其实就是在执行搜索时的格式, 它由一些字母和数字组合而成. +例如: 一个正则表达式 `the`, 它表示一个规则: 由字母`t`开始,接着是`h`,再接着是`e`. + +
+"the" => The fat cat sat on the mat. 
+

+"The" => The fat cat sat on the mat.
+
+ +[在线练习](https://regex101.com/r/1paXsy/1) + +## 2. 元字符 + +正则表达式主要依赖于元字符. +元字符不代表他们本身的字面意思, 他们都有特殊的含义. 一些元字符写在方括号中的时候有一些特殊的意思. 以下是一些元字符的介绍: + +|元字符|描述| +|:----:|----| +|.|句号匹配任意单个字符除了换行符.| +|[ ]|字符种类. 匹配方括号内的任意字符.| +|[^ ]|否定的字符种类. 匹配除了方括号里的任意字符| +|*|匹配>=0个重复的在*号之前的字符.| +|+|匹配>1个重复的+号前的字符. +|?|标记?之前的字符为可选.| +|{n,m}|匹配num个中括号之前的字符 (n <= num <= m).| +|(xyz)|字符集, 匹配与 xyz 完全相等的字符串.| +|||或运算符,匹配符号前或后的字符.| +|\|转义字符,用于匹配一些保留的字符 [ ] ( ) { } . * + ? ^ $ \ || +|^|从开始行开始匹配.| +|$|从末端开始匹配.| + +## 2.1 点运算符 `.` + +`.`是元字符中最简单的例子. +`.`匹配任意单个字符, 但不匹配换行符. +例如, 表达式`.ar`匹配一个任意字符后面跟着是`a`和`r`的字符串. + +
+".ar" => The car parked in the garage.
+
+ +[在线练习](https://regex101.com/r/xc9GkU/1) + +## 2.2 字符集 + +字符集也叫做字符类. +方括号用来指定一个字符集. +在方括号中使用连字符来指定字符集的范围. +在方括号中的字符集不关心顺序. +例如, 表达式`[Tt]he` 匹配 `the` 和 `The`. + +
+"[Tt]he" => The car parked in the garage.
+
+ +[在线练习](https://regex101.com/r/2ITLQ4/1) + +方括号的句号就表示句号. +表达式 `ar[.]` 匹配 `ar.`字符串 + +
+"ar[.]" => A garage is a good place to park a car.
+
+ +[在线练习](https://regex101.com/r/wL3xtE/1) + +### 2.2.1 否定字符集 + +一般来说 `^` 表示一个字符串的开头, 但它用在一个方括号的开头的时候, 它表示这个字符集是否定的. +例如, 表达式`[^c]ar` 匹配一个后面跟着`ar`的除了`c`的任意字符. + +
+"[^c]ar" => The car parked in the garage.
+
+ +[在线练习](https://regex101.com/r/nNNlq3/1) + +## 2.3 重复次数 + +后面跟着元字符 `+`, `*` or `?` 的, 用来指定匹配子模式的次数. +这些元字符在不同的情况下有着不同的意思. + +### 2.3.1 `*` 号 + +`*`号匹配 在`*`之前的字符出现`大于等于0`次. +例如, 表达式 `a*` 匹配以0或更多个a开头的字符, 因为有0个这个条件, 其实也就匹配了所有的字符. 表达式`[a-z]*` 匹配一个行中所有以小写字母开头的字符串. + +
+"[a-z]*" => The car parked in the garage #21.
+
+ +[在线练习](https://regex101.com/r/7m8me5/1) + +`*`字符和`.`字符搭配可以匹配所有的字符`.*`. +`*`和表示匹配空格的符号`\s`连起来用, 如表达式`\s*cat\s*`匹配0或更多个空格开头和0或更多个空格结尾的cat字符串. + +
+"\s*cat\s*" => The fat cat sat on the concatenation.
+
+ +[在线练习](https://regex101.com/r/gGrwuz/1) + +### 2.3.2 `+` 号 + +`+`号匹配`+`号之前的字符出现 >=1 次个字符. +例如表达式`c.+t` 匹配以首字母`c`开头以`t`结尾,中间跟着任意个字符的字符串. + +
+"c.+t" => The fat cat sat on the mat.
+
+ +[在线练习](https://regex101.com/r/Dzf9Aa/1) + +### 2.3.3 `?` 号 + +在正则表达式中元字符 `?` 标记在符号前面的字符为可选, 即出现 0 或 1 次. +例如, 表达式 `[T]?he` 匹配字符串 `he` 和 `The`. + +
+"[T]he" => The car is parked in the garage.

+"[T]?he" => The car is parked in the garage.
+
+ +[在线练习](https://regex101.com/r/kPpO2x/1) + +## 2.4 `{}` 号 + +在正则表达式中 `{}` 是一个量词, 常用来一个或一组字符可以重复出现的次数. +例如, 表达式 `[0-9]{2,3}` 匹配 2~3 位 0~9 的数字. + + +
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+
+ +[在线练习](https://regex101.com/r/juM86s/1) + +我们可以省略第二个参数. +例如, `[0-9]{2,}` 匹配至少两位 0~9 的数字. + +如果逗号也省略掉则表示重复固定的次数. +例如, `[0-9]{3}` 匹配3位数字 + +
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.

+ +[在线练习](https://regex101.com/r/Sivu30/1) + +## 2.5 `(...)` 特征标群 + +特征标群是一组写在 `(...)` 中的子模式. 例如之前说的 `{}` 是用来表示前面一个字符出现指定次数. 但如果在 `{}` 前加入特征标群则表示整个标群内的字符重复 N 次. 例如, 表达式 `(ab)*` 匹配连续出现 0 或更多个 `ab`. + +我们还可以在 `()` 中用或字符 `|` 表示或. 例如, `(c|g|p)ar` 匹配 `car` 或 `gar` 或 `par`. + +
+"(c|g|p)ar" => The car is parked in the garage.
+
+ +[在线练习](https://regex101.com/r/tUxrBG/1) + +## 2.6 `|` 或运算符 + +或运算符就表示或, 用作判断条件. + +例如 `(T|t)he|car` 匹配 `(T|t)he` 或 `car`. + +

+
+ +[在线练习](https://regex101.com/r/fBXyX0/1) + +## 2.7 转码特殊字符 + +反斜线 `\` 在表达式中用于转码紧跟其后的字符. 用于指定 `{ } [ ] / \ + * . $ ^ | ?` 这些特殊字符. 如果想要匹配这些特殊字符则要在其前面加上反斜线 `\`. + +例如 `.` 是用来匹配除换行符外的所有字符的. 如果想要匹配句子中的 `.` 则要写成 `\.`. + +

+
+ +[在线练习](https://regex101.com/r/DOc5Nu/1) + +## 2.8 锚点 + +在正则表达式中, 想要匹配指定开头或结尾的字符串就要使用到锚点. `^` 指定开头, `$` 指定结尾. + +### 2.8.1 `^` 号 + +`^` 用来检查匹配的字符串是否在所匹配字符串的开头. + +例如, 在 `abc` 中使用表达式 `^a` 会得到结果 `a`. 但如果使用 `^b` 将匹配不到任何结果. 应为在字符串 `abc` 中并不是以 `b` 开头. + +例如, `^(T|t)he` 匹配以 `The` 或 `the` 开头的字符串. + +

+## What is Regular Expression?
+## Mi az a reguláris kifejezés?
+
+> Regular expression is a group of characters or symbols which is used to find a specific pattern from a text.
+> A reguláris kifejezés karakterek vagy szimbólumok egy csoportja, amelyet egy szövegből adott minták megtalálására használnak.
+
+A regular expression is a pattern that is matched against a subject string from
+left to right. The word "Regular expression" is a mouthful, you will usually
+find the term abbreviated as "regex" or "regexp". Regular expression is used for
+replacing a text within a string, validating form, extract a substring from a
+string based upon a pattern match, and so much more.
+
+A reguláris kifejezés egy olyan minta, amely illeszkedik egy adott karakterláncra
+balról jobbra. Maga a "Regular expression" kifejezést általában rövidítve lehet
+megtalálni, mint "regex" vagy "regexp". A reguláris kifejezést használják szövegrészek
+lecserélésére egy szövegben, űrlapok validálására, szövegrészek kiválasztására
+mintaegyezés alapján egy hosszabb szövegből és így tovább.
+
+Imagine you are writing an application and you want to set the rules for when a
+user chooses their username. We want to allow the username to contain letters,
+numbers, underscores and hyphens. We also want to limit the number of characters
+in username so it does not look ugly. We use the following regular expression to
+validate a username:
+
+Képzeld el, hogy egy alkalmazást írsz és szeretnél szabályokat állítani a felhasználónév
+kiválasztásához. A felhasználónév csak betűket, számokat, aláhúzásjelet és kötőjelet
+tartalmazhat. Szeretnénk limitálni a karakterek maximális számát is a felhasználónévben,
+hogy ne legyen csúnya. A felhasználónév validálására a következő reguláris kifejezést
+használjuk:
+
+


+

+  Regular expression
+  Regular expression
+

+
+Above regular expression can accept the strings `john_doe`, `jo-hn_doe` and
+`john12_as`. It does not match `Jo` because that string contains uppercase
+letter and also it is too short.
+
+A feljebbi reguláris kifejezés elfogadja a `john_doe`, `jo-hn_doe` és a
+`john12_as` karakterláncokat. Nem fog egyezni a `Jo`-ra mert ez nagybetűt
+tartalmaz és túl rövid is.

+## 1. Basic Matchers
+## 1. Bevezetés
+
+A regular expression is just a pattern of characters that we use to perform
+search in a text.  For example, the regular expression `the` means: the letter
+`t`, followed by the letter `h`, followed by the letter `e`.
+
+A reguláris kifejezés egy karakterminta, amit keresésre használunk egy
+szövegben. Például a `the` reguláris kifejezés a következőt jelenti: egy `t` betű,
+amit `h` követ, amit egy `e` követ.
+
+
+"the" => The fat cat sat on the mat.

+[Teszteld a reguláris kifejezést](https://regex101.com/r/dmRygT/1)
+
+The regular expression `123` matches the string `123`. The regular expression is
+matched against an input string by comparing each character in the regular
+expression to each character in the input string, one after another. Regular
+expressions are normally case-sensitive so the regular expression `The` would
+not match the string `the`.
+
+Az `123` reguláris kifejezés illeszkedik a `123` karakterláncra. A reguláris kifejezés
+minden egyes karaktere össze lesz hasonlítva a bevitt karakterlánc minden elemével
+egymás után. A reguláris kifejezések alap esetben kis-nagybetű érzékenyek, tehát a
+`The` reguláris kifejezés nem fog illeszkedni a `the` karakterláncra.
+
+
+"The" => The fat cat sat on the mat.

+## 2. Meta Characters
+## 2. Meta karakterek
+
+Meta characters are the building blocks of the regular expressions.  Meta
+characters do not stand for themselves but instead are interpreted in some
+special way. Some meta characters have a special meaning and are written inside
+square brackets. The meta characters are as follows:
+
+A meta karakterek a reguláris kifejezések építőkockái. A meta karakterek speciális
+módon értelmezendőek. Némelyik meta karakternek speciális jelentése van és
+szögletes zárójelek közé vannak téve. A meta karakterek a következők:
+
+|Meta character|Description|
+|:----:|----|
+|.|Period matches any single character except a line break.|
+|[ ]|Character class. Matches any character contained between the square brackets.|
+|[^ ]|Negated character class. Matches any character that is not contained between the square brackets|
+|*|Matches 0 or more repetitions of the preceding symbol.|
+|+|Matches 1 or more repetitions of the preceding symbol.|
+|?|Makes the preceding symbol optional.|
+|{n,m}|Braces. Matches at least "n" but not more than "m" repetitions of the preceding symbol.|
+|(xyz)|Character group. Matches the characters xyz in that exact order.|
+|||Alternation. Matches either the characters before or the characters after the symbol.|
+|\|Escapes the next character. This allows you to match reserved characters [ ] ( ) { } . * + ? ^ $ \ ||
+|^|Matches the beginning of the input.|
+|$|Matches the end of the input.|
+
+|Meta karakter|Leírás|
+|:----:|----|
+|.|A pont illeszkedik minden egyes karakterre kivéve a sortörést.|
+|[ ]|Karakter osztály. Minden karakterre illeszkedik ami a szögletes zárójelek közt van.|
+|[^ ]|Negált karakter osztály. Minden karakterre illeszkedik ami nincs a szögletes zárójelek közt.|
+|*|Illeszkedik az őt megelőző szimbólum 0 vagy több ismétlődésére.|
+|+|Illeszkedik az őt megelőző szimbólum 1 vagy több ismétlődésére.|
+|?|Opcionálissá teszi az őt megelőző szimbólumot.|
+|{n,m}|Kapcsos zárójelek. Illeszkedik az őt megelőző szimbólum minimum "n" de nem több mint "m" ismétlődésére.|
+|(xyz)|Karakter csoport. Illeszkedik az xyz karakterekre pontosan ilyen sorrendben.|
+|||Alternáció. Illeszkedik a szimbólum előtt és után álló karakterekre is.|
+|\|Escape-li a következő karaktert. A segítségével lefoglalt karakterekre is lehet illeszkedni [ ] ( ) { } . * + ? ^ $ \ ||
+|^|A bevitel elejére illeszkedik.|
+|$|A bevitel végére illeszkedik.|
+
+## 2.1 Full stop
+## 2.1 Full stop
+
+Full stop `.` is the simplest example of meta character. The meta character `.`
+matches any single character. It will not match return or newline characters.
+For example, the regular expression `.ar` means: any character, followed by the
+letter `a`, followed by the letter `r`.
+
+A full stop `.` a legegyszerűbb meta karakter példa. A `.` meta karakter illeszkedik
+minden egyes karakterre. Nem fog illeszkedni a kocsi vissza és a sortörés karakterekre.
+Például a `.ar` reguláris kifejezés jelentése: minden karakter, amit `a` aztán `r` követ.
+
+
+".ar" => The car parked in the garage.

+
+## 2.2 Character set
+## 2.2 Karakter osztályok
+
+Character sets are also called character class. Square brackets are used to
+specify character sets. Use a hyphen inside a character set to specify the
+characters' range. The order of the character range inside square brackets
+doesn't matter. For example, the regular expression `[Tt]he` means: an uppercase
+`T` or lowercase `t`, followed by the letter `h`, followed by the letter `e`.
+
+A szögletes zárójelekkel határozzuk meg a karakter osztályokat. A szögletes
+zárójelek közt kötőjel karakterrel határozhatunk meg karakter tartományokat.
+A karaktertartomány sorrendje nem számít. Például a `[Tt]he` reguláris kifejezés
+jelentése: nagybetűs `T` vagy kisbetűs `t` amit egy `h` majd egy `e` betű követ.
+
+
+"[Tt]he" => The car parked in the garage.

+
+A period inside a character set, however, means a literal period. The regular
+expression `ar[.]` means: a lowercase character `a`, followed by letter `r`,
+followed by a period `.` character.
+
+Egy pont a karakter osztályon belül egyébként szó szerint pont-ot jelent. A
+`ar[.]` reguláris kifejezés jelentése: kisbetűs `a` amit egy `r` aztán egy
+pont `.` karakter követ.
+
+
+"ar[.]" => A garage is a good place to park a car.

+
+### 2.2.1 Negated character set
+### 2.2.1 Negált karakter osztályok
+
+In general, the caret symbol represents the start of the string, but when it is
+typed after the opening square bracket it negates the character set. For
+example, the regular expression `[^c]ar` means: any character except `c`,
+followed by the character `a`, followed by the letter `r`.
+
+Általában a kalap szimbólum egy karakterlánc elejét jelenti, de ha egy nyitó
+szögletes zárójel után áll, akkor negálja a karakter osztályt. Például a 
+`[^c]ar` reguláris kifejezés jelentése: minden karakter a `c` kivételével
+ami után `a` aztán egy `r` betű áll.
+
+
+"[^c]ar" => The car parked in the garage.

+
+## 2.3 Repetitions
+## 2.3 Ismétlések
+
+Following meta characters `+`, `*` or `?` are used to specify how many times a
+subpattern can occur. These meta characters act differently in different
+situations.
+
+A következő meta karaktereket `+`, `*` vagy `?` arra használjuk, hogy meghatározzuk,
+hányszor fordulhat elő az al-minta. Ezek a meta karakterek máshogy viselkednek
+adott helyzetekben.
+
+### 2.3.1 The Star
+### 2.3.1 A csillag
+
+The symbol `*` matches zero or more repetitions of the preceding matcher. The
+regular expression `a*` means: zero or more repetitions of preceding lowercase
+character `a`. But if it appears after a character set or class then it finds
+the repetitions of the whole character set. For example, the regular expression
+`[a-z]*` means: any number of lowercase letters in a row.
+
+A `*` szimbólum az őt megelőző karakter nulla vagy több ismétlődésére illeszkedik.
+A `a*` reguláris kifejezés jelentése: nulla vagy több ismétlődése az őt megelőző `a`
+karakternek. De ha egy karakter osztály után áll akkor az egész karakterosztály
+ismétlődését keresi. Például, a `[a-z]*` reguláris kifejezés jelentése: bármennyi
+kisbetűs betű egy sorban.
+
+
+"[a-z]*" => The car parked in the garage #21.

+
+The `*` symbol can be used with the meta character `.` to match any string of
+characters `.*`. The `*` symbol can be used with the whitespace character `\s`
+to match a string of whitespace characters. For example, the expression
+`\s*cat\s*` means: zero or more spaces, followed by lowercase character `c`,
+followed by lowercase character `a`, followed by lowercase character `t`,
+followed by zero or more spaces.
+
+A `*` szimbólum használható a `.` meta karakterrel `.*`, ez illeszkedik
+bármilyen karakterláncra. A `*` szimbólum használható a whitespace karakterrel `\s`
+együtt, hogy illeszkedjen egy whitespace-ekből álló karakterláncra. Például a
+`\s*cat\s*`kifejezés jelentése: nulla vagy több szóköz, amit egy kisbetűs `c`,
+aztán egy kisbetűs `a`, aztán egy kisbetűs `t`, amit még nulla vagy több szóköz követ.

+
+### 2.3.2 The Plus
+### 2.3.2 A plusz
+
+The symbol `+` matches one or more repetitions of the preceding character. For
+example, the regular expression `c.+t` means: lowercase letter `c`, followed by
+at least one character, followed by the lowercase character `t`. It needs to be
+clarified that `t` is the last `t` in the sentence.
+
+A `+` szimbólum illeszkedik az őt megelőző karakter egy vagy több ismétlődésére.
+Például a `c.+t` kifejezés jelentése: kisbetűs `c` betű, amit legalább egy vagy
+több `t` követ. Itt tisztázni kell hogy a `t` az utolsó `t` a mondatban.

+### 2.3.3 The Question Mark
+### 2.3.3 A kérdőjel
+
+In regular expression the meta character `?` makes the preceding character
+optional. This symbol matches zero or one instance of the preceding character.
+For example, the regular expression `[T]?he` means: Optional the uppercase
+letter `T`, followed by the lowercase character `h`, followed by the lowercase
+character `e`.
+
+A reguláris kifejezésben a `?` meta karakter opcionálissá teszi az őt
+megelőző karaktert. Ez a szimbólum az őt megelőző karakter nulla vagy egy
+példányára illeszkedik. Például a `[T]?he` kifejezés jelentése: opcionális a
+nagybetűs `T`, amit egy kisbetűs `h`, majd egy kisbetűs `e` követ.

+## 2.4 Braces
+## 2.4 A kapcsos zárójelek
+
+In regular expression braces that are also called quantifiers are used to
+specify the number of times that a character or a group of characters can be
+repeated. For example, the regular expression `[0-9]{2,3}` means: Match at least
+2 digits but not more than 3 ( characters in the range of 0 to 9).
+
+A reguláris kifejezésben a kapcsos zárójeleket annak meghatározására használjuk,
+hogy egy karakter vagy egy karakter csoport hányszor ismétlődhet. Például a
+`[0-9]{2,3}` kifejezés jelentése: minimum 2 de nem több mint 3 karakter a `[0-9]`
+karaktertartományon belül.
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.

+
+We can leave out the second number. For example, the regular expression
+`[0-9]{2,}` means: Match 2 or more digits. If we also remove the comma the
+regular expression `[0-9]{3}` means: Match exactly 3 digits.
+
+Kihagyhatjuk a második számot. Például a `[0-9]{2,}` kifejezés jelentése:
+2 vagy több számra illeszkedik. Ha a vesszőt is kitöröljük `[0-9]{3}`: Pontosan
+3 számra illeszkedik.

+
+## 2.5 Character Group
+## 2.5 Karakter csoportok
+
+Character group is a group of sub-patterns that is written inside Parentheses `(...)`.
+As we discussed before that in regular expression if we put a quantifier after a
+character then it will repeat the preceding character. But if we put quantifier
+after a character group then it repeats the whole character group. For example,
+the regular expression `(ab)*` matches zero or more repetitions of the character
+"ab". We can also use the alternation `|` meta character inside character group.
+For example, the regular expression `(c|g|p)ar` means: lowercase character `c`,
+`g` or `p`, followed by character `a`, followed by character `r`.
+
+A karakter csoport al-minták csoportja amik zárójelek közé `(...)` vannak írva.
+Ahogy előbb már megbeszéltük, ha egy karakter után ismétlő karaktert rakunk, az
+ismételni fogja az előtte lévő karaktert. De ha egy ismétlő karaktert egy karakter
+csoport után rakunk, az ismételni fogja az egész csoportot. Például a `(ab)*`
+kifejezés illeszkedik nulla vagy több ismétlődésére az `ab` karaktereknek.
+Használhatunk alternáló meta karaktert `|` is a csoporton belül. Például a `(c|g|p)ar`
+kifejezés jelentése: kisbetűs `c`, `g` vagy `p` karakter, amit egy `a` aztán
+egy `r` karakter követ.
+
+

+
+## 2.6 Alternation
+## 2.6 Alternálás
+
+In regular expression Vertical bar `|` is used to define alternation.
+Alternation is like a condition between multiple expressions. Now, you may be
+thinking that character set and alternation works the same way. But the big
+difference between character set and alternation is that character set works on
+character level but alternation works on expression level. For example, the
+regular expression `(T|t)he|car` means: uppercase character `T` or lowercase
+`t`, followed by lowercase character `h`, followed by lowercase character `e` or
+lowercase character `c`, followed by lowercase character `a`, followed by
+lowercase character `r`.
+
+A reguláris kifejezésben a függőleges vonalat `|` alternálásra (választásra)
+használjuk. Az alternálás olyan, mint egy feltétel több kifejezés közt. Most
+azt gondolhatod, hogy a karakter osztály és az alternáció ugyan úgy működik.
+De a fő különbség köztük, hogy a karakter osztály a karakterek szintjén működik,
+az alternáció viszont a kifejezés szintjén. Például a `(T|t)he|car` kifejezés
+jelentése: nagybetűs `T` karakter vagy kisbetűs `t` karakter, amit egy `h` és
+egy `e` követ, VAGY kisbetűs `c` aztán `a` aztán `r` karakter.

+## 2.7 Escaping special character
+## 2.7 Speciális karakter escape-elése
+
+Backslash `\` is used in regular expression to escape the next character. This
+allows us to specify a symbol as a matching character including reserved
+characters `{ } [ ] / \ + * . $ ^ | ?`. To use a special character as a matching
+character prepend `\` before it.
+
+A visszaper `\` a reguláris kifejezésekben a következő karakter escape-elésére
+való. Ez enged nekünk szimbólumokat vagy lefoglalt karaktereket `{ } [ ] / \ + * . $ ^ | ?`
+megadni. Egy speciális karakter egyező karakterként való megadásához tedd elé
+a `\` karaktert.
+
+For example, the regular expression `.` is used to match any character except
+newline. Now to match `.` in an input string the regular expression
+`(f|c|m)at\.?` means: lowercase letter `f`, `c` or `m`, followed by lowercase
+character `a`, followed by lowercase letter `t`, followed by optional `.`
+character.
+
+Például a `.` kifejezést az összes karakter, kivéve a sortörés illeszkedéséhez
+használjuk. A `(f|c|m)at\.?` kifejezés jelentése: kisbetűs `f`, `c` vagy `m`, amit
+egy kisbetűs `a` aztán egy kisbetűs `t`, amit egy opcionális `.` karakter követ.

+## 2.8 Anchors
+## 2.8 Horgonyok
+
+In regular expressions, we use anchors to check if the matching symbol is the
+starting symbol or ending symbol of the input string. Anchors are of two types:
+First type is Caret `^` that check if the matching character is the start
+character of the input and the second type is Dollar `$` that checks if matching
+character is the last character of the input string.
+
+A reguláris kifejezésekben horgonyokat használunk, hogy megnézzük, az illeszkedő
+szimbólum a kezdő vagy a záró szimbóluma-e a karakterláncnak. A horgonyoknak két
+fajtájuk van: Az első a Kalap `^`, ami megnézi, hogy az egyező karakter a karakterlánc
+kezdő kerektere-e és a második a Dollár `$`, ami azt vizsgálja, hogy az egyező
+karakter a karakterlánc utolsó karaktere-e.
+
+### 2.8.1 Caret
+### 2.8.1 Kalap
+
+Caret `^` symbol is used to check if matching character is the first character
+of the input string. If we apply the following regular expression `^a` (if a is
+the starting symbol) to input string `abc` it matches `a`. But if we apply
+regular expression `^b` on above input string it does not match anything.
+Because in input string `abc` "b" is not the starting symbol. Let's take a look
+at another regular expression `^(T|t)he` which means: uppercase character `T` or
+lowercase character `t` is the start symbol of the input string, followed by
+lowercase character `h`, followed by lowercase character `e`.
+
+A kalap `^` szimbólumot arra használjuk, hogy megnézzük, hogy az egyező karakter
+a karakterlánc kezdő kerektere-e. Ha megadjuk a következő kifejezést: `^a`,
+akkor illeszkedik a `abc` karakterlánc `a` karakterére, mert az za első. De ha
+megadjuk, hogy: `^b`, ez nem fog illeszkedni az `abc` egyik részére sem, mert
+nem `b` a kezdő karakter. Nézzünk meg egy másik kifejezést. `^(T|t)he` jelentése:
+nagybetűs `T` vagy kisbetűs `t` a kezdő karaktere a karakterláncnak, amit kisbetűs
+`h`, majd kisbetűs `e` követ.

+lowercase character `a`, followed by lowercase character `t`, followed by a `.`
+character and the matcher must be end of the string.
+
+A dollár `$` szimbólumot arra használjuk, hogy megnézzük, hogy az egyező

+shorthand character sets are as follows:
+
+A gyakran használt karakter osztályokra a reguláris kifejezésnek vannak
+rövidítései, amikkel kényelmesebben tudunk használni általános kifejezéseket.
+A shorthand karakter osztályok a következők:
+
+|Shorthand|Description|
+|:----:|----|
+|.|Any character except new line|
+|\w|Matches alphanumeric characters: `[a-zA-Z0-9_]`|
+|\W|Matches non-alphanumeric characters: `[^\w]`|
+|\d|Matches digit: `[0-9]`|
+|\D|Matches non-digit: `[^\d]`|
+|\s|Matches whitespace character: `[\t\n\f\r\p{Z}]`|
+|\S|Matches non-whitespace character: `[^\s]`|
+
+|Rövidítés|Leírás|
+|:----:|----|
+|.|Minden karakter a sortörésen kívül.|
+|\w|Az alfanumerikus karakterekre illeszkedik: `[a-zA-Z0-9_]`|
+|\W|A nem alfanumerikus karakterekre illeszkedik: `[^\w]`|
+|\d|Számra illeszkedik: `[0-9]`|
+|\D|Nem számra illeszkedik: `[^\d]`|
+|\s|Whitespace karakterre illeszkedik: `[\t\n\f\r\p{Z}]`|
+|\S|Nem whitespace karakterre illeszkedik: `[^\s]`|

+## 4. Lookaround
+## 4. Lookaround
+
+Lookbehind and lookahead (also called lookaround) are specific types of
+***non-capturing groups*** (Used to match the pattern but not included in matching
+list). Lookaheads are used when we have the condition that this pattern is
+preceded or followed by another certain pattern. For example, we want to get all
+numbers that are preceded by `$` character from the following input string
+`$4.44 and $10.88`. We will use following regular expression `(?<=\$)[0-9\.]*`
+which means: get all the numbers which contain `.` character and  are preceded
+by `$` character. Following are the lookarounds that are used in regular
+expressions:
+
+A lookbehind (hátranézés) és a lookahead (előrenézés) speciális típusai a
+***nem tárolt csoport***oknak, amiket illeszkedésre használnak, de nincsenek
+benne az illeszkedési listában. Az előrenézést akkor használjuk, ha feltételezzük,
+hogy ezt a mintát egy másik minta előzi meg, vagy követi. Például kell nekünk
+az összes szám ami előtt `$` karakter áll a következő karakterláncból: `$4.44 and $10.88`.
+Ezt a mintát fogjuk használni: `(?<=\$)[0-9\.]*`, aminek a jelentése: Szedd ki az
+összes számot ami `.` karaktert tartalmaz és megelőzi egy `$` karakter. A
+következő lookaround-okat használhatjuk:
+
+|Symbol|Description|

+
+### 4.2 Negative Lookahead
+### 4.2 Negative Lookahead
+
+Negative lookahead is used when we need to get all matches from input string
+that are not followed by a pattern. Negative lookahead is defined same as we define
+positive lookahead but the only difference is instead of equal `=` character we
+use negation `!` character i.e. `(?!...)`. Let's take a look at the following
+regular expression `(T|t)he(?!\sfat)` which means: get all `The` or `the` words
+from input string that are not followed by the word `fat` precedes by a space
+character.
+
+A negatív előrenézést akkor használjuk, ha az olyan illeszkedések kellenek,
+amelyeket nem követ egy bizonyos minta. A negatív előrenézést ugyanúgy
+definiáljuk mint a pozitív előrenézést, az egyetlen különbség, hogy az
+egyenlőségjel `=` helyett negálást `!` használunk: `(?!...)`. Nézzük meg
+a következő kifejezést: `(T|t)he(?!\sfat)`, jelentése: szedd ki az összes
+`The` vagy `the` szót, amelyeket nem követ a `fat` szó (amit még megelőz
+egy szóköz).
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.

+
+### 4.3 Positive Lookbehind
+### 4.3 Positive Lookbehind
+
+Positive lookbehind is used to get all the matches that are preceded by a
+specific pattern. Positive lookbehind is denoted by `(?<=...)`. For example, the
+regular expression `(?<=(T|t)he\s)(fat|mat)` means: get all `fat` or `mat` words
+from input string that are after the word `The` or `the`.
+
+A pozitív hátranézést akkor használjuk, ha kell az összes illeszkedés, amit
+egy megadott minta előz meg. A pozitív hátranézés így van jelölve: `(?<=...)`.
+A `(?<=(T|t)he\s)(fat|mat)` jelentése: szedd ki az összes `fat` vagy `mat` szót
+amelyek a `The` vagy a `the` szavak után vannak.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.

+## 5. Flags
+## 5. Flag-ek
+
+Flags are also called modifiers because they modify the output of a regular
+expression. These flags can be used in any order or combination, and are an
+integral part of the RegExp.
+
+A flag-eket módosítónak hívják, mert módosítják a reguláris kifejezés
+kimenetét. Ezeket a flag-eket bármilyen sorban vagy kombinációban lehet
+használni, a RegExp szerves részét képezik.
+
+|Flag|Description|
+|:----:|----|
+|i|Case insensitive: Sets matching to be case-insensitive.|
+|g|Global Search: Search for a pattern throughout the input string.|
+|m|Multiline: Anchor meta character works on each line.|
+
+|Flag|Leírás|
+|:----:|----|
+|i|Kis-nagybetű érzéketlen: Beállítja, hogy az illeszkedés kis-nagybetű érzéketlen legyen.|
+|g|Globális keresés: A bemeneti szövegben mindenütt keresi az illeszkedéseket.|
+|m|Többsoros: A horgonyok az összes sorra működnek.|
+
+### 5.1 Case Insensitive
+### 5.1 Kis-nagybetű érzéketlen
+
+The `i` modifier is used to perform case-insensitive matching. For example, the
+regular expression `/The/gi` means: uppercase letter `T`, followed by lowercase
+character `h`, followed by character `e`. And at the end of regular expression
+the `i` flag tells the regular expression engine to ignore the case. As you can
+see we also provided `g` flag because we want to search for the pattern in the
+whole input string.
+
+Az `i` módosító beállítja, hogy az illeszkedés ne legyen kis-nagybetű érzékeny.
+Például a `/The/gi` kifejezés jelentése: nagybetűs `T` amit kisbetűs `h`, majd `e`
+követ. A kifejezés végén az `i` megmondja a reguláris kifejezés motornak, hogy
+hagyja figyelmen kívül a betűk méretét. Ahogy látod, megadtuk a `g` flag-et, mert
+az egész bemeneti szövegben akarjuk keresni az illeszkedéseket.
+
+
+"The" => The fat cat sat on the mat.

+
+### 5.2 Global search
+### 5.2 Globális keresés
+
+The `g` modifier is used to perform a global match (find all matches rather than
+stopping after the first match). For example, the regular expression`/.(at)/g`
+means: any character except new line, followed by lowercase character `a`,
+followed by lowercase character `t`. Because we provided `g` flag at the end of
+the regular expression now it will find all matches in the input string, not just the first one (which is the default behavior).
+
+A `g` módosítót arra használjuk, hogy globálisan keressünk illeszkedéseket.
+(Megkeresi az összes előfordulást, nem áll meg az első egyezés után). Például
+a `/.(at)/g` kifejezés jelentése: minden karakter, kivéve a sortörést, amelyet
+`a` és `t` követ. Mivel megadtuk a `g` flag-et, az összes ilyenre fog illeszkedni,
+nem csak az elsőre (ami az alapértelmezett viselkedés). 
+
+
+"/.(at)/" => The fat cat sat on the mat.

+
+### 5.3 Multiline
+### 5.3 Többsoros
+
+The `m` modifier is used to perform a multi-line match. As we discussed earlier
+anchors `(^, $)` are used to check if pattern is the beginning of the input or
+end of the input string. But if we want that anchors works on each line we use
+`m` flag. For example, the regular expression `/at(.)?$/gm` means: lowercase
+character `a`, followed by lowercase character `t`, optionally anything except
+new line. And because of `m` flag now regular expression engine matches pattern
+at the end of each line in a string.
+
+Az `m` módosítót a többsoros illeszkedésekhez használjuk. Ahogy előzőleg beszéltük,
+a horgonyokat `(^, $)` arra használjuk, hogy megnézzük, a minta az eleje, vagy a vége-e
+a vizsgált karakterláncnak. De ha azt szeretnénk, hogy a horgonyok az összes soron
+működjenek, használjuk az `m` módosítót. Például a `/at(.)?$/gm` kifejezés jelentése:
+kisbetűs `a` karakter, amit egy kisbetűs `t` követ, amit opcionálisan bármi követhet,
+kivéve sortörés. És az `m` flag miatt a reguláris kifejezés motor az összes sor
+végéig keres illeszkedést.
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.

-## What is Regular Expression?
 ## Mi az a reguláris kifejezés?
 
-> Regular expression is a group of characters or symbols which is used to find a specific pattern from a text.
 > A reguláris kifejezés karakterek vagy szimbólumok egy csoportja, amelyet egy szövegből adott minták megtalálására használnak.
 
-A regular expression is a pattern that is matched against a subject string from
-left to right. The word "Regular expression" is a mouthful, you will usually
-find the term abbreviated as "regex" or "regexp". Regular expression is used for
-replacing a text within a string, validating form, extract a substring from a
-string based upon a pattern match, and so much more.
-
 A reguláris kifejezés egy olyan minta, amely illeszkedik egy adott karakterláncra
 balról jobbra. Magát a "Regular expression" kifejezést általában rövidítve lehet
 megtalálni, mint "regex" vagy "regexp". A reguláris kifejezést használják szövegrészek
 lecserélésére egy szövegben, űrlapok validálására, szövegrészek kiválasztására
 mintaegyezés alapján egy hosszabb szövegből és így tovább.

 ## 4. Lookaround
 
-Lookbehind and lookahead (also called lookaround) are specific types of
-***non-capturing groups*** (Used to match the pattern but not included in matching

-preceded or followed by another certain pattern. For example, we want to get all
-numbers that are preceded by `$` character from the following input string
-`$4.44 and $10.88`. We will use following regular expression `(?<=\$)[0-9\.]*`
-which means: get all the numbers which contain `.` character and  are preceded

-## 5. Flags
 ## 5. Flag-ek
 
-Flags are also called modifiers because they modify the output of a regular
-expression. These flags can be used in any order or combination, and are an
-integral part of the RegExp.
-
 A flag-eket módosítónak hívják, mert módosítják a reguláris kifejezés
 kimenetét. Ezeket a flag-eket bármilyen sorban vagy kombinációban lehet
 használni, a RegExp szerves részét képezik.
 
-|Flag|Description|
-|:----:|----|
-|i|Case insensitive: Sets matching to be case-insensitive.|
-|g|Global Search: Search for a pattern throughout the input string.|
-|m|Multiline: Anchor meta character works on each line.|

 |Flag|Leírás|
 |:----:|----|
 |i|Kis-nagybetű érzéketlen: Beállítja, hogy az illeszkedés kis-nagybetű érzéketlen legyen.|
 |g|Globális keresés: A bemeneti szövegben mindenütt keresi az illeszkedéseket.|
 |m|Többsoros: A horgonyok az összes sorra működnek.|
 
-### 5.1 Case Insensitive
 ### 5.1 Kis-nagybetű érzéketlen
 
-The `i` modifier is used to perform case-insensitive matching. For example, the
-regular expression `/The/gi` means: uppercase letter `T`, followed by lowercase
-character `h`, followed by character `e`. And at the end of regular expression
-the `i` flag tells the regular expression engine to ignore the case. As you can
-see we also provided `g` flag because we want to search for the pattern in the

 Az `i` módosító beállítja, hogy az illeszkedés ne legyen kis-nagybetű érzékeny.

-anchors `(^, $)` are used to check if pattern is the beginning of the input or
-end of the input string. But if we want that anchors works on each line we use
-`m` flag. For example, the regular expression `/at(.)?$/gm` means: lowercase
-character `a`, followed by lowercase character `t`, optionally anything except
-new line. And because of `m` flag now regular expression engine matches pattern

+## Co to jest wyrażenie regularne?
+
+> Wyrażenie regularne to grupa znaków lub symboli, które służą do odnalezienia określonego wzoru w tekście.
+
+Wyrażenie regularne to wzorzec, który jest dopasowywany do tekstu od lewej
+do prawej strony. Termin "wyrażenie regularne" (ang. "regular expression")
+jest dość długie, więc zazwyczaj używa się skróconej formy "regex" lub "regexp".
+Wyrażenie regularne jest używane do zastępowania tekstu w łańcuchu znaków
+(ang. string), walidacji formularzy, wyodrębniania wycinka z łańcucha
+(ang. substring) według podanego wzorca, i wielu innych.
+
+Wyobraź sobie, że piszesz aplikację i chcesz ustawić reguły dotyczące tego,
+jak użytkownik wybiera swoją nazwę. Chcemy, aby nazwa użytkownika zawierała litery,
+liczby, podkreślenia i myślniki. Chcemy również ograniczyć liczbę znaków w nazwie
+użytkownika, aby nie wyglądała za brzydko. Stosujemy następujące wyrażenie
+regularne, aby sprawdzić poprawność nazwy:
+
+


+

+  Wyrażenie regularne
+

+
+Powyższe wyrażenie akceptuje łańcuchy `john_doe`, `jo-hn_doe`
+i `john12_as`. Odrzuca `Jo` ponieważ łańcuch zawiera dużą literę
+i jest za krótki.

+
+## 1. Najprostsze wyrażenie
+
+Wyrażenie regularne to ciąg znaków, których używamy do przeszukania tekstu.
+Na przykład, wyrażenie `the` oznacza: literę `t`, następującą
+po niej literę `h`, następującą po niej literę `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/dmRygT/1)
+
+Wyrażenie regularne `123` pasuje do łańcucha `123`. Wyrażenie regularne
+jest dopasowywane do danego łańcucha poprzez porównanie każdego znaku,
+jeden po drugim, w wyrażeniu i łańcuchu. Wyrażenia są zwykle wrażliwe
+na wielkość znaków, więc wyrażenie `The` nie pasuje do łańcucha `the`.
+
+
+"The" => The fat cat sat on the mat.

+
+## 2. Metaznaki
+
+Metaznaki to składowe elementy wyrażeń regularnych. Znaki te, nie oznaczają
+siebie samych, są natomiast interpretowane w specjalny sposób.
+Niektóre znaki mają specjalne znaczenie i są zapisywane w kwadratowych nawiasach.
+Metaznaki to:
+
+|Metaznaki|Opis|
+|:----:|----|
+|.|Dowolny znak z wyjątkiem nowej linii.|
+|[ ]|Zakres. Każdy znak zapisany w kwadratowym nawiasie.|
+|[^ ]|Odwrócony zakres. Każdy znak, który nie znajduje się w kwadratowym nawiasie.|
+|*|0 lub więcej poprzedzających znaków.|
+|+|1 lub więcej poprzedzających znaków.|
+|?|0 lub 1 poprzedzających znaków.|
+|{n,m}|Minimum "n" ale nie więcej niż "m" poprzedzających znaków.|
+|(xyz)|Grupowanie znaków. Znaki xyz dokładnie w tej kolejności.|
+|||Alternatywa. Znaki przed symbolem lub za symbolem.|
+|\|Znak ucieczki. Umożliwia używanie zarezerwowanych znaków [ ] ( ) { } . * + ? ^ $ \ |.|
+|^|Oznacza początek wzorca.|
+|$|Oznacza koniec wzorca.|
+
+## 2.1 Kropka
+
+Kropka `.` jest najprostszym przykładem metaznaku. Oznacza dowolny znak z wyłączeniem entera
+i znaków nowej linii. Na przykład, wyrażenie regularne `.ar` oznacza: dowolny znak, następującą
+po niej literę `a`, następującą po niej literę `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 Zestaw znaków
+
+Zestawy znaków nazywane też klasami znaków. Nawiasy kwadratowe służą do określenia zestawów znaków.
+Użycie myślnika wewnątrz zestawu, określa jego zakres. Kolejność znaków w nawiasach kwadratowych
+nie ma znaczenia. Na przykład wyrażenie `[Tt]he` oznacza: dużą literę `T` lub małą `t`,
+następującą po niej literę `h`, następującą po niej literę `e`.
+

+Jednak kropka w zestawie znaków, oznacza dosłownie kropkę. Wyrażenie regularne
+`ar[.]` oznacza: małą literę `a`, następującą po niej literę `r`,
+następującą po niej `.` kropkę.
+
+
+"ar[.]" => A garage is a good place to park a car.

+
+### 2.2.1 Odwrócony zestaw znaków
+
+Generalnie znak karety oznacza początek wyrażenia, ale gdy zostanie użyty zaraz
+za otwierającym nawiasem kwadratowym, odwraca zestaw znaków. Na przykład
+wyrażenie `[^c]ar` oznacza: każdy znak z wyjątkiem `c`,
+następującą po niej literę `a`, następującą po niej literę `r`.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+## 2.3 Powtórzenia
+
+Następujące metaznaki `+`, `*` czy `?` określają ile razy wzorzec może się powtórzyć.
+Te metaznaki zachowują się różnie, w zależności od sytuacji.
+
+### 2.3.1 Gwiazdka
+
+Symbol `*` oznacza zero lub więcej powtórzeń poprzedzających znaków. Wyrażenie
+regularne `a*` oznacza: zero lub więcej powtórzeń poprzedzającej małej
+litery `a`. Ale jeśli występuje po zestawie znaków lub klasie, to oznacza
+powtórzenia całego zestawu lub klasy. Na przykład, wyrażenie regularne
+`[a-z]*` oznacza: każdy ciąg znaków pisany małymi literami.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/7m8me5/1)
+
+Symbol `*` może być użyty z metaznakiem `.` by oznaczyć każdy łańcuch
+znaków `.*`. Symbol `*` może być użyty ze znakiem `\s`
+by znaleźć łańcuch zawierający spacje. Na przykład, wyrażenie
+`\s*cat\s*` oznacza: zero lub więcej spacji, następującą po niej małą literę `c`,
+następującą po niej małą literę `a`, następującą po niej małą literę `t`,
+następujące po niej zero lub więcej spacji.
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/gGrwuz/1)
+
+### 2.3.2 Plus
+
+Symbol `+` oznacza jeden lub więcej powtórzeń poprzedzających znaków. Na przykład,
+wyrażenie `c.+t` oznacza: małą literę `c`, następujący po niej przynajmniej jeden
+dowolny znak, następującą po nim małą literę `t`. W tym wypadku `t` jest ostatnim
+`t` w zdaniu.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 Znak zapytania
+
+W wyrażeniach regularnych znak `?` sprawia, że poprzedzający znak jest opcjonalny.
+Ten symbol oznacza zero lub jedno wystąpienie poprzedzającego znaku. Na przykład,
+wyrażenie regularne `[T]?he` oznacza: opcjonalną dużą literę `T`, następującą
+po niej małą literę `h`, następującą po niej małą literę `e`.
+
+
+"[T]he" => The car is parked in the garage.

+
+## 2.4 Klamry
+
+W wyrażeniach regularnych, klamry zwane również kwantyfikatorami, używane są
+do określenia, ile razy znak lub grupa znaków może się powtórzyć.
+Na przykład wyrażenie regularne `[0-9]{2,3}` oznacza: przynajmniej
+2 znaki, ale nie więcej niż 3 (znaki z zakresu od 0 do 9).
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/juM86s/1)
+
+Możemy opuścić drugą liczbę. Na przykład regularne wyrażenie `[0-9]{2,}`
+oznacza: 2 lub więcej znaków. Jeżeli dodatkowo usuniemy przecinek,
+to wyrażenie `[0-9]{3}` oznacza: dokładnie 3 znaki z zakresu 0 do 9.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+[Przetestuj wyrażenie](https://regex101.com/r/Gdy4w5/1)

+
+## 2.5 Grupa znaków
+
+Grupa znaków to grupa podwzorców, które zapisywane są w nawiasach `(...)`.
+Jak wspominaliśmy wyżej, jeśli w wyrażeniu regularnym wstawimy kwantyfikator po
+znaku, wtedy powtórzy on ten znak. Ale gdy wstawimy kwantyfikator po grupie znaków,
+wtedy cała grupa zostanie powtórzona. Na przykład wyrażenie regularne `(ab)*`
+oznacza zero lub więcej powtórzeń grupy "ab". Możemy także użyć metaznaku
+alternatywy `|` wewnątrz grupy. Na przykład wyrażenie `(c|g|p)ar` oznacza: małą literę `c`,
+`g` lub `p`, następującą po niej literę `a`, następującą po niej literę `r`.
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/tUxrBG/1)
+
+## 2.6 Alternatywa
+
+W wyrażeniach regularnych pionowa kreska `|` oznacza alternatywę.
+Działa jak warunek pomiędzy różnymi wyrażeniami. Teraz możesz pomyśleć, że
+to działa tak samo jak zestaw znaków. Różnica polega na tym, że zestaw znaków
+działa na poziomie znaków, natomiast alternatywa na poziomie wyrażenia. Na przykład
+wyrażenie regularne `(T|t)he|car` oznacza: dużą literę `T` lub małą `t`,
+następującą po niej literę `h`, następującą po niej literę `e` lub `c`, następującą
+po niej literę `a`, następującą po niej literę `r`.
+
+
+"(T|t)he|car" => The car is parked in the garage.
+

+
+## 2.7 Znak ucieczki
+
+Ukośnik `\` w wyrażeniach regularnych jest znakiem ucieczki. Pozwala on
+używać w wyrażeniu zarezerwowanych znaków takich jak `{ } [ ] / \ + * . $ ^ | ?`.
+Aby użyć znaku specjalnego w wyrażeniu, postaw `\` przed nim.
+
+Na przykład wyrażenie `.` dopasowuje każdy znak z wyjątkiem nowej linii.
+Żeby dopasować kropkę `.` w wyrażeniu regularnym, trzeba wstawić przed nią ukośnik.
+Wyrażenie `(f|c|m)at\.?` oznacza: małe litery `f` lub `c` lub `m`, następującą po niej
+literę `a`, następującą po niej literę `t`, następującą kropkę `.`, która jest opcjonalna.
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.
+

+
+## 2.8 Kotwice
+
+W wyrażeniach regularnych używamy kotwic aby sprawdzić czy dopasowywany symbol
+jest pierwszym lub ostatnim symbolem w łańcuchu. Są dwa typy: pierwszy to
+kareta `^`, która sprawdza czy znak jest początkiem łańcucha, drugi to dolar `$`,
+który sprawdza czy znak jest ostatnim elementem łańcucha.
+
+### 2.8.1 Kareta
+
+Kareta `^` sprawdza czy znak jest początkiem łańcucha. Jeżeli użyjemy takiego
+wyrażenia `^a` (jeśli a jest pierwszym znakiem) na łańcuchu `abc` to dopasuje
+nam `a`. Ale jeśli użyjemy takiego wyrażenia `^b` na tym samym łańcuchu, to nie
+zwróci nam nic. Ponieważ w łańcuchu `abc` "b" nie jest pierwszym symbolem.
+Spójrzmy teraz na wyrażenie `^(T|t)he` które oznacza: dużą literę `T` lub małą
+`t`, która jest początkiem łańcucha, następującą po niej literę `h`, następującą
+po niej literę `e`.
+
+
+"(T|t)he" => The car is parked in the garage.

+
+### 2.8.2 Dolar
+
+Symbol dolara `$` używany jest do sprawdzenia czy dopasowywany znak jest ostatni
+w łańcuchu. Na przykład, wyrażenie regularne `(at\.)$` oznacza: małą literę `a`,
+następującą po niej literę `t`, następującą po niej kropkę `.` i na dodatek
+dopasowanie musi być końcem łańcucha.
+
+
+"(at\.)" => The fat cat. sat. on the mat.

+
+##  3. Skróty
+
+W wyrażeniach regularnych znajdziemy także skróty dla popularnych zestawów znaków,
+które ułatwiają pracę z wyrażeniami regularnymi. Skróty wyglądają następująco:
+
+|Skrót|Opis|
+|:----:|----|
+|.|Każdy znak z wyjątkiem nowej linii|
+|\w|Znaki alfanumeryczne: `[a-zA-Z0-9_]`|
+|\W|Znaki nie alfanumeryczne: `[^\w]`|
+|\d|Cyfry: `[0-9]`|
+|\D|Nie cyfry: `[^\d]`|
+|\s|Dowolny biały znak: `[\t\n\f\r\p{Z}]`|
+|\S|Każdy znak oprócz białych: `[^\s]`|
+
+## 4. Lookaround
+
+Lookbehind i lookahead (nazywane również lookaround) to specyficzne typy
+***niezwracających grup*** (dopasowują wzorzec, ale nie zwracają wartości).
+Lookaround używane są w sytuacji, gdy mamy wzorzec i jest on poprzedzony innym wzorcem,
+lub następuje po nim kolejny wzorzec. Na przykład, chcemy mieć wszystkie
+numery, które są poprzedzone znakiem `$` w takim łańcuchu `$4.44 and $10.88`.
+Użyjemy takiego wyrażenia regularnego `(?<=\$)[0-9\.]*` które oznacza: znajdź
+wszystkie liczby ze znakiem `.` poprzedzone znakiem `$`. W wyrażeniach regularnych
+wyróżniamy:
+
+|Symbol|Opis|
+|:----:|----|
+|?=|Lookahead|
+|?!|Odwrócony lookahead|
+|?<=|Lookbehind|
+|?
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/IDDARt/1)
+
+### 4.2 Odwrócony lookahead
+
+Używany jest, gdy potrzebujemy dopasowania z łańcucha, po których nie następują
+żadne wzorce. Odwrócony lookahead definiujemy w nawiasach, stosując znak negacji
+`!` po znaku zapytania, na przykład: `(?!...)`. Popatrzmy na następujące wyrażenie
+`(T|t)he(?!\sfat)` które oznacza: znajdź wszystkie słowa `The` lub `the` w łańcuchu,
+po których nie następuje słowo `fat`, poprzedzone spacją.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/V32Npg/1)
+
+### 4.3 Lookbehind
+
+Lookbehind używany jest do odnalezienia wszystkich dopasowań poprzedzonych konkretnym
+wzorcem. Wyrażenie lookbehind zapisujemy tak: `(?<=...)`. Na przykład, wyrażenie
+`(?<=(T|t)he\s)(fat|mat)` oznacza: znajdź wszystkie słowa `fat` lub `mat` w łańcuchu,
+które znajdują się po słowach `The` lub `the`.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.
+

+
+[Przetestuj wyrażenie](https://regex101.com/r/avH165/1)
+
+### 4.4 Odwrócony lookbehind
+
+Odwrócony używany jest do odnalezienia wszystkich dopasowań niepoprzedzonych konkretnym
+wzorcem. Odwrócony lookbehind zapisujemy tak: `(?
+"(?<!(T|t)he\s)(cat)" => The cat sat on cat.

+
+## 5. Flagi
+
+Flagi nazywane są także modyfikatorami, ponieważ zmieniają wynik wyrażenia regularnego.
+Flagi mogą być używane w każdej kombinacji i są integralną częścią wyrażeń regularnych.
+
+|Flaga|Opis|
+|:----:|----|
+|i|Wielkość znaków: Sprawia, że dopasowanie nie jest wrażliwe na wielkość znaków.|
+|g|Przeszukanie globalne: Wyszukiwanie wzorca w całym łańcuchu.|
+|m|Multilinia: Sprawia, że kotwice działają na każdej linii.|
+
+### 5.1 Wielkość znaków
+
+Modyfikator `i` używany jest, gdy wielkość liter nie ma znaczenia. Na przykład
+wyrażenie `/The/gi` oznacza: dużą literę `T`, następującą po niej literę `h`,
+następującą po niej literę `e`. A na końcu wyrażenia, flaga `i` żeby ignorować
+wielkość znaków. Jak widać, została też użyta flaga `g` ponieważ chcemy przeszukać
+cały łańcuch.
+
+
+"The" => The fat cat sat on the mat.

+[Przetestuj wyrażenie](https://regex101.com/r/ahfiuh/1)
+
+### 5.2 Przeszukiwanie globalne
+
+Modyfikator `g` używany jest do przeszukiwania całego łańcucha (znajdź wszystko,
+a nie tylko zatrzymuj się na pierwszym). Na przykład wyrażenie `/.(at)/g`
+oznacza: każdy znak z wyjątkiem nowej linii, następującą po nim literę `a`,
+następującą po niej literę `t`. Ponieważ użyliśmy na końcu wyrażenia flagi `g`,
+wyszukane zostaną wszystkie dopasowania w łańcuchu, a nie tylko pierwszy (domyślne zachowanie).
+
+
+"/.(at)/" => The fat cat sat on the mat.

+
+### 5.3 Multilinia
+
+Modyfikator `m` używany jest do dopasowywania w wielu liniach. Jak wspominaliśmy
+wcześniej, kotwice `(^, $)` używane są do sprawdzania czy wzorzec jest początkiem
+lub końcem łańcucha. Jeśli chcemy, żeby kotwice zadziałały w każdej linii, używamy
+wtedy flagi `m`. Na przykład wyrażenie `/at(.)?$/gm` oznacza: małą literę `a`,
+następującą po niej małą literę `t`, opcjonalnie dowolny znak z wyjątkiem nowej linii.
+I ponieważ użyliśmy flagi `m` dopasowywane będą wzorce na końcu każdej linii w łańcuchu.
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.

+### 2.5.1 Non-capturing group
+
+A non-capturing group is a capturing group that only matches the characters, but 
+does not capture the group. A non-capturing group is denoted by a `?` followed by a `:`

 ## 4. Olhar ao Redor
 
-Lookbehind (olhar atrás) e lookahead (olhar à frente), às vezes conhecidos como lookarounds (olhar ao redor), são tipos específicos de ***grupo de não captura*** (utilizado para encontrar um padrão, mas não incluí-lo na lista de ocorrêncoas). Lookarounds são usados quando temos a condição de que determinado padrão seja precedido ou seguido de outro padrão. Por exemplo, queremos capturar todos os números precedidos do caractere `$` da seguinte string de entrada: `$4.44 and $10.88`. Vamos usar a seguinte expressão regular `(?<=\$)[0-9\.]*` que significa: procure todos os números que contêm o caractere `.` e são precedidos pelo caractere `$`. À seguir estão os lookarounds que são utilizados em expressões regulares:

+## Что такое Регулярное выражение?
+
+> Регулярное выражение - это группа букв или символов, которая используется для поиска определенного шаблона в тексте.
+
+Регулярное выражение - это шаблон, сопоставляемый с искомой строкой слева направо. 
+Термин «Регулярное выражение» сложно произносить каждый раз, поэтому, обычно, вы будете сталкиваться с сокращениями "регэкспы" или "регулярки". 
+Регулярные выражения используются для замен текста внутри строк, валидации форм,
+извлечений подстрок по определенным шаблонам и множества других вещей.
+
+Представьте, что вы пишете приложение и хотите установить правила, по которым пользователь выбирает свой юзернейм.  Мы хотим, чтобы имя пользователя содержало буквы, цифры, подчеркивания и дефисы.  Мы также хотим ограничить количество символов в имени пользователя, чтобы оно не выглядело безобразно. 
+Для этого, используем следующее регулярное выражение:
+
+
+


+

+  Regular expression
+

+
+Регулярное выражения выше может принимать строки `john_doe`,` jo-hn_doe` и `john12_as`. 
+Оно не валидирует `Jo`, поскольку эта строка содержит заглавные буквы, а также она слишком короткая.

+
+## 1. Совпадения.
+
+В сущности, регулярное выражение - это просто набор символов, который мы используем для поиска в тексте. 
+Например, регулярное выражение `the` состоит из буквы` t`, за которой следует буква `h`, за которой следует буква `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/dmRygT/1)
+
+Регулярное выражение `123` соответствует строке` 123`. Регулярное выражение сопоставляется с входной строкой, сравнивая 
+каждый символ в регулярном выражении с каждым символом во входной строке по одному символу за другим. Регулярные выражения 
+обычно чувствительны к регистру, поэтому регулярное выражение `The` не будет соответствовать строке` the`.
+
+
+"The" => The fat cat sat on the mat.

+
+## 2. Метасимволы
+
+Метасимволы это блоки, из которых строятся регулярные выражения. Метасимволы не означают что-то сами по себе,
+вместо этого они интерпретируются для распознавания специальных групп символов. Некоторые метасимволы имеют 
+особые обозначения и пишутся в квадратных скобках. Существуют следующие метасимволы:
+
+|Метасимволы|Описание|
+|:----:|----|
+|.|Точка соответствует любому отдельному символу, кроме разрыва строки.|
+|[ ]|Класс символов. Находить любые символы заключенные в квадратных скобках.|
+|[^ ]|Отрицание класа символов. Находить любые символы не заключенные в квадратных скобках.|
+|*|Находить 0 или более повторений предыдущего символа.|
+|+|Находить 1 или более повторений предыдущего символа.|
+|?|Сделать предыдущий символ необязательным.|
+|{n,m}|Скобки. Находить по крайней мере "n" но не более чем "m" повторений предыдущего символа.|
+|(xyz)|Группа символов. Находить только символы xyz в указанном порядке.|
+|||Чередование. Находить либо буквы до, либо буквы после символа.|
+|\|Экранирование. Позволяет находить зарезервированные символы: [ ] ( ) { } . * + ? ^ $ \ ||
+|^|Обозначает начало пользовательского ввода.| 
+|$|Обозначает конец пользовательского ввода.|
+
+## 2.1 Точка
+
+Точка `.` это простейший пример метасимвола. Метасимвол `.`
+находит любой отдельный символ. Точка не будет находить символы перехода или перевода строки.
+For example, the regular expression `.ar` means: any character, followed by the
+letter `a`, followed by the letter `r`. Например, регулярное выражение '.ar' обозначает: любой символ, за которым следуют буквы ` a` и `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 Набор символов.
+
+Набор символов также называется классом символов. Квадратные скобки используются
+для определения набора символов. Дефис используется для указания диапазона символов. 
+Порядок следования символов, заданный в квадратных скобках, не важен. Например, 
+регулярное выражение  `[Tt]he` обозначает заглавную 'T' или строчную 't', за которой следуют буквы 'h' и 'e'.
+
+
+"[Tt]he" => The car parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/2ITLQ4/1)
+
+Точка внутри набора символов, однако, обозначает непосредственно точку, как символ. 
+Регулярное выражение `ar[.]` обозначает строчную 'a', за которой следует 'r', за которой следует '.' (символ точки).
+
+
+"ar[.]" => A garage is a good place to park a car.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/wL3xtE/1)
+
+### 2.2.1 Отрицание набора символов
+
+Знак вставки '^' обозначает начало строки, однако, когда вы вписываете его после открытия квадратных скобок, он отрицает набор символов. 
+Например, регулярное выражение `[^c]ar` обозначает любой символ, кроме 'c', за которым следуют буквы 'a' и 'r'.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/nNNlq3/1)
+
+## 2.3 Повторения
+
+Символы `+`, `*` or `?` используются для обозначения того, как сколько раз появляется какой-либо подшаблон. 
+Данные метасимволы могут вести себя по-разному, в зависимости от ситуации.
+
+### 2.3.1 Звёздочка
+
+Символ `*` обозначает ноль или более повторений предыдущего совпадения. 
+Регулярное выражение `a *` означает ноль или более повторений предыдущего
+строчного символа `a`. Если же символ появляется после набора или класса символов,
+он находит повторения всего набора символов. Например, регулярное выражение `[a-z] *`
+означает любое количество строчных букв в строке.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/7m8me5/1)
+
+Символы можно комбинировать, так, например, символ `*` может использоваться с метасимволом `.` 
+для поиска одной строки с произвольным содержанием `. * `. Символ `*` может использоваться
+с символом пробела `\ s`, чтобы находить строки с символами пробела. Например, выражение 
+`\ s * cat \ s *` означает: ноль или более пробелов, за которыми следует слово  `cat`,
+за которым следует ноль или более символов пробела.
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/gGrwuz/1)
+
+### 2.3.2 Плюс
+
+Символ `+` соответствует одному или более повторению предыдущего символа. Например, 
+регулярное выражение `c.+t` означает строчную `c`, за которой следует по крайней мере один символ, 
+следом за которым идёт символ `t`. Стоит уточнить, что в данном шаблоне, `t` является последним` t` в предложении.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 Знак вопроса
+
+В регулярном выражении метасимвол `?` делает предыдущий символ необязательным. 
+Этот символ соответствует нулю или одному экземпляру предыдущего символа.
+Например, регулярное выражение `[T]?he` означает  необязательную заглавную букву `T`, за которой следуют символы 'h' и 'e'.
+
+
+"[T]he" => The car is parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/cIg9zm/1)
+
+
+"[T]?he" => The car is parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/kPpO2x/1)
+
+## 2.4 Фигурные скобки
+
+В фигурных скобках, которые также называются квантификаторами, указывается, 
+сколько раз символ или группа символов могут повторяться. Например, регулярное выражение 
+`[0-9] {2,3}` означает совпадение не менее 2 но не более 3 цифр в диапазоне от 0 до 9.
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/juM86s/1)
+
+Уберём второй номер (цифру 3), тогда,  регулярное выражение `[0-9] {2,}` будет означать 
+совпадение 2 или более цифр. Если мы также удалим запятую, то регулярное выражение
+`[0-9] {3}` будет означать  совпадение точно с 3 цифрами.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/Gdy4w5/1)
+
+
+"[0-9]{3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/Sivu30/1)
+
+## 2.5 Скобочные группы
+
+Скобочные группы это группы подшаблонов, которые написаны в круглых скобках
+`(...)`. Как мы уже говорили ранее в регулярном выражении, если мы поставим квантификатор
+после символа, он будет повторять предыдущий символ. Но если мы поставим квантификатор после 
+скобочной группы, он будет искать всю группу. Например, регулярное выражение `(ab) *` соответствует
+нулю или более повторений символа "ab". Мы также можем использовать метасимвол чередования `|`
+внутри скобочной группы. Например, регулярное выражение `(c|g|p)ar` означает поиск одной из строчных букв `c`,
+`g` или `p`, за которыми следуют буквы 'a' и 'r'.
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/tUxrBG/1)
+
+Обратите внимание, что скобочные группы не только находят, но и захватывают символы для использования на родительском языке. 
+Родительским языком может быть python, javascript или практически любой язык, который реализует использование регулярных выражений как параметров функций.
+
+### 2.5.1 Не запоминающие скобочные группы
+
+Бывает так, что группу определить нужно, а вот запоминать их содержимое в массиве не требуется.
+Подобный трюк осуществляется при помощи зарезервированной комбинации `?:` 
+в круглых скобках `(...)`. Например, регулярное выражение `(?:c|g|p)ar` будет находить такие же шаблоны как и 
+`(c|g|p)ar`, однако скобочная группа при этом создана не будет. 
+
+
+"(?:c|g|p)ar" => The car is parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/Rm7Me8/1)
+
+Не запоминающиеся группы пригодиться, когда они используются в функциях поиска и замены
+или в сочетании со скобочными группами, например, для предпросмотра при создании скобочной группы или другого вида выходных данных, 
+смотрите также [4. Опережающие и ретроспективные проверки](#4-опережающие-и-ретроспективные-проверки).
+
+## 2.6 Альтернация
+
+В регулярных выражениях, вертикальная черта `|` используется для определения альтернации (чередования).
+Альтернация по своей сути похожа на оператор ИЛИ между логическими выражениями. Может создаться впечатление, что
+чередование это то же самое, что и определение набора символов. Однако, большая разница между ними в том, что 
+набор символов работает на уровне конкретных символов, в то время как альтернация работает на уровне выражений.
+Например, регулярное выражение `(T|t)he|car` объединяет два шаблона (заглавная `T` ИЛИ строчная `t`, с продолжением из 'h' и 'e') и шаблон
+(строчная `c`, затем строчная `a`, за которой следует строчная `r`). Таким образом, в поиске будет участвовать любой из данных шаблонов,
+по аналогии с логической операцией ИЛИ в программировании и алгебре выражений.
+
+
+"(T|t)he|car" => The car is parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/fBXyX0/1)
+
+## 2.7 Экранирование спецсимволов
+
+Обратный слэш `\` используется в регулярных выражениях для экранирования следующего символа. 
+Это позволяет формировать шаблоны с поиском зарезервированных символамов, таких как `{ } [ ] / \ + * . $ ^ | ?`. 
+Для использования спецсимвола в шаблоне необходимо указать символ '\' перед ним.
+
+Как упомянуто выше, символ `.` является зарезервированным и соответствует любому значению, кроме символа новой строки. 
+Бывают ситуации, когда необходимо найти точку в предложении, для таких случаев применимо экранирование. Рассмотрим выражение
+`(f|c|m)at\.?`, что соответствует следующему шаблону: стройчный символ `f`, `c` или `m`,  за которым следует строчные буквы `a` и `t`, с опциональной `.` точкой в конце.
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/DOc5Nu/1)
+
+## 2.8 Якоря
+
+Понятие якорей в регулярных выражениях используется для обозначения проверок, является ли 
+соответствующий символ начальным или конечным символом входной строки. Якоря бывают двух типов:
+Первый тип - Каретка `^`, проверяет, является ли соответствующий символ начальным символом в тексте.
+Второй тип - Доллар `$`, проверяет, является ли соответствующий символ последним символом входной строки.
+
+### 2.8.1 Каретка
+
+Символ каретки `^` используется для проверки, является ли соответствующий символ первым символом входной строки. 
+Если мы применяем следующее регулярное выражение `^a` (если a является начальным символом) для строки `abc`,
+совпадение будет соответствовать букве `a`. Если же мы используем регулярное выражение `^b` на той же строке,
+мы не получим совпадения, поскольку во входящей строке  `abc` "b"  не является первым символом. Рассмотрим другое
+регулярное выражение: `^(T|t)he`, обозначающее заглавную `T` или строчную `t` как первый символ, за которым следуют
+символы букв 'h' и 'e'. Cоответственно:
+
+
+"(T|t)he" => The car is parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/5ljjgB/1)
+
+
+"^(T|t)he" => The car is parked in the garage.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/jXrKne/1)
+
+### 2.8.2 Доллар
+
+Символ доллара `$` используется для проверки, является ли соответствующий символ
+последним символом входной строки. Например, регулярное выражение `(at\.)$` последовательность из
+строчной `a`, строчной `t`, и точки `.`, ключевой момент в том, что благодаря доллару этот шаблон будет
+находить совпадения только в том случае, если будет наблюдаться в конце строки. Например:
+
+
+"(at\.)" => The fat cat. sat. on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/y4Au4D/1)

+
+##  3. Наборы сокращений и диапазоны
+
+Регулярные выражения предоставляют сокращения для часто используемых наборов символов,
+которые предлагают удобные сокращения для часто используемых регулярных выражений. 
+Наборы сокращенных символов следующие:
+
+|Сокращение|Описание|
+|:----:|----|
+|.|Любой символ кроме символа новой строки|
+|\w|Поиск буквенно-цифрового диапазона символов: `[a-zA-Z0-9_]`|
+|\W|Поиск не буквенно-цифрового диапазона символов: `[^\w]`|
+|\d|Поиск цифр: `[0-9]`|
+|\D|Поиск всего, что не является цифрой: `[^\d]`|
+|\s|Поиск пробелов и символов начала строки: `[\t\n\f\r\p{Z}]`|
+|\S|Поиск всего кроме пробелов и символов начала строки: `[^\s]`|
+
+## 4. Опережающие и ретроспективные проверки
+
+Опережающие и ретроспективные проверки (в английской литературе lookbehind, lookahead) это особый вид 
+***не запоминающих скобочных групп*** (находящих совпадения, но не добавляющих в массив). 
+Данные проверки используются, мы знаем, что шаблон предшествует или сопровождается другим шаблоном.
+Например, мы хотим получить получить цену в долларах `$`, из следующей входной строки
+`$4.44 and $10.88`. Для этого используем следующее регулярное выражение `(?<=\$)[0-9\.]*`, означающее
+получение всех дробных (с точкой `.`) цифр, которым предшествует знак доллара `$`. Существуют 
+следующие виды проверок:
+
+|Символ|Описание|
+|:----:|----|
+|?=|Положительное опережающее условие|
+|?!|Отрицательное опережающее условие|
+|?<=|Положительное ретроспективное условие|
+|?
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.

+
+### 4.2 Отрицательное опережающее условие
+
+Отрицательное опережающее условие работает по обратному принципу: используется, когда нам нужно получить 
+все совпадения из входной строки, за которыми НЕ следует определенный шаблон. Отрицательное опережающее условие
+определяется таким же образом, как и позитивное, с той лишь разницей, что вместо равенства `=` мы ставим
+восклицательный знак `!` (отрицание) например: `(?!...)`. Рассмотрим выражение `(T|t)he(?!\sfat)`, в котором мы
+находим все `The` или `the` слова из входной строки, за которыми не следует слово `fat`.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.

+
+### 4.3 Положительное ретроспективное условие
+
+Положительное ретроспективное условие используется чтобы найти все совпадения, которым предшествует
+определенный шаблон. Условие определяется как `(?<=...)`. Например, выражение `(?<=(T|t)he\s)(fat|mat)` означает, 
+найти все слова `fat` или `mat` из входной строки, которым предшествует слово `The` or `the`.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.

+
+## 5. Флаги
+
+Флаги, также называемые модификаторами, изменяют вывод регулярного выражения. 
+Эти флаги могут быть использованы в любом порядке или комбинации, и являются
+неотъемлемой частью регулярных выражений.
+
+|Флаг|Описание|
+|:----:|----|
+|i|Поиск без учета регистра|
+|g|Глобальный поиск: поиск шаблона во всем входном тексте|
+|m|Мультистроковый поиск: Якоря применяются к каждой строке.|
+
+### 5.1 Поиск без учета регистра
+
+Модификатор `i` используется для поиска без учета регистра. Например, регулярное выражение
+`/The/gi` означает заглавную `T` следом строчные `h` и `e`. В конце регулярного выражения флаг `i`, 
+указывающий движку регулярных выражений игнорировать регистр. Помимо  `i`, для поиска шаблона во
+всем входном тексте, использован флаг `g`.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/dpQyf9/1)
+
+
+"/The/gi" => The fat cat sat on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/ahfiuh/1)
+
+### 5.2 Глобальный поиск
+
+Модификатор `g` используется для выполнения глобального сопоставления (найти все совпадения, а не останавливаться после первого).
+Например, регулярное выражение `/.(at)/g` означает любой символ кроме символа новой строки, следом строчная `a`, далее строчная `t`. 
+Из-за использования флага `g` в конце регулярного выражения, теперь оно найдет все совпадения во входной строке, а не остановится на первом 
+(что является поведением по умолчанию).
+
+
+"/.(at)/" => The fat cat sat on the mat.

+
+
+"/.(at)/g" => The fat cat sat on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/dO1nef/1)
+
+### 5.3 Мультистроковый поиск
+
+Модификатор `m` используется для многострочного поиска. Как мы обсуждали ранее,
+якоря `(^, $)` используются для проверки, является ли шаблон началом или концом входной строки.
+Но если мы хотим, чтобы якоря работали в каждой строке, мы используем флаг `m`.  Например, 
+регулярное выражение `/at(.)?$/gm` означает строчную  `a`, следом строчная `t` и любой
+символ кроме начала новой строки, идущий опционально (не обязательно). Из-за флага `m` механизм 
+регулярных выражений будет искать данный шаблон в конце каждой строки в тексте.
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.
+

+
+[Запустить регулярное выражение](https://regex101.com/r/hoGMkP/1)

+"/.at(.)?$/gm" => The fat

+[Запустить регулярное выражение](https://regex101.com/r/E88WE2/1)
+
+## 6. Жадные vs ленивые квантификаторы
+По умолчанию регулярное выражение выполняет жадное сопоставление, то есть оно будет 
+искать совпадения как можно дольше. Мы можем использовать `?` для ленивого поиска, который
+будет стремиться быть как можно более коротким по времени.
+
+
+"/(.*at)/" => The fat cat sat on the mat.

 Для использования спецсимвола в шаблоне необходимо указать символ '\' перед ним.

 Бывают ситуации, когда необходимо найти точку в предложении, для таких случаев применимо экранирование. Рассмотрим выражение
-`(f|c|m)at\.?`, что соответствует следующему шаблону: стройчный символ `f`, `c` или `m`,  за которым следует строчные буквы `a` и `t`, с опциональной `.` точкой в конце.

+## Biểu thức chính quy là gì?
+
+> Biểu thức chính quy là một nhóm các ký tự hoặc ký hiệu được sử dụng để tìm một mẫu cụ thể từ một văn bản.
+
+Biểu thức chính quy là một khuôn mẫu được khớp với chuỗi các từ, từ trái sang phải. Từ "Biểu thức chính quy" là một câu cửa miệng, bạn thường sẽ tìm thấy thuật ngữ viết tắt là "regex" hoặc "regexp". Biểu thức chính quy được sử dụng để thay thế một văn bản trong một chuỗi, xác thực mẫu, trích xuất một chuỗi con từ một chuỗi dựa trên khớp mẫu và hơn thế nữa.
+
+Hãy tưởng tượng bạn đang viết một ứng dụng và bạn muốn đặt quy tắc khi người dùng chọn tên người dùng của họ. Chúng tôi muốn cho phép tên người dùng chứa các chữ cái, số, dấu gạch dưới và dấu gạch nối. Chúng tôi cũng muốn giới hạn số lượng ký tự trong tên người dùng để nó trông không xấu. Chúng tôi sử dụng biểu thức chính quy sau để xác thực tên người dùng:
+
+
+


+

+  Regular expression
+

+
+Trên biểu thức chính quy có thể chấp nhận các chuỗi `john_doe`, `jo-hn_doe` và `john12_as`. Nó không khớp với `Jo` vì chuỗi đó chứa chữ hoa và nó quá ngắn.

+## 1. Basic Matchers
+
+A regular expression is just a pattern of characters that we use to perform
+search in a text.  For example, the regular expression `the` means: the letter
+`t`, followed by the letter `h`, followed by the letter `e`.
+
+
+Biểu thức chính quy chỉ là một mẫu các ký tự mà chúng ta sử dụng để thực hiện tìm kiếm trong văn bản. Ví dụ, biểu thức chính quy `the` có nghĩa là: chữ `t`, tiếp theo là chữ `h`, tiếp theo là chữ `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/dmRygT/1)
+
+Biểu thức chính quy `123` khớp với chuỗi `123`. Biểu thức chính quy được khớp với chuỗi đầu vào bằng cách so sánh từng ký tự trong biểu thức chính quy với từng ký tự trong chuỗi đầu vào, lần lượt từng ký tự. Biểu thức chính quy thường phân biệt chữ hoa chữ thường nên biểu thức chính quy `The` sẽ không khớp với chuỗi `the`.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/1paXsy/1)
+
+## 2. Meta Characters
+
+Các ký tự `meta` là các khối xây dựng của các biểu thức chính quy. Các ký tự `meta` không biểu diễn chính nó mà thay vào đó được diễn giải theo một cách đặc biệt nào đó. Một số ký tự `meta` có ý nghĩa đặc biệt và được viết bên trong dấu ngoặc vuông. Các ký tự meta như sau:
+
+|Meta character|Description|
+|:----:|----|
+|.|Khớp với tất cả các kí tự trừ dấu xuống dòng.|
+|[ ]|Lớp kí tự. Khớp với bất kỳ ký tự nào nằm giữa dấu ngoặc vuông.|
+|[^ ]|Lớp kí tự phủ định. Khớp với bất kỳ ký tự nào không có trong dấu ngoặc vuông.|
+|*|Khớp 0 hoặc nhiều lần lặp lại của kí tự trước.|
+|+|Khớp 1 hoặc nhiều lần lặp lại của kí tự trước.|
+|?|Làm cho kí tự trước tùy chọn.|
+|{n,m}|Braces. Khớp ít nhất là "n" nhưng không nhiều hơn "m" lặp lại của kí tự trước.|
+|(xyz)|Nhóm kí tự. Khớp các ký tự xyz theo thứ tự chính xác đó.|
+|||Thay thế. Khớp các ký tự trước hoặc ký tự sau ký hiệu.|
+|\|Thoát khỏi kí tự tiếp theo. Điều này cho phép bạn khớp các ký tự dành riêng [ ] ( ) { } . * + ? ^ $ \ ||
+|^|Khớp với sự bắt đầu của đầu vào.|
+|$|Khớp với kết thúc đầu vào.|
+
+## 2.1 Full stop
+
+
+Full stop `.`  là ví dụ đơn giản nhất về ký tự meta. Kí tự meta `.`
+khớp với bất kì kí tự nào. Nó sẽ không khớp kí tự trả về (return) hoặc xuống dòng (newline)
+
+Ví dụ, biểu thức chính quy `.ar` có ý nghĩa: bất kỳ ký tự nào, theo sau là chữ `a`, tiếp theo là chữ `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 Character set
+
+Bộ ký tự cũng được gọi là lớp kí tự. Dấu ngoặc vuông được sử dụng để chỉ định bộ ký tự. Sử dụng dấu gạch nối bên trong bộ ký tự để chỉ định phạm vi của các ký tự. Thứ tự của phạm vi ký tự trong dấu ngoặc vuông không quan trọng. 
+
+Ví dụ: biểu thức chính quy `[Tt]he` có nghĩa là: chữ hoa `T` hoặc chữ thường `t`, theo sau là chữ `h`, tiếp theo là chữ `e`.
+
+
+"[Tt]he" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/2ITLQ4/1)
+
+
+Tuy nhiên, khoảng thời gian bên trong một bộ ký tự có nghĩa là một khoảng thời gian theo nghĩa đen. Biểu thức chính quy `ar[.]` Có nghĩa là: ký tự chữ thường `a`, theo sau là chữ `r`, theo sau là kí tự `.` .
+
+
+"ar[.]" => A garage is a good place to park a car.
+

+
+[Test the regular expression](https://regex101.com/r/wL3xtE/1)
+
+### 2.2.1 Negated character set
+
+Nói chung, biểu tượng dấu mũ biểu thị sự bắt đầu của chuỗi, nhưng khi nó được gõ sau dấu ngoặc vuông mở, nó sẽ phủ định bộ ký tự. Ví dụ: biểu thức chính quy `[^ c]ar` có nghĩa là: bất kỳ ký tự nào ngoại trừ `c`, theo sau là ký tự `a`, theo sau là chữ `r`.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+
+
+
+## 2.3 Repetitions
+
+Theo dõi các ký tự meta, `+`, `*` hoặc `?` được sử dụng để xác định số lần mô hình con (subpattern) có thể xảy ra. Những kí tự meta này hành động khác nhau trong các tình huống khác nhau.
+
+
+### 2.3.1 The Star
+
+Biểu tượng `*` khớp 0 hoặc nhiều lần lặp lại của trình so khớp trước. Biểu thức chính quy `a*` có nghĩa là: 0 hoặc nhiều lần lặp lại ký tự chữ thường trước `a`. Nhưng nếu nó xuất hiện sau một bộ ký tự hoặc lớp thì nó sẽ tìm thấy sự lặp lại của toàn bộ bộ ký tự. Ví dụ: biểu thức chính quy `[a-z]*` có nghĩa là: bất kỳ số lượng chữ cái viết thường trong một hàng.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[Test the regular expression](https://regex101.com/r/7m8me5/1)
+
+Biểu tượng `*` có thể được sử dụng với ký tự meta. để khớp với bất kỳ chuỗi ký tự nào `.*` . Biểu tượng `*` có thể được sử dụng với ký tự khoảng trắng `\s` để khớp với một chuỗi các ký tự khoảng trắng. 
+
+Ví dụ: biểu thức `\s*cat\s*` có nghĩa là: không hoặc nhiều khoảng trắng, theo sau là ký tự chữ thường `c`, theo sau là ký tự chữ thường `a`, theo sau là ký tự chữ thường `t`, tiếp theo là 0 hoặc nhiều khoảng trắng.
+
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[Test the regular expression](https://regex101.com/r/gGrwuz/1)
+
+
+
+
+### 2.3.2 The Plus
+
+The symbol `+` matches one or more repetitions of the preceding character. For
+example, the regular expression `c.+t` means: lowercase letter `c`, followed by
+at least one character, followed by the lowercase character `t`. It needs to be
+clarified that `t` is the last `t` in the sentence.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 The Question Mark
+
+Trong biểu thức chính quy các ký tự meta `?` làm cho ký tự trước là một tùy chọn. Biểu tượng này khớp với 0 hoặc một thể hiện (instance ) của ký tự trước. Ví dụ: biểu thức chính quy `[T]?he` có nghĩa là: Tùy chọn chữ hoa chữ `T`, theo sau là ký tự chữ thường `h`, tiếp theo là ký tự chữ thường `e`.
+
+
+"[T]he" => The car is parked in the garage.

+"[T]?he" => The car is parked in the garage.

+
+
+## 2.4 Braces
+
+
+Trong các dấu ngoặc nhọn thông thường còn được gọi là bộ định lượng được sử dụng để chỉ định số lần mà một ký tự hoặc một nhóm ký tự có thể được lặp lại. Ví dụ: biểu thức chính quy `[0-9]{2,3}` có nghĩa là: Ghép ít nhất 2 chữ số nhưng không quá 3 (ký tự trong phạm vi từ 0 đến 9).
+
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/juM86s/1)
+
+
+Chúng ta có thể bỏ qua số thứ hai. Ví dụ: biểu thức chính quy `[0-9]{2,}` có nghĩa là: Ghép 2 chữ số trở lên. Nếu chúng tôi cũng xóa dấu phẩy, biểu thức chính quy `[0-9]{3}` có nghĩa là: Ghép chính xác 3 chữ số.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+[Test the regular expression](https://regex101.com/r/Gdy4w5/1)

+
+
+## 2.5 Capturing Group
+
+A capturing group is a group of sub-patterns that is written inside Parentheses 
+`(...)`. Like As we discussed before that in regular expression if we put a quantifier 
+after a character then it will repeat the preceding character. But if we put quantifier
+after a capturing group then it repeats the whole capturing group. For example,
+the regular expression `(ab)*` matches zero or more repetitions of the character
+"ab". We can also use the alternation `|` meta character inside capturing group.
+For example, the regular expression `(c|g|p)ar` means: lowercase character `c`,
+`g` or `p`, followed by character `a`, followed by character `r`.
+
+
+Một nhóm capturing là một nhóm các mẫu con được viết bên trong Dấu ngoặc đơn `(...)`. Giống như chúng ta đã thảo luận trước đó trong biểu thức chính quy nếu chúng ta đặt một bộ định lượng sau một ký tự thì nó sẽ lặp lại ký tự trước. Nhưng nếu chúng ta đặt bộ định lượng sau một nhóm capturing thì nó lặp lại toàn bộ nhóm capturing. Ví dụ: biểu thức chính quy `(ab)*` khớp với 0 hoặc nhiều lần lặp lại của ký tự "ab". Chúng ta cũng có thể sử dụng luân phiên `|` kí tự meta trong nhóm capturing. Ví dụ: biểu thức chính quy `(c|g|p)ar` có nghĩa là: ký tự chữ thường `c`, `g` hoặc `p`, theo sau là ký tự `a`, tiếp theo là ký tự `r`.
+
+
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/tUxrBG/1)
+
+Note that capturing groups do not only match but also capture the characters for use in 
+the parent language. The parent language could be python or javascript or virtually any
+language that implements regular expressions in a function definition.
+
+
+Lưu ý rằng các nhóm capturing không chỉ khớp mà còn capturing các ký tự để sử dụng trong ngôn ngữ gốc. Ngôn ngữ gốc có thể là python hoặc javascript hoặc hầu như bất kỳ ngôn ngữ nào thực hiện các biểu thức chính quy trong định nghĩa hàm.
+
+
+### 2.5.1 Non-capturing group
+
+A non-capturing group is a capturing group that only matches the characters, but 
+does not capture the group. A non-capturing group is denoted by a `?` followed by a `:` 
+within parenthesis `(...)`. For example, the regular expression `(?:c|g|p)ar` is similar to 
+`(c|g|p)ar` in that it matches the same characters but will not create a capture group.
+
+
+
+Nhóm không capturing là nhóm capturing chỉ khớp với các ký tự, nhưng không capturing được nhóm. Một nhóm không capturing được ký hiệu là `?` theo sau là `:` trong ngoặc đơn `(...)`. 
+
+Ví dụ: biểu thức chính quy `(?:c|g|p)ar` tương tự như `(c|g|p)ar` ở chỗ nó khớp với các ký tự giống nhau nhưng sẽ không tạo nhóm capturing.
+
+
+"(?:c|g|p)ar" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/Rm7Me8/1)
+
+Các nhóm không capturing có thể có ích khi được sử dụng trong chức năng tìm và thay thế hoặc khi trộn với các nhóm capturing để giữ tổng quan khi sản xuất bất kỳ loại đầu ra nào khác. Xem thêm [4. Lookaround](#4-lookaround). 
+
+
+## 2.6 Alternation
+
+Trong một biểu thức chính quy, thanh dọc `|` được sử dụng để xác định xen kẽ. Sự xen kẽ giống như một câu lệnh OR giữa nhiều biểu thức. Bây giờ, bạn có thể nghĩ rằng bộ ký tự và luân phiên hoạt động theo cùng một cách. Nhưng sự khác biệt lớn giữa bộ ký tự và xen kẽ là bộ ký tự hoạt động ở cấp độ ký tự nhưng xen kẽ hoạt động ở cấp độ biểu thức. 
+
+Ví dụ: biểu thức chính quy `(T|t)he|car` có nghĩa là: hoặc (ký tự chữ `T` hoặc chữ thường `t`, theo sau là ký tự chữ thường `h`, tiếp theo là ký tự chữ thường `e`) OR (ký tự chữ thường `c`, tiếp theo là ký tự chữ thường `a`, theo sau bằng ký tự viết thường `r`). Lưu ý rằng tôi đặt dấu ngoặc đơn cho rõ ràng, để cho thấy rằng một trong hai biểu thức trong ngoặc đơn có thể được đáp ứng và nó sẽ khớp.
+
+
+"(T|t)he|car" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/fBXyX0/1)
+
+## 2.7 Escaping special character
+
+Backslash `\` is used in regular expression to escape the next character. This
+allows us to specify a symbol as a matching character including reserved
+characters `{ } [ ] / \ + * . $ ^ | ?`. To use a special character as a matching
+character prepend `\` before it.
+
+For example, the regular expression `.` is used to match any character except
+newline. Now to match `.` in an input string the regular expression
+`(f|c|m)at\.?` means: lowercase letter `f`, `c` or `m`, followed by lowercase
+character `a`, followed by lowercase letter `t`, followed by optional `.`
+character.
+
+
+Dấu gạch chéo ngược `\` được sử dụng trong biểu thức chính quy để thoát ký tự tiếp theo. Điều này cho phép chúng tôi chỉ định một biểu tượng là một ký tự phù hợp bao gồm các ký tự dành riêng `{} [] / \ *. $ ^ | ?` . Để sử dụng một ký tự đặc biệt, ta dùng `\` làm ký tự trùng khớp trước kí tự ta muốn dùng.
+
+Ví dụ, biểu thức chính quy `.` được sử dụng để khớp với bất kỳ ký tự nào ngoại trừ dòng mới. Bây giờ để phù hợp `.` trong một chuỗi đầu vào, biểu thức chính quy `(f|c|m)at\.?` có nghĩa là: chữ thường `f`, `c` hoặc `m`, theo sau là ký tự chữ thường `a`, tiếp theo là chữ thường chữ `t`, theo sau là tùy chọn `.` tính cách.
+
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.

+[Test the regular expression](https://regex101.com/r/DOc5Nu/1)
+
+
+## 2.8 Anchors
+
+
+Trong các biểu thức chính quy, chúng tôi sử dụng các anchors để kiểm tra xem biểu tượng phù hợp là biểu tượng bắt đầu hay biểu tượng kết thúc của chuỗi đầu vào. Các anchors có hai loại: Loại thứ nhất là Caret `^` kiểm tra xem ký tự khớp có phải là ký tự bắt đầu của đầu vào không và loại thứ hai là Dollar `$` kiểm tra xem ký tự khớp có phải là ký tự cuối cùng của chuỗi đầu vào không.
+
+
+
+
+### 2.8.1 Caret
+
+
+Biểu tượng Caret `^` được sử dụng để kiểm tra xem ký tự khớp có phải là ký tự đầu tiên của chuỗi đầu vào không. Nếu chúng ta áp dụng biểu thức chính quy sau `^a` ( nếu a là ký hiệu bắt đầu) cho chuỗi đầu vào `abc` thì nó khớp với `a`. Nhưng nếu chúng ta áp dụng biểu thức chính quy `^b` trên chuỗi đầu vào ở trên thì nó không khớp với bất cứ thứ gì. Bởi vì trong chuỗi đầu vào `abc` "b" không phải là ký hiệu bắt đầu. Chúng ta hãy xem một biểu thức chính quy khác `^(T|t)he` có nghĩa là: ký tự chữ hoa `T` hoặc ký tự chữ thường `t` là ký hiệu bắt đầu của chuỗi đầu vào, tiếp theo là ký tự chữ thường `h`, tiếp theo là ký tự chữ thường `e`.

+### 2.8.2 Dollar
+
+
+Biểu tượng Dollar `$` được sử dụng để kiểm tra xem ký tự khớp có phải là ký tự cuối cùng của chuỗi đầu vào không. Ví dụ: biểu thức chính quy `(at\.)$` có nghĩa là: ký tự chữ thường `a`, theo sau là ký tự chữ thường `t`, theo sau là `.` ký tự và bộ so khớp phải là cuối chuỗi.

+
+
+
+"(at\.)" => The fat cat. sat. on the mat.

+
+##  3. Shorthand Character Sets
+
+
+
+Biểu thức chính quy cung cấp các shorthand cho các bộ ký tự thường được sử dụng, cung cấp các shorthand thuận tiện cho các biểu thức thông thường được sử dụng. Các bộ ký tự shorthand như sau:
+
+
+|Shorthand|Description|
+|:----:|----|
+|.| Bất kỳ kí tự nào ngoại trừ dòng mới|
+|\w|Khớp các ký tự chữ và số: `[a-zA-Z0-9_]`|
+|\W|Khớp các ký tự không phải chữ và số: `[^\w]`|
+|\d|khớp với số trong khoảng: `[0-9]`|
+|\D|Khớp không có chữ số: `[^\d]`|
+|\s|Khớp các ký tự khoảng trắng: `[\t\n\f\r\p{Z}]`|
+|\S|Khớp với ký tự không phải khoảng trắng: `[^\s]`|
+
+## 4. Lookaround
+
+Lookbehind và lookahead (còn được gọi là lookaround) là các loại nhóm ***không capturing*** cụ thể (Được sử dụng để khớp với mẫu nhưng không được bao gồm trong danh sách phù hợp). `Lookarounds` sử dụng khi chúng ta có điều kiện mẫu này được đi trước hoặc theo sau bởi một mẫu khác. 
+
+Ví dụ: chúng tôi muốn nhận tất cả các số có trước ký tự `$` từ chuỗi đầu vào sau `$4,44 và $10,88`. Chúng tôi sẽ sử dụng biểu thức chính quy sau `(?<=\$)[0-9\.]*` có nghĩa là: lấy tất cả các số có chứa `.` ký tự và đứng trước ký tự `$`. Sau đây là những cái nhìn được sử dụng trong các biểu thức thông thường:
+
+|Kí hiệu|Mô tả|
+|:----:|----|
+|?=|Positive Lookahead|
+|?!|Negative Lookahead|
+|?<=|Positive Lookbehind|
+|?
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/IDDARt/1)
+
+### 4.2 Negative Lookahead
+
+Negative lookahead is used when we need to get all matches from input string
+that are not followed by a pattern. Negative lookahead is defined same as we define
+positive lookahead but the only difference is instead of equal `=` character we
+use negation `!` character i.e. `(?!...)`. Let's take a look at the following
+regular expression `(T|t)he(?!\sfat)` which means: get all `The` or `the` words
+from input string that are not followed by the word `fat` precedes by a space
+character.
+
+
+
+
+
+
+`Negative lookahead` được sử dụng khi chúng ta cần lấy tất cả các kết quả khớp từ chuỗi đầu vào không được theo sau bởi một mẫu. `Negative lookahead` được định nghĩa giống như chúng ta định nghĩa `positive lookahead` nhưng sự khác biệt duy nhất là thay vì bằng ký tự `=` chúng ta sử dụng kí tự phủ định `!`  tức là `(?! ...)`. 
+
+Chúng ta hãy xem biểu thức chính quy sau đây: `(T|t)he(?!\sfat)` có nghĩa là: lấy tất cả các từ `The` hoặc `the` từ chuỗi đầu vào không được đứng trước bởi từ `fat` trước một ký tự khoảng trắng.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.

+
+### 4.3 Positive Lookbehind
+

+## 5. Flags
+
+Flags are also called modifiers because they modify the output of a regular
+expression. These flags can be used in any order or combination, and are an
+integral part of the RegExp.
+
+
+Cờ (flags) cũng được gọi là bổ nghĩa (modifiers) vì chúng sửa đổi đầu ra của biểu thức chính quy. Các cờ này có thể được sử dụng theo bất kỳ thứ tự hoặc kết hợp nào và là một phần không thể thiếu của RegExp.
+
+
+
+|Cờ|Mô tả|
+|:------:|----|
+|i|Case insensitive: Đặt khớp với mẫu không phân biệt chữ hoa chữ thường.|
+|g|Global Search: Tìm kiếm một mẫu trong suốt chuỗi đầu vào.|
+|m|Multiline: ký tự Anchor meta hoạt động trên mỗi dòng.|
+
+### 5.1 Case Insensitive
+
+The `i` modifier is used to perform case-insensitive matching. For example, the
+regular expression `/The/gi` means: uppercase letter `T`, followed by lowercase
+character `h`, followed by character `e`. And at the end of regular expression
+the `i` flag tells the regular expression engine to ignore the case. As you can
+see we also provided `g` flag because we want to search for the pattern in the
+whole input string.
+
+
+
+Công cụ sửa đổi `i` được sử dụng để thực hiện khớp không phân biệt chữ hoa chữ thường. 
+
+Ví dụ: biểu thức chính quy `/The/gi` có nghĩa là: chữ hoa chữ `T`, theo sau là ký tự chữ thường `h`, tiếp theo là ký tự `e`. Và ở cuối biểu thức chính quy, cờ `i` báo cho công cụ biểu thức chính quy bỏ qua trường hợp này. Như bạn có thể thấy, chúng tôi cũng đã cung cấp cờ `g` vì chúng tôi muốn tìm kiếm mẫu trong toàn bộ chuỗi đầu vào.
+
+
+"The" => The fat cat sat on the mat.

+
+### 5.2 Global search
+
+
+Công cụ sửa đổi `g` được sử dụng để thực hiện khớp toàn cầu (tìm tất cả các từ có thể khớp thay vì dừng sau lần khớp đầu tiên). 
+
+Ví dụ: biểu thức chính quy `/.(at)/g` có nghĩa là: bất kỳ ký tự nào ngoại trừ dòng mới, theo sau là ký tự chữ thường `a`, tiếp theo là ký tự chữ thường `t`. Vì chúng tôi đã cung cấp cờ `g` ở cuối biểu thức chính quy nên bây giờ nó sẽ tìm thấy tất cả các kết quả khớp trong chuỗi đầu vào, không chỉ là đầu tiên (là hành vi mặc định).
+
+
+"/.(at)/" => The fat cat sat on the mat.

+
+### 5.3 Multiline
+
+
+Công cụ sửa đổi `m` được sử dụng để thực hiện khớp nhiều dòng. Như chúng ta đã thảo luận về các anchors `(^, $)` trước đó, được sử dụng để kiểm tra xem mẫu là phần đầu của phần đầu vào hay phần cuối của chuỗi đầu vào. Nhưng nếu chúng ta muốn các anchors hoạt động trên mỗi dòng, chúng ta sử dụng cờ `m`. 
+
+Ví dụ: biểu thức chính quy `/at(.)?$/gm` có nghĩa là: ký tự chữ thường `a`, theo sau là ký tự chữ thường `t`, tùy chọn mọi thứ trừ dòng mới. Và vì cờ `m` bây giờ công cụ biểu thức chính quy khớp với mẫu ở cuối mỗi dòng trong một chuỗi.
+
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.

+
+
+## 6. Greedy vs lazy matching
+By default regex will do greedy matching , means it will match as long as
+possible. we can use `?` to match in lazy way means as short as possible
+
+
+Theo mặc định, regex sẽ thực hiện greedy matching, có nghĩa là nó sẽ khớp càng lâu càng tốt. chúng ta có thể sử dụng `?` để khớp theo cách lười biếng có nghĩa là càng ngắn càng tốt

-A regular expression is just a pattern of characters that we use to perform
-search in a text.  For example, the regular expression `the` means: the letter
-`t`, followed by the letter `h`, followed by the letter `e`.
-

 ## 2.5 Capturing Group
 
-A capturing group is a group of sub-patterns that is written inside Parentheses 
-`(...)`. Like As we discussed before that in regular expression if we put a quantifier 
-after a character then it will repeat the preceding character. But if we put quantifier
-after a capturing group then it repeats the whole capturing group. For example,
-the regular expression `(ab)*` matches zero or more repetitions of the character
-"ab". We can also use the alternation `|` meta character inside capturing group.
-For example, the regular expression `(c|g|p)ar` means: lowercase character `c`,
-`g` or `p`, followed by character `a`, followed by character `r`.
-
-
 Một nhóm capturing là một nhóm các mẫu con được viết bên trong Dấu ngoặc đơn `(...)`. Giống như chúng ta đã thảo luận trước đó trong biểu thức chính quy nếu chúng ta đặt một bộ định lượng sau một ký tự thì nó sẽ lặp lại ký tự trước. Nhưng nếu chúng ta đặt bộ định lượng sau một nhóm capturing thì nó lặp lại toàn bộ nhóm capturing. Ví dụ: biểu thức chính quy `(ab)*` khớp với 0 hoặc nhiều lần lặp lại của ký tự "ab". Chúng ta cũng có thể sử dụng luân phiên `|` kí tự meta trong nhóm capturing. Ví dụ: biểu thức chính quy `(c|g|p)ar` có nghĩa là: ký tự chữ thường `c`, `g` hoặc `p`, theo sau là ký tự `a`, tiếp theo là ký tự `r`.

-Note that capturing groups do not only match but also capture the characters for use in 
-the parent language. The parent language could be python or javascript or virtually any
-language that implements regular expressions in a function definition.
-
 
 Lưu ý rằng các nhóm capturing không chỉ khớp mà còn capturing các ký tự để sử dụng trong ngôn ngữ gốc. Ngôn ngữ gốc có thể là python hoặc javascript hoặc hầu như bất kỳ ngôn ngữ nào thực hiện các biểu thức chính quy trong định nghĩa hàm.
 
 
 ### 2.5.1 Non-capturing group
 
-A non-capturing group is a capturing group that only matches the characters, but 
-does not capture the group. A non-capturing group is denoted by a `?` followed by a `:` 
-within parenthesis `(...)`. For example, the regular expression `(?:c|g|p)ar` is similar to 
-`(c|g|p)ar` in that it matches the same characters but will not create a capture group.

 Nhóm không capturing là nhóm capturing chỉ khớp với các ký tự, nhưng không capturing được nhóm. Một nhóm không capturing được ký hiệu là `?` theo sau là `:` trong ngoặc đơn `(...)`.

 ## 2.7 Escaping special character
 
-Backslash `\` is used in regular expression to escape the next character. This
-allows us to specify a symbol as a matching character including reserved
-characters `{ } [ ] / \ + * . $ ^ | ?`. To use a special character as a matching
-character prepend `\` before it.
-
-For example, the regular expression `.` is used to match any character except
-newline. Now to match `.` in an input string the regular expression

-character `a`, followed by lowercase letter `t`, followed by optional `.`
-character.
-
 
 Dấu gạch chéo ngược `\` được sử dụng trong biểu thức chính quy để thoát ký tự tiếp theo. Điều này cho phép chúng tôi chỉ định một biểu tượng là một ký tự phù hợp bao gồm các ký tự dành riêng `{} [] / \ *. $ ^ | ?` .

 ### 4.2 Negative Lookahead
 
-Negative lookahead is used when we need to get all matches from input string
-that are not followed by a pattern. Negative lookahead is defined same as we define
-positive lookahead but the only difference is instead of equal `=` character we
-use negation `!` character i.e. `(?!...)`. Let's take a look at the following

+## Was sind reguläre Ausdrücke
+
+> Ein regulärer Ausdruck ist eine Gruppe von Buchstaben und Symbolen, die benutzt werden um ein spezifisches Muster in einem Text zu finden
+Ein regulärer Ausdruch ist ein Muster, das mit einem zu durchsuchenden Text von links nach rechts abgeglichen wird. Die Bezeichnung
+"Regulärer Ausdruck" ist in der Praxis unüblich und stattdessen wird häufig die Englische Abkürzung "Regex" verwendet. Reguläre
+Ausdrücke werden verwendet um Fragemente eines Textes zu ersetzen, Formulare zu validieren, Segmente eines Textes anhand eines
+Musters zu extrahieren und für vieles mehr.
+
+Angenommen Du schreibst eine Applikation und möchtest die Regeln definieren, nach denen ein Benutzer seinen Benutzernamen auswählen
+kann. Wir möchten festlegen, dass der Benutzernamen Buchstaben, Ziffern, Unter- und Bindestriche beinhalten darf. Außerdem wollen
+wir die Anzahl der Zeichen limitieren, damit der Name nicht unlesbar wird. Dazu verwenden wir den folgenden regulären Ausdruck um
+den Benutzernamen zu überprüfen:
+


+

+  Regular expression
+

+
+Der abgebildete reguläre Ausdruck erlaubt bspw. folgende Eingaben `john_doe`, `jo-hn_doe` und `john12_as`. Der Eingabe `Jo` wird
+nicht akzeptiert, da sie einen Großbuchstaben enthält und zu kurz ist.

+## 1. Basis Vergleiche
+
+A regular expression is just a pattern of characters that we use to perform
+search in a text.  For example, the regular expression `the` means: the letter
+`t`, followed by the letter `h`, followed by the letter `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/dmRygT/1)
+
+The regular expression `123` matches the string `123`. The regular expression is
+matched against an input string by comparing each character in the regular
+expression to each character in the input string, one after another. Regular
+expressions are normally case-sensitive so the regular expression `The` would
+not match the string `the`.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/1paXsy/1)
+
+## 2. Meta Characters
+
+Meta characters are the building blocks of the regular expressions.  Meta
+characters do not stand for themselves but instead are interpreted in some
+special way. Some meta characters have a special meaning and are written inside
+square brackets. The meta characters are as follows:
+
+|Meta character|Description|
+|:----:|----|
+|.|Period matches any single character except a line break.|
+|[ ]|Character class. Matches any character contained between the square brackets.|
+|[^ ]|Negated character class. Matches any character that is not contained between the square brackets|
+|*|Matches 0 or more repetitions of the preceding symbol.|
+|+|Matches 1 or more repetitions of the preceding symbol.|
+|?|Makes the preceding symbol optional.|
+|{n,m}|Braces. Matches at least "n" but not more than "m" repetitions of the preceding symbol.|
+|(xyz)|Character group. Matches the characters xyz in that exact order.|
+|||Alternation. Matches either the characters before or the characters after the symbol.|
+|\|Escapes the next character. This allows you to match reserved characters [ ] ( ) { } . * + ? ^ $ \ ||
+|^|Matches the beginning of the input.|
+|$|Matches the end of the input.|
+
+## 2.1 Full stop
+
+Full stop `.` is the simplest example of meta character. The meta character `.`
+matches any single character. It will not match return or newline characters.
+For example, the regular expression `.ar` means: any character, followed by the
+letter `a`, followed by the letter `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 Character set
+
+Character sets are also called character class. Square brackets are used to
+specify character sets. Use a hyphen inside a character set to specify the
+characters' range. The order of the character range inside square brackets
+doesn't matter. For example, the regular expression `[Tt]he` means: an uppercase
+`T` or lowercase `t`, followed by the letter `h`, followed by the letter `e`.
+
+
+"[Tt]he" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/2ITLQ4/1)
+
+A period inside a character set, however, means a literal period. The regular
+expression `ar[.]` means: a lowercase character `a`, followed by letter `r`,
+followed by a period `.` character.
+
+
+"ar[.]" => A garage is a good place to park a car.
+

+
+[Test the regular expression](https://regex101.com/r/wL3xtE/1)
+
+### 2.2.1 Negated character set
+
+In general, the caret symbol represents the start of the string, but when it is
+typed after the opening square bracket it negates the character set. For
+example, the regular expression `[^c]ar` means: any character except `c`,
+followed by the character `a`, followed by the letter `r`.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/nNNlq3/1)
+
+## 2.3 Repetitions
+
+Following meta characters `+`, `*` or `?` are used to specify how many times a
+subpattern can occur. These meta characters act differently in different
+situations.
+
+### 2.3.1 The Star
+
+The symbol `*` matches zero or more repetitions of the preceding matcher. The
+regular expression `a*` means: zero or more repetitions of preceding lowercase
+character `a`. But if it appears after a character set or class then it finds
+the repetitions of the whole character set. For example, the regular expression
+`[a-z]*` means: any number of lowercase letters in a row.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[Test the regular expression](https://regex101.com/r/7m8me5/1)
+
+The `*` symbol can be used with the meta character `.` to match any string of
+characters `.*`. The `*` symbol can be used with the whitespace character `\s`
+to match a string of whitespace characters. For example, the expression
+`\s*cat\s*` means: zero or more spaces, followed by lowercase character `c`,
+followed by lowercase character `a`, followed by lowercase character `t`,
+followed by zero or more spaces.
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[Test the regular expression](https://regex101.com/r/gGrwuz/1)
+
+### 2.3.2 The Plus
+
+The symbol `+` matches one or more repetitions of the preceding character. For
+example, the regular expression `c.+t` means: lowercase letter `c`, followed by
+at least one character, followed by the lowercase character `t`. It needs to be
+clarified that `t` is the last `t` in the sentence.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 The Question Mark
+
+In regular expression the meta character `?` makes the preceding character
+optional. This symbol matches zero or one instance of the preceding character.
+For example, the regular expression `[T]?he` means: Optional the uppercase
+letter `T`, followed by the lowercase character `h`, followed by the lowercase
+character `e`.
+
+
+"[T]he" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/cIg9zm/1)
+
+
+"[T]?he" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/kPpO2x/1)
+
+## 2.4 Braces
+
+In regular expression braces that are also called quantifiers are used to
+specify the number of times that a character or a group of characters can be
+repeated. For example, the regular expression `[0-9]{2,3}` means: Match at least
+2 digits but not more than 3 ( characters in the range of 0 to 9).
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/juM86s/1)
+
+We can leave out the second number. For example, the regular expression
+`[0-9]{2,}` means: Match 2 or more digits. If we also remove the comma the
+regular expression `[0-9]{3}` means: Match exactly 3 digits.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/Gdy4w5/1)
+
+
+"[0-9]{3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/Sivu30/1)
+
+## 2.5 Capturing Group
+
+A capturing group is a group of sub-patterns that is written inside Parentheses 
+`(...)`. Like as we discussed before that in regular expression if we put a quantifier 
+after a character then it will repeat the preceding character. But if we put quantifier
+after a capturing group then it repeats the whole capturing group. For example,
+the regular expression `(ab)*` matches zero or more repetitions of the character
+"ab". We can also use the alternation `|` meta character inside capturing group.
+For example, the regular expression `(c|g|p)ar` means: lowercase character `c`,
+`g` or `p`, followed by character `a`, followed by character `r`.
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/tUxrBG/1)
+
+Note that capturing groups do not only match but also capture the characters for use in 
+the parent language. The parent language could be python or javascript or virtually any
+language that implements regular expressions in a function definition.
+
+### 2.5.1 Non-capturing group
+
+A non-capturing group is a capturing group that only matches the characters, but 
+does not capture the group. A non-capturing group is denoted by a `?` followed by a `:` 
+within parenthesis `(...)`. For example, the regular expression `(?:c|g|p)ar` is similar to 
+`(c|g|p)ar` in that it matches the same characters but will not create a capture group.
+
+
+"(?:c|g|p)ar" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/Rm7Me8/1)
+
+Non-capturing groups can come in handy when used in find-and-replace functionality or 
+when mixed with capturing groups to keep the overview when producing any other kind of output. 
+See also [4. Lookaround](#4-lookaround).
+
+## 2.6 Alternation
+
+In a regular expression, the vertical bar `|` is used to define alternation.
+Alternation is like an OR statement between multiple expressions. Now, you may be
+thinking that character set and alternation works the same way. But the big
+difference between character set and alternation is that character set works on
+character level but alternation works on expression level. For example, the
+regular expression `(T|t)he|car` means: either (uppercase character `T` or lowercase
+`t`, followed by lowercase character `h`, followed by lowercase character `e`) OR
+(lowercase character `c`, followed by lowercase character `a`, followed by
+lowercase character `r`). Note that I put the parentheses for clarity, to show that either expression
+in parentheses can be met and it will match.
+
+
+"(T|t)he|car" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/fBXyX0/1)
+
+## 2.7 Escaping special character
+
+Backslash `\` is used in regular expression to escape the next character. This
+allows us to specify a symbol as a matching character including reserved
+characters `{ } [ ] / \ + * . $ ^ | ?`. To use a special character as a matching
+character prepend `\` before it.
+
+For example, the regular expression `.` is used to match any character except
+newline. Now to match `.` in an input string the regular expression
+`(f|c|m)at\.?` means: lowercase letter `f`, `c` or `m`, followed by lowercase
+character `a`, followed by lowercase letter `t`, followed by optional `.`
+character.
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/DOc5Nu/1)
+
+## 2.8 Anchors
+
+In regular expressions, we use anchors to check if the matching symbol is the
+starting symbol or ending symbol of the input string. Anchors are of two types:
+First type is Caret `^` that check if the matching character is the start
+character of the input and the second type is Dollar `$` that checks if matching
+character is the last character of the input string.
+
+### 2.8.1 Caret
+
+Caret `^` symbol is used to check if matching character is the first character
+of the input string. If we apply the following regular expression `^a` (if a is
+the starting symbol) to input string `abc` it matches `a`. But if we apply
+regular expression `^b` on above input string it does not match anything.
+Because in input string `abc` "b" is not the starting symbol. Let's take a look
+at another regular expression `^(T|t)he` which means: uppercase character `T` or
+lowercase character `t` is the start symbol of the input string, followed by
+lowercase character `h`, followed by lowercase character `e`.
+
+
+"(T|t)he" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/5ljjgB/1)
+
+
+"^(T|t)he" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/jXrKne/1)
+
+### 2.8.2 Dollar
+
+Dollar `$` symbol is used to check if matching character is the last character
+of the input string. For example, regular expression `(at\.)$` means: a
+lowercase character `a`, followed by lowercase character `t`, followed by a `.`
+character and the matcher must be end of the string.
+
+
+"(at\.)" => The fat cat. sat. on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/y4Au4D/1)
+
+
+"(at\.)$" => The fat cat. sat. on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/t0AkOd/1)
+
+##  3. Shorthand Character Sets
+
+Regular expression provides shorthands for the commonly used character sets,
+which offer convenient shorthands for commonly used regular expressions. The
+shorthand character sets are as follows:
+
+|Shorthand|Description|
+|:----:|----|
+|.|Any character except new line|
+|\w|Matches alphanumeric characters: `[a-zA-Z0-9_]`|
+|\W|Matches non-alphanumeric characters: `[^\w]`|
+|\d|Matches digit: `[0-9]`|
+|\D|Matches non-digit: `[^\d]`|
+|\s|Matches whitespace character: `[\t\n\f\r\p{Z}]`|
+|\S|Matches non-whitespace character: `[^\s]`|
+
+## 4. Lookaround
+
+Lookbehind and lookahead (also called lookaround) are specific types of
+***non-capturing groups*** (Used to match the pattern but not included in matching
+list). Lookarounds are used when we have the condition that this pattern is
+preceded or followed by another certain pattern. For example, we want to get all
+numbers that are preceded by `$` character from the following input string
+`$4.44 and $10.88`. We will use following regular expression `(?<=\$)[0-9\.]*`
+which means: get all the numbers which contain `.` character and  are preceded
+by `$` character. Following are the lookarounds that are used in regular
+expressions:
+
+|Symbol|Description|
+|:----:|----|
+|?=|Positive Lookahead|
+|?!|Negative Lookahead|
+|?<=|Positive Lookbehind|
+|?
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/IDDARt/1)
+
+### 4.2 Negative Lookahead
+
+Negative lookahead is used when we need to get all matches from input string
+that are not followed by a pattern. Negative lookahead is defined same as we define
+positive lookahead but the only difference is instead of equal `=` character we
+use negation `!` character i.e. `(?!...)`. Let's take a look at the following
+regular expression `(T|t)he(?!\sfat)` which means: get all `The` or `the` words
+from input string that are not followed by the word `fat` precedes by a space
+character.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/V32Npg/1)
+
+### 4.3 Positive Lookbehind
+
+Positive lookbehind is used to get all the matches that are preceded by a
+specific pattern. Positive lookbehind is denoted by `(?<=...)`. For example, the
+regular expression `(?<=(T|t)he\s)(fat|mat)` means: get all `fat` or `mat` words
+from input string that are after the word `The` or `the`.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/avH165/1)
+
+### 4.4 Negative Lookbehind
+
+Negative lookbehind is used to get all the matches that are not preceded by a
+specific pattern. Negative lookbehind is denoted by `(?
+"(?<!(T|t)he\s)(cat)" => The cat sat on cat.
+

+
+[Test the regular expression](https://regex101.com/r/8Efx5G/1)
+
+## 5. Flags
+
+Flags are also called modifiers because they modify the output of a regular
+expression. These flags can be used in any order or combination, and are an
+integral part of the RegExp.
+
+|Flag|Description|
+|:----:|----|
+|i|Case insensitive: Sets matching to be case-insensitive.|
+|g|Global Search: Search for a pattern throughout the input string.|
+|m|Multiline: Anchor meta character works on each line.|
+
+### 5.1 Case Insensitive
+
+The `i` modifier is used to perform case-insensitive matching. For example, the
+regular expression `/The/gi` means: uppercase letter `T`, followed by lowercase
+character `h`, followed by character `e`. And at the end of regular expression
+the `i` flag tells the regular expression engine to ignore the case. As you can
+see we also provided `g` flag because we want to search for the pattern in the
+whole input string.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/dpQyf9/1)
+
+
+"/The/gi" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/ahfiuh/1)
+
+### 5.2 Global search
+
+The `g` modifier is used to perform a global match (find all matches rather than
+stopping after the first match). For example, the regular expression`/.(at)/g`
+means: any character except new line, followed by lowercase character `a`,
+followed by lowercase character `t`. Because we provided `g` flag at the end of
+the regular expression now it will find all matches in the input string, not just the first one (which is the default behavior).
+
+
+"/.(at)/" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/jnk6gM/1)
+
+
+"/.(at)/g" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/dO1nef/1)
+
+### 5.3 Multiline
+
+The `m` modifier is used to perform a multi-line match. As we discussed earlier
+anchors `(^, $)` are used to check if pattern is the beginning of the input or
+end of the input string. But if we want that anchors works on each line we use
+`m` flag. For example, the regular expression `/at(.)?$/gm` means: lowercase
+character `a`, followed by lowercase character `t`, optionally anything except
+new line. And because of `m` flag now regular expression engine matches pattern
+at the end of each line in a string.
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.

+[Test the regular expression](https://regex101.com/r/hoGMkP/1)

+## 6. Greedy vs lazy matching
+By default regex will do greedy matching , means it will match as long as
+possible. we can use `?` to match in lazy way means as short as possible

-A regular expression is just a pattern of characters that we use to perform
-search in a text.  For example, the regular expression `the` means: the letter
-`t`, followed by the letter `h`, followed by the letter `e`.
+Ein regulärer Ausdruck ist ein einfaches Muster von Zeichen, welches für eine Suche in Text genutzt wird. Zum Beispiel, der reguläre Ausdruck `the` meint: der Buchstabe `t`, gefolgt durch den Buchstaben `h`, gefolgt durch den Buchstaben `e`.

-The regular expression `123` matches the string `123`. The regular expression is
-matched against an input string by comparing each character in the regular
-expression to each character in the input string, one after another. Regular
-expressions are normally case-sensitive so the regular expression `The` would
-not match the string `the`.
+Der reguläre Ausdruck `123` entspricht der Zeichenkette `123`. Dieser reguläre Ausdruck kann mit einer Zeichenkette verglichen werden, in dem jedes Zeichen in dem regulären Ausdruck nacheinander verglichen wird.

-special way. Some meta characters have a special meaning and are written inside
-square brackets. The meta characters are as follows:
+Sonderzeichen sind Bausteine von regulären Ausdrücken. Sonderzeichen stehen nicht für sich selbst, sondern werden in speziellen Fällen interpretiert. Einige Sonderzeichen haben eine besondere Bedeutung und sind innerhalb eckiger Klammern `[]`. Folgende Sonderzeichen sind möglich:

 ## Qué es una expresión regular?
 > Una expresión regular es un grupo de caracteres o símbolos, los cuales son usados para buscar un patrón específico dentro de un texto.
 
-Una expresión regular es un patrón que que se compara con una cadena de caracteres de izquierda a derecha. La palabra "expresión regular" puede también ser escrita como "Regex" o "Regexp". Las expresiones regulares se utilizan para remplazar un texto dentro de una cadena de caracteres (*string*), validar formularios, extraer una porción de una cadena de caracteres (*substring*) basado en la coincidencia de una patrón, y muchas cosas más.

 Imagina que estás escribiendo una aplicación y quieres agregar reglas para cuando el usuario elija su nombre de usuario. Nosotros queremos permitir que el nombre de usuario contenga letras, números, guión bajo (raya), y guión medio. También queremos limitar el número de caracteres en el nombre de usuario para que no se vea feo. Para ello usamos la siguiente expresión regular para validar el nombre de usuario.

+## 1. Basic Matchers
+
+A regular expression is just a pattern of characters that we use to perform
+search in a text.  For example, the regular expression `the` means: the letter
+`t`, followed by the letter `h`, followed by the letter `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/dmRygT/1)
+
+The regular expression `123` matches the string `123`. The regular expression is
+matched against an input string by comparing each character in the regular
+expression to each character in the input string, one after another. Regular
+expressions are normally case-sensitive so the regular expression `The` would
+not match the string `the`.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/1paXsy/1)
+
+## 2. Meta Characters
+
+Meta characters are the building blocks of the regular expressions.  Meta
+characters do not stand for themselves but instead are interpreted in some
+special way. Some meta characters have a special meaning and are written inside
+square brackets. The meta characters are as follows:
+
+|Meta character|Description|
+|:----:|----|
+|.|Period matches any single character except a line break.|
+|[ ]|Character class. Matches any character contained between the square brackets.|
+|[^ ]|Negated character class. Matches any character that is not contained between the square brackets|
+|*|Matches 0 or more repetitions of the preceding symbol.|
+|+|Matches 1 or more repetitions of the preceding symbol.|
+|?|Makes the preceding symbol optional.|
+|{n,m}|Braces. Matches at least "n" but not more than "m" repetitions of the preceding symbol.|
+|(xyz)|Character group. Matches the characters xyz in that exact order.|
+|||Alternation. Matches either the characters before or the characters after the symbol.|
+|\|Escapes the next character. This allows you to match reserved characters [ ] ( ) { } . * + ? ^ $ \ ||
+|^|Matches the beginning of the input.|
+|$|Matches the end of the input.|
+
+## 2.1 Full stop
+
+Full stop `.` is the simplest example of meta character. The meta character `.`
+matches any single character. It will not match return or newline characters.
+For example, the regular expression `.ar` means: any character, followed by the
+letter `a`, followed by the letter `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 Character set
+
+Character sets are also called character class. Square brackets are used to
+specify character sets. Use a hyphen inside a character set to specify the
+characters' range. The order of the character range inside square brackets
+doesn't matter. For example, the regular expression `[Tt]he` means: an uppercase
+`T` or lowercase `t`, followed by the letter `h`, followed by the letter `e`.
+
+
+"[Tt]he" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/2ITLQ4/1)
+
+A period inside a character set, however, means a literal period. The regular
+expression `ar[.]` means: a lowercase character `a`, followed by letter `r`,
+followed by a period `.` character.
+
+
+"ar[.]" => A garage is a good place to park a car.
+

+
+[Test the regular expression](https://regex101.com/r/wL3xtE/1)
+
+### 2.2.1 Negated character set
+
+In general, the caret symbol represents the start of the string, but when it is
+typed after the opening square bracket it negates the character set. For
+example, the regular expression `[^c]ar` means: any character except `c`,
+followed by the character `a`, followed by the letter `r`.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/nNNlq3/1)
+
+## 2.3 Repetitions
+
+Following meta characters `+`, `*` or `?` are used to specify how many times a
+subpattern can occur. These meta characters act differently in different
+situations.
+
+### 2.3.1 The Star
+
+The symbol `*` matches zero or more repetitions of the preceding matcher. The
+regular expression `a*` means: zero or more repetitions of preceding lowercase
+character `a`. But if it appears after a character set or class then it finds
+the repetitions of the whole character set. For example, the regular expression
+`[a-z]*` means: any number of lowercase letters in a row.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[Test the regular expression](https://regex101.com/r/7m8me5/1)
+
+The `*` symbol can be used with the meta character `.` to match any string of
+characters `.*`. The `*` symbol can be used with the whitespace character `\s`
+to match a string of whitespace characters. For example, the expression
+`\s*cat\s*` means: zero or more spaces, followed by lowercase character `c`,
+followed by lowercase character `a`, followed by lowercase character `t`,
+followed by zero or more spaces.
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[Test the regular expression](https://regex101.com/r/gGrwuz/1)
+
+### 2.3.2 The Plus
+
+The symbol `+` matches one or more repetitions of the preceding character. For
+example, the regular expression `c.+t` means: lowercase letter `c`, followed by
+at least one character, followed by the lowercase character `t`. It needs to be
+clarified that `t` is the last `t` in the sentence.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 The Question Mark
+
+In regular expression the meta character `?` makes the preceding character
+optional. This symbol matches zero or one instance of the preceding character.
+For example, the regular expression `[T]?he` means: Optional the uppercase
+letter `T`, followed by the lowercase character `h`, followed by the lowercase
+character `e`.
+
+
+"[T]he" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/cIg9zm/1)
+
+
+"[T]?he" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/kPpO2x/1)
+
+## 2.4 Braces
+
+In regular expression braces that are also called quantifiers are used to
+specify the number of times that a character or a group of characters can be
+repeated. For example, the regular expression `[0-9]{2,3}` means: Match at least
+2 digits but not more than 3 ( characters in the range of 0 to 9).
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/juM86s/1)
+
+We can leave out the second number. For example, the regular expression
+`[0-9]{2,}` means: Match 2 or more digits. If we also remove the comma the
+regular expression `[0-9]{3}` means: Match exactly 3 digits.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/Gdy4w5/1)
+
+
+"[0-9]{3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/Sivu30/1)
+
+## 2.5 Capturing Group
+
+A capturing group is a group of sub-patterns that is written inside Parentheses 
+`(...)`. Like as we discussed before that in regular expression if we put a quantifier 
+after a character then it will repeat the preceding character. But if we put quantifier
+after a capturing group then it repeats the whole capturing group. For example,
+the regular expression `(ab)*` matches zero or more repetitions of the character
+"ab". We can also use the alternation `|` meta character inside capturing group.
+For example, the regular expression `(c|g|p)ar` means: lowercase character `c`,
+`g` or `p`, followed by character `a`, followed by character `r`.
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/tUxrBG/1)
+
+Note that capturing groups do not only match but also capture the characters for use in 
+the parent language. The parent language could be python or javascript or virtually any
+language that implements regular expressions in a function definition.
+
+### 2.5.1 Non-capturing group
+
+A non-capturing group is a capturing group that only matches the characters, but 
+does not capture the group. A non-capturing group is denoted by a `?` followed by a `:` 
+within parenthesis `(...)`. For example, the regular expression `(?:c|g|p)ar` is similar to 
+`(c|g|p)ar` in that it matches the same characters but will not create a capture group.
+
+
+"(?:c|g|p)ar" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/Rm7Me8/1)
+
+Non-capturing groups can come in handy when used in find-and-replace functionality or 
+when mixed with capturing groups to keep the overview when producing any other kind of output. 
+See also [4. Lookaround](#4-lookaround).
+
+## 2.6 Alternation
+
+In a regular expression, the vertical bar `|` is used to define alternation.
+Alternation is like an OR statement between multiple expressions. Now, you may be
+thinking that character set and alternation works the same way. But the big
+difference between character set and alternation is that character set works on
+character level but alternation works on expression level. For example, the
+regular expression `(T|t)he|car` means: either (uppercase character `T` or lowercase
+`t`, followed by lowercase character `h`, followed by lowercase character `e`) OR
+(lowercase character `c`, followed by lowercase character `a`, followed by
+lowercase character `r`). Note that I put the parentheses for clarity, to show that either expression
+in parentheses can be met and it will match.
+
+
+"(T|t)he|car" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/fBXyX0/1)
+
+## 2.7 Escaping special character
+
+Backslash `\` is used in regular expression to escape the next character. This
+allows us to specify a symbol as a matching character including reserved
+characters `{ } [ ] / \ + * . $ ^ | ?`. To use a special character as a matching
+character prepend `\` before it.
+
+For example, the regular expression `.` is used to match any character except
+newline. Now to match `.` in an input string the regular expression
+`(f|c|m)at\.?` means: lowercase letter `f`, `c` or `m`, followed by lowercase
+character `a`, followed by lowercase letter `t`, followed by optional `.`
+character.
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/DOc5Nu/1)
+
+## 2.8 Anchors
+
+In regular expressions, we use anchors to check if the matching symbol is the
+starting symbol or ending symbol of the input string. Anchors are of two types:
+First type is Caret `^` that check if the matching character is the start
+character of the input and the second type is Dollar `$` that checks if matching
+character is the last character of the input string.
+
+### 2.8.1 Caret
+
+Caret `^` symbol is used to check if matching character is the first character
+of the input string. If we apply the following regular expression `^a` (if a is
+the starting symbol) to input string `abc` it matches `a`. But if we apply
+regular expression `^b` on above input string it does not match anything.
+Because in input string `abc` "b" is not the starting symbol. Let's take a look
+at another regular expression `^(T|t)he` which means: uppercase character `T` or
+lowercase character `t` is the start symbol of the input string, followed by
+lowercase character `h`, followed by lowercase character `e`.
+
+
+"(T|t)he" => The car is parked in the garage.
+

+[Test the regular expression](https://regex101.com/r/5ljjgB/1)

+
+"^(T|t)he" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/jXrKne/1)
+
+### 2.8.2 Dollar
+
+Dollar `$` symbol is used to check if matching character is the last character
+of the input string. For example, regular expression `(at\.)$` means: a
+lowercase character `a`, followed by lowercase character `t`, followed by a `.`
+character and the matcher must be end of the string.
+
+
+"(at\.)" => The fat cat. sat. on the mat.

+
+##  3. Shorthand Character Sets
+
+Regular expression provides shorthands for the commonly used character sets,
+which offer convenient shorthands for commonly used regular expressions. The
+shorthand character sets are as follows:
+
+|Shorthand|Description|
+|:----:|----|
+|.|Any character except new line|
+|\w|Matches alphanumeric characters: `[a-zA-Z0-9_]`|
+|\W|Matches non-alphanumeric characters: `[^\w]`|
+|\d|Matches digit: `[0-9]`|
+|\D|Matches non-digit: `[^\d]`|
+|\s|Matches whitespace character: `[\t\n\f\r\p{Z}]`|
+|\S|Matches non-whitespace character: `[^\s]`|
+
+## 4. Lookaround
+
+Lookbehind and lookahead (also called lookaround) are specific types of
+***non-capturing groups*** (Used to match the pattern but not included in matching
+list). Lookarounds are used when we have the condition that this pattern is
+preceded or followed by another certain pattern. For example, we want to get all
+numbers that are preceded by `$` character from the following input string
+`$4.44 and $10.88`. We will use following regular expression `(?<=\$)[0-9\.]*`
+which means: get all the numbers which contain `.` character and  are preceded
+by `$` character. Following are the lookarounds that are used in regular
+expressions:
+
+|Symbol|Description|
+|:----:|----|
+|?=|Positive Lookahead|
+|?!|Negative Lookahead|
+|?<=|Positive Lookbehind|
+|?
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/IDDARt/1)
+
+### 4.2 Negative Lookahead
+
+Negative lookahead is used when we need to get all matches from input string
+that are not followed by a pattern. Negative lookahead is defined same as we define
+positive lookahead but the only difference is instead of equal `=` character we
+use negation `!` character i.e. `(?!...)`. Let's take a look at the following
+regular expression `(T|t)he(?!\sfat)` which means: get all `The` or `the` words
+from input string that are not followed by the word `fat` precedes by a space
+character.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/V32Npg/1)
+
+### 4.3 Positive Lookbehind
+
+Positive lookbehind is used to get all the matches that are preceded by a
+specific pattern. Positive lookbehind is denoted by `(?<=...)`. For example, the
+regular expression `(?<=(T|t)he\s)(fat|mat)` means: get all `fat` or `mat` words
+from input string that are after the word `The` or `the`.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/avH165/1)
+
+### 4.4 Negative Lookbehind
+
+Negative lookbehind is used to get all the matches that are not preceded by a
+specific pattern. Negative lookbehind is denoted by `(?
+"(?<!(T|t)he\s)(cat)" => The cat sat on cat.

+
+## 5. Flags
+
+Flags are also called modifiers because they modify the output of a regular
+expression. These flags can be used in any order or combination, and are an
+integral part of the RegExp.
+
+|Flag|Description|
+|:----:|----|
+|i|Case insensitive: Sets matching to be case-insensitive.|
+|g|Global Search: Search for a pattern throughout the input string.|
+|m|Multiline: Anchor meta character works on each line.|
+
+### 5.1 Case Insensitive
+
+The `i` modifier is used to perform case-insensitive matching. For example, the
+regular expression `/The/gi` means: uppercase letter `T`, followed by lowercase
+character `h`, followed by character `e`. And at the end of regular expression
+the `i` flag tells the regular expression engine to ignore the case. As you can
+see we also provided `g` flag because we want to search for the pattern in the
+whole input string.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/dpQyf9/1)
+
+
+"/The/gi" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/ahfiuh/1)
+
+### 5.2 Global search
+
+The `g` modifier is used to perform a global match (find all matches rather than
+stopping after the first match). For example, the regular expression`/.(at)/g`
+means: any character except new line, followed by lowercase character `a`,
+followed by lowercase character `t`. Because we provided `g` flag at the end of
+the regular expression now it will find all matches in the input string, not just the first one (which is the default behavior).
+
+
+"/.(at)/" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/jnk6gM/1)
+
+
+"/.(at)/g" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/dO1nef/1)
+
+### 5.3 Multiline
+
+The `m` modifier is used to perform a multi-line match. As we discussed earlier
+anchors `(^, $)` are used to check if pattern is the beginning of the input or
+end of the input string. But if we want that anchors works on each line we use
+`m` flag. For example, the regular expression `/at(.)?$/gm` means: lowercase
+character `a`, followed by lowercase character `t`, optionally anything except
+new line. And because of `m` flag now regular expression engine matches pattern
+at the end of each line in a string.
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/hoGMkP/1)
+
+
+"/.at(.)?$/gm" => The fat
+                  cat sat
+                  on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/E88WE2/1)
+
+## 6. Greedy vs lazy matching
+By default regex will do greedy matching , means it will match as long as
+possible. we can use `?` to match in lazy way means as short as possible
+
+
+"/(.*at)/" => The fat cat sat on the mat.

-## 1. Basic Matchers

-A regular expression is just a pattern of characters that we use to perform
-search in a text.  For example, the regular expression `the` means: the letter
-`t`, followed by the letter `h`, followed by the letter `e`.
+## 1. پایه ای ترین همخوانی
 
+یک عبارت منظم در واقع یک الگو برای جست و جو در یک متن است. برای مثال عبارت منظم  `the` به معنی : حرف
+`t`, پس از آن حرف `h`, پس از آن حرف  `e` است.

 "the" => The fat cat sat on the mat.
 

 
-[Test the regular expression](https://regex101.com/r/dmRygT/1)
 
-The regular expression `123` matches the string `123`. The regular expression is
-matched against an input string by comparing each character in the regular
-expression to each character in the input string, one after another. Regular
-expressions are normally case-sensitive so the regular expression `The` would
-not match the string `the`.

-## 2.5 `(...)` 特征标群
-
 特征标群是一组写在 `(...)` 中的子模式。`(...)` 中包含的内容将会被看成一个整体，和数学中小括号（ ）的作用相同。例如, 表达式 `(ab)*` 匹配连续出现 0 或更多个 `ab`。如果没有使用 `(...)` ，那么表达式 `ab*` 将匹配连续出现 0 或更多个 `b` 。再比如之前说的 `{}` 是用来表示前面一个字符出现指定次数。但如果在 `{}` 前加上特征标群 `(...)` 则表示整个标群内的字符重复 N 次。

 ## What is Regular Expression?

+
+> ביטוי רגולרי (regular expression) הוא קבוצת תוים או סימנים אשר משמשים למציאת תבנית ספציפית בתוך טקסט. 
+
+ביטוי רגולרי הוא תבנית המתאימה את עצמה לנושא במחרוזת משמאל לימין.
+ביטויים רגולרים משמשים להחלפת טקסט בתוך מחרוזת, אימות טפסים,
+חילוץ מחרוזת משנית ממחרוזת ראשית על בסיס התבנית המתאימה, ועוד.
+המונח "Regular expression" (ביטוי רגולרי) הוא יחסית ארוך ולכן בדרך כלל
+נמצא את המונח מקוצר ל-"regex" או "regexp".
+
+תדמיין.י שאת.ה כותב.ת אפליקציה ואת.ה רוצה להציב חוקים למצב בו המשתמש בוחר את
+שם המשתמש. אנחנו רוצים לאפשר לשם המשתמש להכיל אותיות, מספרים, קוים תחתונים ומקפים.
+בנוסף נרצה גם להגביל את מספר התוים בשם המשתמש בכדי שלא יראה מכוער.
+נוכל להשתמש בביטוי הרגולרי הבא בכדי לאמת את שם המשתמש:
+
+


+
+

+  Regular expression
+

+
+הביטוי הרגולרי למעלה יכול לאשר את המחרוזות  `john_doe`, `jo-hn_doe`
+ו-`john12_as`. אך הוא לא יתאים למחרוזת `Jo` בגלל שמחרוזת זו מכילה אות גדולה
+ ובנוסף לכך היא קצרה מדי (פחות משלושה תוים).

+
+## 1. התאמות בסיסיות
+
+ביטוי רגולרי הוא בסף הכל תבנית של תוים שאנו משתמשים בהם בכדי לבצע חיפוש 
+בתוך הטקסט. לדוגמא, הביטוי הרגולרי `the` פירושו: האות `t`, ואחריה האות `h`, ואחריה האות `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/dmRygT/1)
+
+הביטוי הרגולרי `123` מתאים למחרוזת `123`. הביטוי הרגולרי מותאם למחרוזת קלט על ידי השוואת כל תו 
+בביטוי הרגולרי לכל תו במחרוזת הקלט, אחד אחרי השני. ביטויים רגולרים לרוב יהיו 
+תלויי אותיות קטנות או גדולות כך שהביטוי הרגולרי `The` לא יתאים למחרוזת `the`.
+
+
+"The" => The fat cat sat on the mat.

+
+## 2. תווי-מטא
+
+תווי-מטא אלו הם אבני הבניין של ביטויים רגולרים. תווי-מטא לא מסמלים את עצמם, אלא מתפרשים באופן מיוחד.
+לכמה תווי-מטא יש משמעויות מיוחדות והם נכתבים בתוך סוגריים מרובעים.
+תווי-המטא הם כדלקמן: 
+
+|תווי-מטא|תיאור|
+|:----:|----|
+|.|נקודה תואמת כל תו בודד למעט שבירת שורות.|
+|[ ]|מחלקת תווים. תואם כל תו הכלול בין הסוגריים המרובעים.|
+|[^ ]|מחלקת תווים שלילית. תואם כל תו שאינו כלול בין הסוגריים המרובעים|
+|*|תואם 0 או יותר חזרות של הסמל הקודם.|
+|+|תואם חזרה אחת או יותר של הסמל הקודם.|
+|?|הופך את הסמל הקודם לאופציונלי.|
+|{n,m}|סוגריים מסולסלים. תואם לפחות חזרות "n" אך לא יותר מ- "m" של הסמל הקודם.|
+|(xyz)|קבוצת תווים. תואם את התווים xyz בסדר המדויק הזה.|
+|||חלופה (או). התאמה בין התווים שלפני או לתווים שאחרי הסמל.|
+|\|מתעלם מהתו הבא. זה מאפשר לך להתאים תווים שמורים [ ] ( ) { } . * + ? ^ $ \ ||
+|^|תואם את תחילת הקלט.|
+|$|תואם את סוף הקלט.|
+
+## 2.1 עצירה מלאה
+
+עצירה מלאה `.` היר דוגמא פשוטה לשימוש בתו-מטא. תו-המטא `.` מתאים לכל תו בודד. הוא לא יתאים
+לתו return (\r) או לתו newline (\n). למשל, הביטוי הרגולרי `.ar` פירושו: כל תו, שאחריו האות `a`, ואחריה האות `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 מערכות תוים
+
+מערכות תוים נקראים גם מחלקות תוים. סוגריים מרובעים משמשים לציון מערכות תוים.
+השתמש במקף בתוך ערכת התוים בכדי לציין את טווח התוים. סדר טווח התוים לא משנה.
+לדוגמא, הביטוי הרגולרי `[Tt]he` פירושו: אות גדולה
+`T` או אות קטנה `t`, שאחריה מופיעה האות `h`, ואחריה מופיעה האות `e`.
+
+
+"[Tt]he" => The car parked in the garage.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/2ITLQ4/1)
+
+נקודה בתוך ערכת התוים בשונה מבחוץ תחשב כתו נקודה. הביטוי הרגולרי 
+`ar[.]` פירושו: תו האות הקטנה `a`, שאחריו האות `r`,
+ואחריה התו נקודה `.`.
+
+
+"ar[.]" => A garage is a good place to park a car.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/wL3xtE/1)
+
+### 2.2.1 מערכות תוים שליליות 
+
+באופן כללי, הסימן "קרט"(גג) מייצג את תחילתה של מחרוזת, אך במידה והוא מוקלד לאחר סוגר מרובע פותח,
+הוא שולל את מערכת ההתוים שיהיו תחת אותם סוגרים. לדוגמא, הביטוי הרגולרי `[^c]ar` פירושו: כל תו חוץ מ-`c`,
+שלאחריו יופיע התו `a`, שאחריו יופיע התו `r`.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/nNNlq3/1)
+
+## 2.3 חזרות
+
+תווי-המטא `+`, `*` או `?` משמשים לציון כמה פעמים דפוסי משני יכולים להתרחש.
+תווי-מטא אלו פועלים אחרת במצבים שונים.
+
+### 2.3.1 הכוכבית
+
+הסימן - `*` תואם אפס או יותר חזרות של המתאם הקודם. הביטוי הרגולרי `a*` פירושו: 
+אפס או יותר חזרות של התו הקודם- `a`. אבל אם הכוכבית תופיע לאחר מערכת או מערך תוים אז
+הוא ימצא את החזרות של מערכת התוים כולה. לדוגמא, הביטוי הרגולרי `[a-z]*` פירושו: 
+כל מספר של אותיות קטנות בשורה.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/7m8me5/1)
+
+הסימן - `*` יכול לשמש יחד עם התו-מטא `.` בכדי להתאים כל מחרוזת תוים `.*`.
+הסימון - `*` יכול לשמש יחד עם התו רווח - `\s` בכדי להתאים מחרוזת של תוי רווח.
+לדוגמא, הביטוי `\s*cat\s*` פירושו: אפס או יותר רווחים, שאחריהם תופיעה האות הקטנה `c`,
+שאחריה תופיע האות הקטנה `a`, ואחריה האות הקטנה `t`, ולבסוף אחריה יופיעו אפס או יותר תווי רווח.
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/gGrwuz/1)
+
+### 2.3.2 הפלוס
+
+הסימן `+` מתאים לאחת או יותר חזרות של התו הקודם לו. לדוגמא, הביטוי הרגולרי
+ `c.+t` פירושו: האות הקטנה - `c`, לאחריה לפחות תו אחד או יותר,
+  ואחריה האות הקטנה  `t`. חשוב לציין שה - `t` יהיה התו `t` האחרון במשפט.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 סימן השאלה
+
+בביטוי רגולרי, התו-מטא `?` הופך את התו הקודם לאופציונלי, 
+סמל זה יתאים לאפס או יותר הופעות של אותו תו קודם. לדוגמא, הביטוי הרגולרי 
+`[T]?he` פירושו: אופציה לאות
+`T` גדולה, ולאחריה אות קטנה `h`, ולאחריה תופיע האות - `e`.
+
+
+"[T]he" => The car is parked in the garage.

+
+## 2.4 סוגרים מסולסלים
+
+בביטויים רגולרים, סוגרים מסולסלים (נקראים גם מכמתים) משמשים לציון
+מספר הפעמים שניתן לחזור על תו או קבוצת תוים מסויימת. לדוגמא, הביטור הרגולרי
+ `[0-9]{2,3}` פירושו: התאם לפחות שתי ספרות, אבל לא יותר משלוש, בטווח שבין 0 ל-9
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/juM86s/1)
+
+אנחנו יכולים לוותר על המספר השני בסוגרים המסולסלים. לדוגמא, בביטוי הרגולרי 
+`[0-9]{2,}` פירושו: התאמת שתי ספרות או יותר. בנוסף אם 
+נוריד את הפסיק, לדוגמא בביטוי הרגולרי `[0-9]{3}` פירושו: 
+התאם בדיוק שלוש ספרות.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/Gdy4w5/1)

+
+## 2.5 קבוצות לכידה
+
+קבוצה מלכדת היא קבוצה של תת-תבניות שנכתבות בתוך סוגריים רגילים  `(...)` . 
+כפי שצויין קודם לכן, בביטוי רגולרי, אם נניח מכמת אחרי תו הוא יחזור על התו הקודם. 
+אבל אם נניח מכמת אחרי קבוצה מלכדת אז המכמת יתיחס לכל הקבוצה המלכדת. לדוגמא, הביטוי הרגולרי 
+`(ab)*` תואם אפס או יותר חזרות של המחרוזת "ab". אנחנו יכולים גם להשתמש 
+בתו-מטא `|` המשמש לבצע את הפעולה 'OR'(או) בתוך קבוצה מלכדת.
+לדוגמא, הביטוי הרגולרי `(c|g|p)ar` פירושו: אות קטנה `c`,
+`g` או `p`, שאחריהן תופיע האות `a`, ואחריה האות `r`.
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/tUxrBG/1)
+
+יש לשים לב כי קבוצות מלכדות לא רק תואמות, אלא גם תופסות את התוים לשימוש בשפת האם. 
+שפת האם יכולה להיות Python או JavaScript או כמעט כל שפה שמיישמת ביטויים רגולרים 
+בבגדרת פונקציה.
+
+### 2.5.1 קבוצות שאינן לוכדות
+
+קבוצה שאינה מלכדת זוהי קבוצת לוכדת התואמת את התוים אבל לא תופסת את הקבוצה.
+קבוצה שאינה מלכדת מסומנת על ידי התו `?` ואחריו `:` בתוך הסוגריים הרגילים. `(...)`. 
+לדוגמא, בביטוי הרגולרי `(?:c|g|p)ar` שדומה ל-`(c|g|p)ar` 
+בכך שהוא תואם לאותם תווים אך לא ייצר קבוצת לכידה.
+
+
+"(?:c|g|p)ar" => The car is parked in the garage.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/Rm7Me8/1)
+
+קבוצות שאינן מלכדות יכולות להיות שימושיות כאשר יש צורך בפונקציונליות של חיפוש והחלפה
+או כאשר מעורבת גם קבוצת לכידה בכדי לשמור על הסקירה כאשר מפיקים כל סוג אחר של פלט. 
+ניתן לראות גם ב [4. Lookaround](#4-lookaround).
+
+## 2.6 חלופה
+
+בביטוי רגולרי, הקו ניצב `|` משמש בכדי להגדיר חלופה. חלופה היא כמו הצהרת OR (או) 
+בין ביטויים שונים. כעט את.ה עלול לחשוב שמערכות התווים והתו המשמש להגדרת חלופה יעבדו באותה הדרך. 
+אך ההבדל העיקרי בין מערכת תווים לבין חלופה הוא שמערכת תווים פועלת ברמת התו והחלופה
+עובדת ברמת הביטוי. לדוגמא, הביטוי הרגולרי `(T|t)he|car` פירושו: או (אות גדולה `T` או אות קטנה
+`t`, שלאחריהן אות קטנה `h`, שאחריה אות קטנה `e`) או (אות קטנה `c`, שאחריה תופיע האות `a`, 
+ולאחריה תופיע האות `r`). יש לשים לב שהכללתי את הסוגריים לשם ההבהרה, 
+בכדי להראות שאפשר להתמודד עם כל ביטוי בסוגריים והוא יתאים. 
+
+
+"(T|t)he|car" => The car is parked in the garage.

+
+## 2.7 התעלמות מתווים מיוחדים
+
+לוכסן שמאלי `\` משמש בביטוי רגולרי בכדי להתעלם מהתו הבא. זה מאפשר לנו לכלול תוים שמורים כמו 
+`{ } [ ] / \ + * . $ ^ | ?` כתוים להתאמות. הכדי להשתמש בתוים המיוחדים הללו התו התאמה, 
+יש להוסיף אותו מראש עם `\` לפניו. לדוגמא, הביטוי הרגולרי `.` משמש בכדי להתאים כל תו חוץ משורה חדשה. 
+כעט בכדי לבצע התאמה עם הסימן `.` במחרוזת קלט, יהיה צורך בהוספת הלוכסן השמאלי. למשל בביטוי הרגולרי 
+`(f|c|m)at\.?` פירושו: אות קטנה `f`, `c` או `m`, שאחריהן תופיע האות הקטנה
+`a`, ואחריה תופיע האות הקטנה `t`, ולבסוף יופיע באופן אופציונלי התו - `.`.
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.

+
+## 2.8 עוגנים
+
+בביטויים רגולרים, אנחנו משתמשים בעוגנים בכדי לבדוק אם סימן ההתאמה הוא סימן התחלה או 
+סימן סיום של מחרוזת הקלט. ישנם שני סוגי עוגנים: 
+הסוג הראשון הוא ה"קרט"(גג) `^` שבודק אם תו תואם הוא התו הראשון של הקלט והסוג השני הוא סימן הדולר 
+`$` אשר בודק אם תו תואם הוא התו האחרון שבקלט
+
+### 2.8.1 ה-"קרט"
+
+הסימן "קרט" `^` משמש לבדיקה אם תו תואם הוא התו הראשון של מחרוזת הקלט. 
+אם ניישם את הביטור הרגולרי הבא `^a` (כלומר 'a' חייב להיות התו ההתחלתי) 
+המחרוזת `abc`, תתאים לדרישות `a`. 
+אך אם ניישם את הביטוי הרגולרי `^b` על במחרוזת למעלה, היא לא תמצא אף התאמה. 
+בגלל שבמחרוזת `abc`, ה-"b" אינו תו התחלתי. בואו נסתכל על ביטוי רגולרי אחר 
+`^(T|t)he` שפירושו: אות גדולה `T` או אות קטנה `t` חייבת להיות התו הראשון של המחרוזת, 
+ואחריה האות הקטנה `h`, ולאחריה האות הקטנה `e`.

+
+### 2.8.2 סימן הדולר
+
+סימן הדולר `$` משמש בכדי לבדוק אם התו התואם הוא התו האחרון במחרוזת. לדוגמא, 
+הביטוי הרגולרי `(at\.)$` פירושו: האות הקטנה `a`, שאחריה תיהיה האות הקטנה `t`, ואחריה התו נקודה `.`
+וכל ההתאמה חייבת לביות בסופה של המחרוזת.

+
+##  3. קיצורי מערכות תווים
+
+ישנם מספר קיצורים נוחים למערכות תווים נפוצות / ביטויים רגולרים: 
+
+|קיצור|תיאור|
+|:----:|----|
+|.|תואם כל תו חוץ מתחילת שורה חדשה|
+|\w|תואם תוים אלפא-נומריים (אותיות ומספרים): `[a-zA-Z0-9_]`|
+|\W|תואם תוים לא אלפא-נומריים: `[^\w]`|
+|\d|תואם ספרות: `[0-9]`|
+|\D|תואם תוים שאינם ספרות: `[^\d]`|
+|\s|תואם תוי רווח: `[\t\n\f\r\p{Z}]`|
+|\S|תואם תוים שאינם רווח: `[^\s]`|
+
+## 4. הסתכלויות
+
+מבט לאחור ומבט לפנים (נקראים גם הסתכלויות) אלו הם סוגים ספציפים של קבוצות שאינן לוכדות. 
+(משמשות בכדי להתאים תבנית אך ללא הכנסתה לרשימת ההתאמות).
+הסתכלויות משמשות כאשר יש להקדים תבנית בכך שזו תלויה בתבנית אחרת בכדי שהראשונה תתאים. 
+לדוגמא, תדמיין.י שאנחנו רוצים לקבל את כל המספרים שלפניהם יש את התו `$` מהמחרוזת 
+`$4.44 and $10.88`. אנחנו נשתמש בביטוי הרגולרי הבא: 
+`(?<=\$)[0-9\.]*` שפירושו: התאם את כל הספרות או התו `.` שלפני ההתאמה 
+קיים התו `$`. בטבלה מטה מוצגים סוגי המבטים המשמשים ביטויים רגולרים: 
+
+|סימן|תיאור|
+|:----:|----|
+|?=|מבט קדימה חיובי|
+|?!|מבט קדימה שלילי|
+|?<=|מבט אחורה חיובי|
+|?|מבט אחורה שלילי|
+
+### 4.1 מבט קדימה חיובי
+
+מבט קדימה חיובי דורש שבחלקו הראשון של ביטוי חייב להתקיים הביטוי מבט קדימה חיובי. 
+ההתאמה המוחזרת מכילה רק את הטקסט המתאים לחלק הראשון של הביטוי לפני המבט קדימה. 
+בכדי להגדיר מבט קדימה חיובי, משתמשים בסוגריים. בתוך הסוגריים, משתמשים בסימן שאלה 
+ואחריו סימן השוואה כך: `(?=...)`. ביטויי המבט קדימה נכתבים אחרי סימני סוג 
+המבט בתוך הסוגריים. לדוגמא, הביטוי הרגולרי `(T|t)he(?=\sfat)` פירושו: 
+התאם או את האות הקטנה `t` או את האות הגדולה `T`, שאחריה תיהיה האות `h`, ואחריה האות `e`. 
+בסוגריים אנחנו מגדירים מבט קדימה חיובי שאומר למנוע של הביטוי הרגולרי להתאים `The` או `the` 
+רק אם אחרי ההתאמה מופיעה המחרוזתS ` fat`.
+
+
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/IDDARt/1)
+
+### 4.2 מבט קדימה שלילי
+
+משתמשים במבט קדימה שלילי כשאנחנו צריכים לקבל את כל ההתאמות ממחרוזת קלט שלאחריהן אין תבנית מסויימת. 
+מבט קדימה שלילי יכתב באותה הדרך כמו שנכתב המבט קדימה החיובי. ההבדל היחיד הוא שמבקום 
+סימן השווה `=`, עלינו להשתמש בסימן קריאה `!` בכדי לציין את השלילה כלומר: `(?!...)`. 
+בואו נסתכל על הביטוי הרגולרי הבא `(T|t)he(?!\sfat)` שפירושו: התאם את כל המילים `The` או `the` 
+ממחרוזת קלט שאחריהן אין את התו רווח ולאחר מכן את המילה `fat`.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/V32Npg/1)
+
+### 4.3 מבט אחורה חיובי
+
+משתמשים במבט אחורה חיובי בכדי לקבל את כל ההתאמות שלפניהן יש תבנית ספציפית מסויימת. 
+מבטים אחורה חיוביים נכתבים כך: `(?<=...)`. לדוגמא, 
+הביטוי הרגולרי `(?<=(T|t)he\s)(fat|mat)` פירושו: התאם 
+את כל המילים `fat` או `mat` ממחרוזת קלט שנמצאות לפני המילים `The` או `the` ויש רווח 
+שמפריד בינהן.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.
+

+
+### 4.4 מבט אחורה שלילי
+
+משתמשים במבט אחורה שלילי בכדי לקבל את כל ההתאמות שלפניהן אין תבנית ספציפית מסויימת.
+מבטים אחורה שליליים יכתבו כך: `(?. לדוגמא, הביטוי הרגולרי 
+`(? פירושו: התאם את כל המילים `cat` 
+ממחרוזת קלט שלא נמצאות אחרי המילים `The` or `the` כאשר רווח מפריד בינהן.
+
+
+"(?<!(T|t)he\s)(cat)" => The cat sat on cat.

+
+## 5. דגלים
+
+דגלים נקראים גם משנים בגלל שהם משנים את הפלט של הביטוי הרגולרי. 
+ניתן להשתמש בדגלים הללו בכל סדר או שילוב והם חלק בלתי נפרד 
+מהביטוי הרולרי (RegExp).
+
+|דגל|תיאור|
+|:----:|----|
+|i|חוסר רגישות לאותיות: ההתאמה לא תהיה רגישה לאותיות קטנות או גדולות.|
+|g|חיפוש גלובלי: התאם את כל ההאמות שהופיעו, לא רק את הראשונה.|
+|m|רב-שורות: תווי-המטא העוגנים (`$` או `^`) עובדים על כל שורה.|
+
+### 5.1 חוסר רגישות לאותיות
+
+המשנה `i` משמש בכדי לבצע התאמות חסרות רגישות לאותיות קטנות או גדולות.
+לדוגמא, בביטוי הרגולרי `/The/gi` פירושו: אות גדולה `T`, ואחריה אות קטנה
+`h`, ואחריה אות קטנה `e`. ובסוף הביטוי הרגולרי יש את הדגל `i` שאומר למנוע הביטוי הרגולרי 
+להתעלם מהבדלי אותיות גדולות או קטנות. וכפי שאת.ה יכול לראות,
+סיפקנו גם דגל `g` בגדלל שאנחנו רוצים לחפש את התבנית בכל מחרוזת הקלט. 
+
+
+"The" => The fat cat sat on the mat.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/dpQyf9/1)

+"/The/gi" => The fat cat sat on the mat.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/ahfiuh/1)
+
+### 5.2 חיפוש גלובלי
+
+המשנה `g` משמש בכדי לבצע התאמות גלובליות (מוצא את כל ההתאמות במקום לעצור בהתאמה הראשונה). 
+לדוגמא, בביטוי הרגולרי `/.(at)/g` פירושו: כל תו חות משורה חדשה, שאחריו תיהיה האות הקטנה `a`,
+ואחריה תיהיה האות הקטנה `t`. בגלל שסיפקנו את הדגל `g` בסופו של הביטוי הרגולרי, 
+הוא עכשיו ימצא את כל ההתאמות במחרוזת הקלט, לא רק את ההתאמה הראשונה (שזו התנהגות ברירת המחדל).
+
+
+"/.(at)/" => The fat cat sat on the mat.
+

+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/jnk6gM/1)
+
+
+"/.(at)/g" => The fat cat sat on the mat.
+

+
+[בדוק.י את הביטוי הרגולרי](https://regex101.com/r/dO1nef/1)
+
+### 5.3 רב-שורות
+
+המשנה `m` משמש בכדי לבצע התאמות במספר רב של שורות. כפי שדנו על כך קודם לכן, 
+העוגנים `(^, $)` משמשים לבדיקה אם תבנית היא בהתחלה או בסופו של קלט. 
+אבל אם אנחנו רוצים שהעוגנים הללו יעבדו על כל שורה, אנחנו נשתמש בדגל `m`. לדוגמא, 
+בביטוי הרגולרי `/at(.)?$/gm` פירושו: אות קטנה
+`a`, שלאחריה האות הקטנה `t` וכאופציה, כל תו שאינו שורה חדשה. ובגלל הדגל `m`, 
+המנוע של הביטוי הרגולרי יתאים את התבנית בכל סוף שורה במחרוזת. 
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.
+

+
+## 6. התאמה חמדנית מול עצלה
+
+כברירת מחדל, ביטוי רגולרי יבצע התאמה חמדנית, זאת אומרת שביצוע ההתאמה תיהיה ארוכה ככל הניתן. 
+אנחנו יכולים להשתמש ב-`?` בכדי לבצע התאמה בצורה עצלה, פירוש הדבר שההתאמה תיהיה קצרה ככל שניתן.

+
+> Un'espressione regolare è un insieme di caratteri e simboli utilizzati per trovare una specifica sequenza (pattern) di testo.
+
+
+Un'espressione regolare è una sequenza che corrisponde a una stringa di testo letta da sinistra a destra. Le espressioni regolari sono utilizzate per sostituire parti di testo in una stringa, validare moduli, estrarre parti di stringhe basate sulla corrispondenza di uno schema e molto altro. Il termine "Espressione regolare" è molto lungo quindi è normalmente abbreviato con "regex" o "regexp".
+
+Immagina che stai scrivendo un applicazione e hai bisogno di impostare una regola per quando un utente sceglie il suo nome utente. Vogliamo consentire che il nome utente contenga lettere, numeri, carattere di sottolineo e il trattino, vogliamo inoltre limitare il numero di caratteri del nome utente. Possiamo utilizzare la seguente espressione regolare per validare il nome utente:
+


+

+  Regular expression
+

+
+L'espressione regolare riportata sopra può accettare le stringhe `john_doe`, `jo-hn_doe` e `john12_as`. Non c'è corrispondenza con `Jo` perché contiene una lettera maiuscola ed inoltre è troppo breve.

+## 1. Corrispondenze di base
+
+Un'espressione regolare non è altro che una sequenza di caratteri usati per eseguire ricerche in un testo. Ad esempio, l'espressione regolare `the` corrisponde a: la lettera `t`, seguita dalla lettera `h`, seguita dalla lettera `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/dmRygT/1)
+
+L'espressione regolare `123` corrisponde alla stringa `123`. L'espressione regolare viene confrontata con il testo da ricercare carattere per carattere, al fine di trovare la corrispondenza completa.
+Le espressioni regolari sono normalmente sensibili a caratteri maiuscoli e minuscoli, perciò l'espressione regolare `The` non troverà corrispondenza con il testo `the`.
+
+
+"The" => The fat cat sat on the mat.
+

+
+## 2. Caratteri jolly
+
+I caratteri jolly sono i mattoncini per la costruzione di espressioni regolari. I caratteri jolly non vengono usati letteralmente, vengono invece interpretati come caratteri speciali. Alcuni caratteri jolly hanno un significato speciale se inseriti all'interno di parentesi quadre. I caratteri jolly sono i seguenti:
+
+|Carattere jolly|Descrizione|
+|:----:|----|
+|.|Il punto corrisponde ad ogni carattere eccetto l'invio e l'interruzione di riga.|
+|[ ]|Classe di caratteri. Corrispondenza con ciascun carattere contenuto tra le parentesi.|
+|[^ ]|Negazione di classe di caratteri. Corrispondenza con ciascun carattere non contenuto all'interno delle parentesi|
+|*|Corrispondenza con zero o più ripetizioni del carattere che lo precede.|
+|+|Corrispondenza con una o più ripetizioni del carattere che lo precede|
+|?|Rende opzionale il carattere che lo precede.|
+|{n,m}|Parentesi graffe. Corrisponde con le ripetizione minima di "n" ma non più di "m", del carattere che le precede.|
+|(xyz)|Gruppo di caratteri. Corrispondenza con i caratteri tra parentesi xyz solo nell'ordine esatto.|
+|||Alternativa. Corrispondenza con il carattere che precede o con quello che segue.|
+|\|Escape sul carattere successivo. Consente la corrispondenza con i caratteri riservati [ ] ( ) { } . * + ? ^ $ \ ||
+|^|Corrispondenza con l'inizio del testo.|
+|$|Corrispondenza con la fine del testo.|
+
+## 2.1 Il punto
+
+Il punto `.` è il più semplice esempio di carattere jolly. Il carattere jolly `.` ha corrispondenza con ogni singolo carattere nel testo da cercare. Non ha corrispondenza con i caratteri di invio e fine riga.
+Ad esempio, l'espressione regolare `.ar` significa: ciascun carattere, seguito dalla lettera `a`, seguita dalla lettera `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 Classi di carattere
+
+Le parentesi quadre sono utilizzate per definire una classe di caratteri. Si può utilizzare il trattino per definire degli intervalli all'interno della classe. L'ordine dei caratteri utilizzati nella classe non ha influenza sul risultato. Ad esempio, l'espressione regolare `[Tt]he` significa: una lettera maiuscola `T` o una lettera minuscola `t`, seguita dalla lettera `h`, seguita dalla lettera `e`.
+
+
+"[Tt]he" => The car parked in the garage.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/2ITLQ4/1)
+
+Un punto all'interno di una classe di caratteri, in ogni caso, corrisponde al punto letterale. L'espressione regolare `ar[.]` corrisponde a: una lettera minuscola `a`, seguita dalla lettera `r`, seguita dal carattere `.`.
+
+
+"ar[.]" => A garage is a good place to park a car.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/wL3xtE/1)
+
+### 2.2.1 Negazione di classe di carattere
+
+In generale, il carattere di omissione ^ rappresenta l'inizio di un testo, ma se inserito come primo carattere all'interno di parentesi quadre, funziona come negazione della classe di caratteri. Ad esempio, l'espressione regolare `[^c]ar` corrisponde a: qualsiasi carattere tranne la lettera `c`, seguito dalla lettera `a`, seguita dalla lettera `r`.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/nNNlq3/1)
+
+## 2.3 Ripetizioni
+
+I caratteri jolly `+`, `*` o `?` sono utilizzati per specificare quante volte uno schema si può ripetere. Questi caratteri jolly agiscono in modo differente per differenti situazioni.
+
+### 2.3.1 Simbolo Asterisco
+
+Il simbolo `*` corrisponde a zero o più ripetizioni della sequenza precedente. L'espressione regolare `a*` corrisponde a: zero o più ripetizioni della precedente lettera minuscola `a`.
+Se il simbolo viene utilizzato a seguito di una classe di caratteri allora verranno applicate le ripetizioni all'intera classe. Ad esempio, l'espressione regolare `[a-z]*` corrisponde a: qualsiasi ripetizione di ciascuna lettera minuscola in un testo.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/7m8me5/1)
+
+Il simbolo `*` più essere applicato al carattere jolly `.` per la corrispondenza con qualsiasi numero di caratteri `.*`. Il simbolo `*` può essere usato con lo spazio vuoto `\s` per la corrispondenza con una stringa di spazi vuoti. Ad esempio l'espressione regolare `\s*cat\s*` corrisponde a: nessuno o più spazi, seguiti dalla lettera minuscola `c`, seguita dalla lettera minuscola `a`, seguita dalla lettera minuscola `t`, seguite da nessuno o più spazi vuoti.
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/gGrwuz/1)
+
+### 2.3.2 Simbolo Più
+
+Il simbolo `+` corrisponde a una o più ripetizioni della sequenza precedente. Ad esempio, l'espressione regolare `c.+t` corrisponde a: una lettera minuscola `c`, seguita da almeno un carattere, seguito dalla lettera minuscola `t`. 
+È importante chiarire che `t` corrisponde all'ultima lettera `t` nella stringa.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 Carattere Punto di Domanda
+
+Nelle espressioni regolari, il carattere jolly `?` rende opzionale il carattere che lo precede. Questo simbolo corrisponde alla ripetizione zero o una volta della sequenza che lo precede.
+Ad esempio, l'espressione regolare `[T]?he` corrisponde a: Lettera maiuscola opzionale `T`, seguita, se presente, dalla lettera maiuscola `h`, seguita dalla lettera minuscola `e`.
+
+
+"[T]he" => The car is parked in the garage.
+

+
+
+"[T]?he" => The car is parked in the garage.

+
+## 2.4 Parentesi graffe
+
+Nelle espressioni regolari, le parentesi graffe (chiamate anche quantificatori) sono utilizzate per specificare il numero di volte che un carattere o una classe di caratteri possono essere ripetute per mantenere la corrispondenza. Ad esempio, l'espressione regolare `[0-9]{2,3}` corrisponde a: Almeno 2 cifre, ma non più di 3, nell'intervallo da 0 a 9.
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/juM86s/1)
+
+Si può omettere il secondo numero. Ad esempio, l'espressione regolare `[0-9]{2,}` corrisponde a: 2 o più cifre. Inoltre possiamo rimuove la virgola di separazione, l'espressione regolare `[0-9]{3}` corrisponde a: esattamente 3 cifre.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+

+
+[Verifica l'espressione regolare](https://regex101.com/r/Sivu30/1)
+
+## 2.5 Raggruppamento e cattura di caratteri
+
+Un gruppo di caratteri è un sottoschema scritto all'interno di parentesi `(...)`. Come esposto in precedenza, se inseriamo un quantificatore a seguito di un carattere, viene definita la ripetizione del carattere stesso; allo stesso modo, se inseriamo un quantificatore a seguito di un gruppo di caratteri, definiamo la ripetizione dell'intero gruppo. Ad esempio, l'espressione regolare `(ab)*` corrisponde a zero o più ripetizioni della sequenza esatta di lettere minuscole "ab". 
+Si può inoltre utilizzare il carattere di alternativa `|` all'interno di un gruppo di caratteri.
+Ad esempio, l'espressione regolare `(c|g|p)ar` corrisponde a: una lettera minuscola a scelta tra `c`, `g` o `p`, seguita dalla lettera minuscola `a`, seguite dalla lettera minuscola `r`.
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/tUxrBG/1)
+
+Nota che il gruppo di carattere non trova solo corrispondenza, ma cattura il contenuto del gruppo, per utilizzarlo in un linguaggio di programmazione. Il linguaggio può essere Python, Javascript o qualsiasi linguaggio che implementi funzioni per l'utilizzo di espressioni regolari.
+
+### 2.5.1 Raggruppamento di caratteri senza cattura
+
+Un gruppo di caratteri senza cattura è un gruppo utilizzato per la corrispondenza ma non per la cattura. È definito dal carattere `?` seguito da `:` all'interno delle parentesi `(...)`. Ad esempio, l'espressione regolare `(?:c|g|p)ar` è simile a `(c|g|p)ar`, corrisponde alla stessa stringa ma non cattura il gruppo.
+
+
+"(?:c|g|p)ar" => The car is parked in the garage.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/Rm7Me8/1)
+
+I gruppi senza cattura sono utili per funzioni di ricerca e sostituzione o quando utilizzati in abbinata con gruppi di cattura per produrre diversi tipi di output.
+Vedere anche [4. Guardarsi intorno](#4-lookaround).
+
+## 2.6 Alternativa
+
+In un'espressione regolare, la barra verticale `|` è utilizzata per definire alternative.
+L'alternativa corrisponde alla dichiarazione OR tra espressioni multiple. Sagrai pensando che gli insiemi di caratteri e le alternative funzionino allo stesso modo, ma la grande differenza è che l'alternativa funziona a livello di espressione. Ad esempio, l'espressione regolare `(T|t)he|car` corrisponde a: sia (una lettera maiuscola `T` o una lettera minuscola `t`, seguita dalla lettera minuscola `h`, seguita da una lettera minuscola `e`), sia
+(Una lettera minuscola `c`, seguita da una lettera minuscola `a`, seguita dalla lettera minuscola `r`).
+Nota che sono state incluse le parentesi per chiarezza, per dimostrare come le espressioni possono funzionare anche all'interno delle parentesi stesse.
+
+
+"(T|t)he|car" => The car is parked in the garage.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/fBXyX0/1)
+
+## 2.7 Carattere speciale Escape
+
+Il carattere di escape `\` è utilizzato nelle espressioni regolari per annullare la funzione del carattere jolly seguente. Questo consente di includere caratteri riservati, come `{ } [ ] / \ + * . $ ^ | ?` all'interno di un'espressione regolare per la corrispondenza letterale.
+
+Ad esempio, l'espressione regolare `.` è utilizzata per la corrispondenza con qualsiasi carattere eccetto il carattere di invio e di fine riga. Quindi, per la corrispondenza del carattere `.`, l'espressione regolare `(f|c|m)at\.?` corrisponde a: una lettera minuscola `f`, `c` o `m`, seguita dalla lettera minuscola `a`, seguita dalla lettera minuscola `t`, seguita dal carattere `.` opzionale.
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/DOc5Nu/1)
+
+## 2.8 Ancore
+
+Nelle espressioni regolari, si usano le ancore per la corrispondenza dell'espressione stessa, all'inizio o al termine di un testo.
+Le ancora sono di due tipi:
+Il primo tipo è il carattere di negazione `^`  che verifica la corrispondenza all'inizio del testo, il secondo tipo è il carattere `$` che verifica la corrispondenza al termine del testo.
+
+### 2.8.1 Il carattere di negazione ^
+
+Il simbolo di negazione `^` è usato per verificare la corrispondenza al primo carattere del testo. Utilizzando l'espressione regolare `^a` (significa che 'a' deve essere il primo carattere) con il testo `abc`, ci sarà corrispondenza con `a`. Applicando l'espressione regolare `^b` al testo precedente, non ci sarà alcuna corrispondenza.
+Questo perché nel testo `abc`, la lettera "b" non è il carattere iniziale. Vediamo un'altra espressione regolare, `^(T|t)he` che corrisponde a: una lettera maiuscola `T` o una lettera minuscola `t` deve essere la prima lettera del testo, seguita dalla lettera minuscola `h`, seguita dalla lettera minuscola `e`.
+
+
+"(T|t)he" => The car is parked in the garage.

+
+### 2.8.2 Il simbolo del Dollaro
+
+Il simbolo del collario `$` è utilizzato per verificare la corrispondenza con la parte finale del testo. Ad esempio, l'espressione regolare `(at\.)$` corrisponde a: una lettera minuscola `a`, seguita da una lettera minuscola `t`, seguita dal carattere punto `.`, il tutto deve trovarsi al termine del testo.
+
+
+"(at\.)" => The fat cat. sat. on the mat.

+
+##  3. Classe di caratteri rapide
+
+Ci sono alcune classe di caratteri rapide per l'utilizzo nelle espressioni regolari:
+
+|Classe di caratteri rapide|Descrizione|
+|:----:|----|
+|.|Qualsiasi carattere tranne invio e fine riga|
+|\w|Corrispondenza con caratteri alfanumerici: `[a-zA-Z0-9_]`|
+|\W|Corrispondenza con caratteri non alfanumerici: `[^\w]`|
+|\d|Corrispondenza con numeri: `[0-9]`|
+|\D|Corrispondenza con caratteri che non siano numeri: `[^\d]`|
+|\s|Corrispondenza con spazi vuoti: `[\t\n\f\r\p{Z}]`|
+|\S|Corrispondenza con caratteri che non siano spazi vuoti: `[^\s]`|
+
+## 4. Guardarsi intorno
+
+Lookbehinds e lookaheads sono speciali tipi di ***gruppi di caratteri senza cattura***. Guardarsi intorno sono utilizzati quando uno schema deve essere preceduto o seguito da un altro schema. Ad esempio, pensiamo di dover selezionare i numeri preceduti dal carattere `$` nel testo `$4.44 and $10.88`. Useremo l'espressione regolare `(?<=\$)[0-9\.]*` che corrisponde a: selezionare tutti i numeri che contengono il carattere `.` e sono preceduti dal carattere `$`. Queste sono le espressioni di guardarsi intorno utilizzate:
+
+|Simbolo|Descrizione|
+|:----:|----|
+|?=|Lookahead positivo|
+|?!|Lookahead negativo|
+|?<=|Lookbehind positivo|
+|?
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/IDDARt/1)
+
+### 4.2 Lookahead negativo
+
+Lookahead negativo è utilizzato per ottenere corrispondenza con una stringa che non è seguita da un determinato schema. Il lookahead negativo è scritto nello stesso modo del lookahead positivo. L'unica differenza consiste nell'utilizzo del carattere di punto esclamativo `!`, al posto del segno uguale `=`, per indicare la negazione, ad esempio `(?!...)`. Vediamo la seguente espressioni regolare `(T|t)he(?!\sfat)` che trova corrispondenza con: tutte le parole `The` o `the` che non sono seguite da uno spazio dalla parola `fat`.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/V32Npg/1)
+
+### 4.3 Lookbehind positivo
+
+Lookbehind positivo è utilizzato per trovare il testo preceduto da uno specifico schema. Il lookbehind positivo è sxcritto come `(?<=...)`. Ad esempio, l'espressione regolare `(?<=(T|t)he\s)(fat|mat)` corrisponde a: tutte le parole `fat` o `mat` che seguono la parola `The` o `the`.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/avH165/1)
+
+### 4.4 Lookbehind negativo
+
+Lookbehind negativo è utilizzato per trovare il testo non preceduto da uno specifico schema. Il lookbehind negativo è sxcritto come `(?
+"(?<!(T|t)he\s)(cat)" => The cat sat on cat.

+
+## 5. Opzioni
+
+Le opzioni (o modificatori) modificano il risultato delle espressioni regolari. Queste opzioni possono essere utilizzate in qualsiasi ordine o combinazione, sono parti integranti di RegExp.
+
+|Opzione|Descrizione|
+|:----:|----|
+|i|Non sensibilità maiuscolo / minuscolo|
+|g|Ricerca globale: trova tutte le corrispondenze, non solo la prima.|
+|m|Multi riga: estende il funzionamento delle ancore su ogni riga.|
+
+### 5.1 Non sensibilità maiuscolo / minuscolo
+
+L'opzione `i` è usato per rendere la corrispondenza non sensibile a maiuscolo / minuscolo. Ad esempio, l'espressione regolare `/The/gi` corrisponde a: una lettera maiuscola `T`, seguita da una lettera minuscola `h`, seguita da una lettera minuscola `e`. L'opzione `i` alla fine dell'espressione regolare indica di ignorare minuscole / maiuscole. Come si può notare, l'utilizzo dell'opzione `g` estende la ricerca all'intero testo.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Verifica l'espressione regolare](https://regex101.com/r/dpQyf9/1)

+
+### 5.2 Ricerca globale
+
+L'opzione `g` è utilizzata per estendere la ricerca a corrispondenze multiple. Ad esempio, l'espressione regolare `/.(at)/g` corrisponde a: qualsiasi carattere eccetto invio e nuova riga, seguito dalla lettera minuscola `a`, seguita dalla lettera minuscola `t`. L'utilizzo dell'opzione `g` estende la ricerca all'intero testo.
+
+
+"/.(at)/" => The fat cat sat on the mat.

+
+### 5.3 Multi riga
+
+L'opzione `m` è utilizzata per estendere la corrispondenza in modalità multi riga. Come già esposto, le ancore `(^, $)` sono utilizzate per verificare se l'espressione si trova all'inizio o alla fine del testo. Volendo utilizzare le ancore su già righe di testo, si può attivare l'opzione `m`. Ad esempio, l'espressione regolare `/at(.)?$/gm` corrisponde a: una lettera minuscola `a`, seguita da una lettera minuscola `t` e, opzionalmente, qualsiasi carattere eccetto invio e nuova riga. Grazie all'opzione `m`, la corrispondenza viene estesa a ciascuna riga del testo.
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.

+## 6. Corrispondenza vorace vs pigra
+Regex ha un funzionamento predefinito vorace, ,significa che la corrispondenza è più estesa possibile. Si può utilizzare `?` per determinare una corrispondenza più pigra, così la corrispondenza è più breve possibile.

+
+> Ekspresi reguler adalah sekelompok karakter atau simbol yang digunakan untuk menemukan pola tertentu dalam sebuah teks.
+
+Ekspresi reguler adalah pola yang dicocokkan dengan string subjek dari
+kiri ke kanan. Ekspresi reguler digunakan untuk mengganti teks dalam string,
+memvalidasi formulir, mengekstrak substring dari string berdasarkan kecocokan pola,
+dan masih banyak lagi. Istilah "ekspresi reguler" adalah suap, jadi kamu biasanya akan
+temukan istilah yang disingkat "regex" atau "regexp". 
+
+Bayangkan Anda sedang menulis aplikasi dan Anda ingin menetapkan aturan kapan a
+pengguna memilih nama pengguna mereka. Kami ingin mengizinkan nama pengguna berisi huruf,
+angka, garis bawah, dan tanda hubung. Kami juga ingin membatasi jumlah karakter
+di username agar tidak terlihat jelek. Kita dapat menggunakan ekspresi reguler berikut untuk
+memvalidasi nama pengguna:
+
+


+

+  Regular expression
+

+
+Ekspresi reguler di atas dapat menerima string `john_doe`, `jo-hn_doe` dan
+`john12_as`. Itu tidak cocok dengan `Jo` karena string itu berisi huruf besar
+surat dan juga terlalu pendek.

+## 1. Pencocokan Dasar
+
+Ekspresi reguler hanyalah pola karakter yang kita gunakan untuk melakukan
+pencarian dalam sebuah teks. Misalnya, ekspresi reguler `the` berarti: huruf
+`t`, diikuti huruf `h`, diikuti huruf `e`.
+
+
+"the" => The fat cat sat on the mat.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/dmRygT/1)
+
+Ekspresi reguler `123` cocok dengan string `123`. Ekspresi reguler adalah
+dicocokkan dengan string input dengan membandingkan setiap karakter di reguler
+ekspresi ke setiap karakter dalam string input, satu demi satu. Reguler
+ekspresi biasanya peka huruf besar/kecil sehingga ekspresi reguler `The` akan
+tidak cocok dengan string `the`.
+
+
+"The" => The fat cat sat on the mat.

+
+## 2. Karakter Meta
+
+Karakter meta adalah blok bangunan ekspresi reguler. Meta
+karakter tidak berdiri sendiri tetapi sebaliknya ditafsirkan dalam beberapa
+cara spesial. Beberapa karakter meta memiliki arti khusus dan tertulis di dalamnya
+tanda kurung siku. Karakter metanya adalah sebagai berikut:
+
+|Meta karakter|Deskripsi|
+|:----:|----|
+|.|Titik cocok dengan karakter tunggal apa pun kecuali jeda baris.|
+|[ ]|Kelas karakter. Mencocokkan karakter apa pun yang ada di antara tanda kurung siku.|
+|[^ ]|Kelas karakter yang dinegasikan. Cocok dengan karakter apa pun yang tidak ada di antara tanda kurung siku|
+|*|Mencocokkan dengan 0 atau lebih pengulangan dari simbol sebelumnya.|
+|+|Mencocokkan 1 atau lebih pengulangan dari simbol sebelumnya.|
+|?|Jadikan simbol sebelumnya opsional.|
+|{n,m}|Kurung Kurawal. Mencocokkan setidaknya "n" tetapi tidak lebih dari "m" pengulangan simbol sebelumnya.|
+|(xyz)|Kelompok karakter. Mencocokkan karakter xyz dalam urutan yang tepat.|
+|||Alternasi. Mencocokkan dengan karakter sebelum atau karakter setelah simbol.|
+|\|Meloloskan dari karakter berikutnya. Ini memungkinkan Anda untuk mencocokkan karakter yang dipesan [ ] ( ) { } . * + ? ^ $ \ ||
+|^|Mencocokkan dengan awal input.|
+|$|Mencocokkan dengan akhir input.|
+
+## 2.1 Perhentian Penuh
+
+Tanda titik `.` adalah contoh paling sederhana dari karakter meta. Karakter meta `.`
+cocok dengan karakter tunggal apa pun. Itu tidak akan cocok dengan karakter kembali atau baris baru.
+Misalnya, ekspresi reguler `.ar` berarti: karakter apa pun, diikuti oleh
+huruf `a`, diikuti dengan huruf `r`.
+
+
+".ar" => The car parked in the garage.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/xc9GkU/1)
+
+## 2.2 Set Karakter
+
+Kumpulan karakter juga disebut kelas karakter. Tanda kurung siku digunakan untuk
+menentukan set karakter. Gunakan tanda hubung di dalam set karakter untuk menentukan
+jangkauan karakter. Urutan rentang karakter di dalam tanda kurung siku
+tidak masalah. Misalnya, ekspresi reguler `[Tt]he` berarti: huruf besar
+`T` atau huruf kecil `t`, diikuti huruf `h`, diikuti huruf `e`.
+
+
+"[Tt]he" => The car parked in the garage.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/2ITLQ4/1)
+
+Sebuah periode di dalam set karakter, bagaimanapun, berarti periode literal. yang biasa
+ekspresi `ar[.]` berarti: karakter huruf kecil `a`, diikuti dengan huruf `r`,
+diikuti dengan karakter titik `.`.
+
+
+"ar[.]" => A garage is a good place to park a car.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/wL3xtE/1)
+
+### 2.2.1 Set Karakter yang Dinegasikan
+
+Secara umum, simbol tanda sisipan mewakili awal string, tetapi ketika itu
+diketik setelah kurung siku pembuka itu meniadakan set karakter. Untuk
+contoh, ekspresi reguler `[^c]ar` berarti: karakter apa pun kecuali `c`,
+diikuti dengan karakter `a`, diikuti dengan huruf `r`.
+
+
+"[^c]ar" => The car parked in the garage.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/nNNlq3/1)
+
+## 2.3 Pengulangan
+
+Karakter meta `+`, `*` atau `?` digunakan untuk menentukan berapa kali a
+subpola dapat terjadi. Karakter meta ini bertindak secara berbeda di berbagai
+situasi.
+
+### 2.3.1 Tanda Bintang
+
+Simbol `*` cocok dengan nol atau lebih pengulangan dari pencocokan sebelumnya. Itu
+ekspresi reguler `a*` berarti: nol atau lebih pengulangan dari huruf kecil sebelumnya
+karakter `a`. Tetapi jika itu muncul setelah set karakter atau kelas maka ia menemukan
+pengulangan seluruh set karakter. Misalnya, ekspresi reguler
+`[a-z]*` artinya: sejumlah huruf kecil dalam satu baris.
+
+
+"[a-z]*" => The car parked in the garage #21.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/7m8me5/1)
+
+Simbol `*` dapat digunakan dengan karakter meta `.` untuk mencocokkan string apa pun dari
+karakter `.*`. Simbol `*` dapat digunakan dengan karakter spasi putih `\s`
+untuk mencocokkan string karakter spasi. Misalnya, ungkapan
+`\s*cat\s*` artinya: nol spasi atau lebih, diikuti dengan huruf kecil `c`,
+diikuti dengan huruf kecil `a`, diikuti dengan huruf kecil `t`,
+diikuti oleh nol atau lebih spasi.
+
+
+"\s*cat\s*" => The fat cat sat on the concatenation.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/gGrwuz/1)
+
+### 2.3.2 Tanda Tambah
+
+Simbol `+` cocok dengan satu atau lebih pengulangan karakter sebelumnya. Untuk
+contoh, ekspresi reguler `c.+t` berarti: huruf kecil `c`, diikuti oleh
+setidaknya satu karakter, diikuti dengan huruf kecil `t`. Itu perlu
+mengklarifikasi bahwa `t` adalah `t` terakhir dalam kalimat.
+
+
+"c.+t" => The fat cat sat on the mat.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/Dzf9Aa/1)
+
+### 2.3.3 Tanda Tanya
+
+Dalam ekspresi reguler, karakter meta `?` membuat karakter sebelumnya
+opsional. Simbol ini cocok dengan nol atau satu contoh karakter sebelumnya.
+Misalnya, ekspresi reguler `[T]?he` artinya: Huruf besar opsional
+`T`, diikuti dengan huruf kecil `h`, diikuti dengan huruf kecil `e`.
+
+
+"[T]he" => The car is parked in the garage.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/cIg9zm/1)
+
+
+"[T]?he" => The car is parked in the garage.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/kPpO2x/1)
+
+## 2.4 Braces
+
+Dalam ekspresi reguler, kurung kurawal (juga disebut quantifier) ​​digunakan untuk
+tentukan berapa kali karakter atau sekelompok karakter dapat
+ulang. Misalnya, ekspresi reguler `[0-9]{2,3}` berarti: Setidaknya cocok
+2 digit, tetapi tidak lebih dari 3, mulai dari 0 hingga 9.
+
+
+"[0-9]{2,3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/juM86s/1)
+
+Kita bisa meninggalkan nomor kedua. Misalnya, ekspresi reguler
+`[0-9]{2,}` berarti: Mencocokkan 2 digit atau lebih. Jika kita juga menghapus koma,
+ekspresi reguler `[0-9]{3}` berarti: Sama persis dengan 3 digit.
+
+
+"[0-9]{2,}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/Gdy4w5/1)
+
+
+"[0-9]{3}" => The number was 9.9997 but we rounded it off to 10.0.
+

+
+[Test the regular expression](https://regex101.com/r/Sivu30/1)
+
+## 2.5 Menangkap Grup
+
+Grup penangkap adalah grup subpola yang ditulis di dalam tanda kurung
+`(...)`. Seperti yang dibahas sebelumnya, dalam ekspresi reguler, jika kita menempatkan quantifier
+setelah karakter maka akan mengulangi karakter sebelumnya. Tetapi jika kita menempatkan quantifier
+setelah grup penangkap kemudian mengulangi seluruh grup penangkap. Sebagai contoh,
+ekspresi reguler `(ab)*` cocok dengan nol atau lebih pengulangan karakter
+"ab". Kita juga dapat menggunakan karakter meta `|` bergantian di dalam grup penangkap.
+Misalnya, ekspresi reguler `(c|g|p)ar` berarti: huruf kecil `c`,
+`g` atau `p`, diikuti oleh `a`, diikuti oleh `r`.
+
+
+"(c|g|p)ar" => The car is parked in the garage.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/tUxrBG/1)
+
+Perhatikan bahwa menangkap grup tidak hanya cocok, tetapi juga menangkap, karakter untuk digunakan dalam
+bahasa induk. Bahasa induk bisa berupa Python atau JavaScript atau hampir semua
+bahasa yang mengimplementasikan ekspresi reguler dalam definisi fungsi.
+
+### 2.5.1 Grup yang Tidak Menangkap
+
+Grup yang tidak menangkap adalah grup yang cocok dengan karakter tetapi
+tidak menangkap kelompok. Grup yang tidak menangkap dilambangkan dengan `?` diikuti oleh `:`
+dalam tanda kurung `(...)`. Misalnya, ekspresi reguler `(?:c|g|p)ar` mirip dengan
+`(c|g|p)ar` karena cocok dengan karakter yang sama tetapi tidak akan membuat grup tangkapan.
+
+
+"(?:c|g|p)ar" => The car is parked in the garage.
+

+
+[Test the regular expression](https://regex101.com/r/Rm7Me8/1)
+
+Grup yang tidak menangkap dapat berguna saat digunakan dalam fungsi temukan-dan-ganti atau
+ketika dicampur dengan grup penangkap untuk menjaga gambaran umum saat memproduksi jenis keluaran lainnya.
+Lihat juga [4. Melihat-lihat](#4-lookaround).
+
+## 2.6 Alternasi
+
+Dalam ekspresi reguler, bilah vertikal `|` digunakan untuk mendefinisikan pergantian.
+Pergantian seperti pernyataan OR antara beberapa ekspresi. Sekarang, Anda mungkin
+berpikir bahwa set karakter dan pergantian bekerja dengan cara yang sama. Tapi yang besar
+perbedaan antara set karakter dan pergantian adalah bahwa set karakter bekerja di
+tingkat karakter tetapi pergantian bekerja pada tingkat ekspresi. Misalnya,
+ekspresi reguler `(T|t)he|car` berarti: baik (huruf besar `T` atau huruf kecil
+`t`, diikuti dengan huruf kecil `h`, diikuti dengan huruf kecil `e`) ATAU
+(huruf kecil `c`, diikuti dengan huruf kecil `a`, diikuti oleh
+huruf kecil `r`). Perhatikan bahwa saya menyertakan tanda kurung untuk kejelasan, untuk menunjukkan bahwa salah satu ekspresi
+dalam tanda kurung dapat dipenuhi dan itu akan cocok.
+
+
+"(T|t)he|car" => The car is parked in the garage.
+

+

+
+## 2.7 Karakter Spesial
+
+Garis miring terbalik `\` digunakan dalam ekspresi reguler untuk keluar dari karakter berikutnya. Ini
+memungkinkan kita untuk menyertakan karakter yang dicadangkan seperti `{ } [ ] / \ + * . $ ^ | ?` sebagai karakter yang cocok. Untuk menggunakan salah satu karakter khusus ini sebagai karakter yang cocok, awali dengan `\`.
+
+Misalnya, ekspresi reguler `.` digunakan untuk mencocokkan karakter apa pun kecuali a
+garis baru. Sekarang, untuk mencocokkan `.` dalam string input, ekspresi reguler
+`(f|c|m)at\.?` artinya: huruf kecil `f`, `c` atau `m`, diikuti dengan huruf kecil
+`a`, diikuti dengan huruf kecil `t`, diikuti dengan `.` . opsional
+karakter.
+
+
+"(f|c|m)at\.?" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/DOc5Nu/1)
+
+## 2.8 Anchor Text
+
+Dalam ekspresi reguler, kami menggunakan jangkar untuk memeriksa apakah simbol yang cocok adalah
+simbol awal atau simbol akhir dari string input. Jangkar terdiri dari dua jenis:
+Tipe pertama adalah tanda sisipan `^` yang memeriksa apakah karakter yang cocok adalah yang pertama
+karakter input dan tipe kedua adalah tanda dolar `$` yang memeriksa apakah cocok
+karakter adalah karakter terakhir dari string input.
+
+### 2.8.1 Tanda Sisipan
+
+Simbol tanda sisipan `^` digunakan untuk memeriksa apakah karakter yang cocok adalah karakter pertama
+dari string masukan. Jika kita menerapkan ekspresi reguler berikut `^a` (artinya 'a' harus
+karakter awal) ke string `abc`, itu akan cocok dengan `a`. Tapi jika kita melamar
+ekspresi reguler `^b` ke string di atas, itu tidak akan cocok dengan apa pun.
+Karena dalam string `abc`, "b" bukanlah karakter awal. Mari lihat
+di ekspresi reguler lain `^(T|t)he` yang artinya: huruf besar `T` atau
+huruf kecil `t` harus menjadi karakter pertama dalam string, diikuti oleh a
+huruf kecil `h`, diikuti dengan huruf kecil `e`.
+
+
+"(T|t)he" => The car is parked in the garage.

+
+### 2.8.2 Tanda Dolar
+
+Tanda dolar `$` digunakan untuk memeriksa apakah karakter yang cocok adalah karakter terakhir
+dalam tali. Misalnya, ekspresi reguler `(at\.)$` berarti: a
+huruf kecil `a`, diikuti dengan huruf kecil `t`, diikuti oleh `.`
+karakter dan matcher harus berada di akhir string.

+
+##  3. Set Karakter Singkatan
+
+Ada sejumlah singkatan yang mudah digunakan untuk set karakter yang umum digunakan/
+ekspresi reguler:
+
+|Singkatan|Deskripsi|
+|:----:|----|
+|.|Karakter apa pun kecuali baris baru|
+|\w|Mencocokkan karakter alfanumerik: `[a-zA-Z0-9_]`|
+|\W|Mencocokkan karakter non-alfanumerik: `[^\w]`|
+|\d|Mencocokkan digit: `[0-9]`|
+|\D|Mencocokkan non-digit: `[^\d]`|
+|\s|Mencocokkan karakter spasi putih: `[\t\n\f\r\p{Z}]`|
+|\S|Mencocokkan karakter non-spasi: `[^\s]`|
+
+## 4. Melihat-lihat
+
+Melihat ke belakang dan melihat ke depan (juga disebut melihat sekeliling) adalah jenis tertentu dari
+***grup non-penangkapan*** (digunakan untuk mencocokkan pola tetapi tanpa menyertakannya dalam pencocokan
+daftar). Lookarounds digunakan ketika sebuah pola harus
+didahului atau diikuti oleh pola lain. Misalnya, bayangkan kita ingin mendapatkan semua
+angka yang didahului oleh karakter `$` dari string
+`$4,44 dan $10,88`. Kami akan menggunakan ekspresi reguler berikut `(?<=\$)[0-9\.]*`
+yang artinya: dapatkan semua angka yang mengandung karakter `.` dan didahului
+oleh karakter `$`. Ini adalah lookaround yang biasa digunakan
+ekspresi:
+
+|Simbol|Deskripsi|
+|:----:|----|
+|?=|Pandangan ke Depan Positif|
+|?!|Melihat ke Depan Negatif|
+|?<=|Tampilan Positif di Belakang|
+|?
+"(T|t)he(?=\sfat)" => The fat cat sat on the mat.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/IDDARt/1)
+
+### 4.2 Pandangan ke Depan Negatif
+
+Pandangan negatif ke depan digunakan ketika kita perlu mendapatkan semua kecocokan dari string input
+yang tidak mengikuti pola tertentu. Sebuah lookahead negatif ditulis dengan cara yang sama seperti a
+pandangan positif ke depan. Satu-satunya perbedaan adalah, alih-alih tanda sama dengan `=`, kami
+gunakan tanda seru `!` untuk menunjukkan negasi yaitu `(?!...)`. Yuk simak berikut ini
+ekspresi reguler `(T|t)he(?!\sfat)` yang artinya: dapatkan semua kata `The` atau `the`
+dari string input yang tidak diikuti oleh karakter spasi dan kata `fat`.
+
+
+"(T|t)he(?!\sfat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/V32Npg/1)
+
+### 4.3 Pandangan Positif ke Belakang
+
+Positif melihat ke belakang digunakan untuk mendapatkan semua kecocokan yang didahului oleh a
+pola tertentu. Positif lookbehinds ditulis `(?<=...)`. Misalnya,
+ekspresi reguler `(?<=(T|t)he\s)(fat|mat)` artinya: dapatkan semua kata `fat` atau `mat`
+dari string input yang datang setelah kata `The` atau `the`.
+
+
+"(?<=(T|t)he\s)(fat|mat)" => The fat cat sat on the mat.
+

+
+[Test the regular expression](https://regex101.com/r/avH165/1)
+
+### 4.4 Pandangan negatif ke belakang
+
+Pandangan belakang negatif digunakan untuk mendapatkan semua kecocokan yang tidak didahului oleh a
+pola tertentu. Tampilan negatif di belakang ditulis `(?
+"(?<!(T|t)he\s)(cat)" => The cat sat on cat.

+
+## 5. Bendera
+
+Bendera juga disebut pengubah karena mereka memodifikasi output dari regular
+ekspresi. Bendera ini dapat digunakan dalam urutan atau kombinasi apa pun, dan merupakan
+bagian integral dari RegExp.
+
+|Bendera|Deskripsi|
+|:----:|----|
+|i|Tidak peka huruf besar/kecil: Pencocokan tidak peka huruf besar/kecil.|
+|g|Penelusuran Global: Cocokkan semua instance, bukan hanya yang pertama.|
+|m|Multiline: Karakter meta jangkar bekerja di setiap baris.|
+
+### 5.1 Tidak peka huruf besar/kecil
+
+Pengubah `i` digunakan untuk melakukan pencocokan case-insensitive. Misalnya,
+ekspresi reguler `/The/gi` berarti: huruf besar `T`, diikuti dengan huruf kecil
+`h`, diikuti oleh `e`. Dan di akhir ekspresi reguler
+flag `i` memberitahu mesin ekspresi reguler untuk mengabaikan kasus ini. Sebisa kamu
+lihat, kami juga menyediakan flag `g` karena kami ingin mencari pola di
+seluruh string masukan.
+
+
+"The" => The fat cat sat on the mat.
+

+
+[Uji ekspresi reguler](https://regex101.com/r/dpQyf9/1)

+
+[Uji ekspresi reguler](https://regex101.com/r/ahfiuh/1)
+
+### 5.2 Pencarian Global
+
+Pengubah `g` digunakan untuk melakukan kecocokan global (menemukan semua kecocokan daripada
+berhenti setelah pertandingan pertama). Misalnya, ekspresi reguler`/.(at)/g`
+berarti: karakter apa pun kecuali baris baru, diikuti dengan huruf kecil `a`,
+diikuti dengan huruf kecil `t`. Karena kami menyediakan flag `g` di akhir
+ekspresi reguler, sekarang akan menemukan semua kecocokan dalam string input, bukan hanya yang pertama (yang merupakan perilaku default).

+"/.(at)/" => The fat cat sat on the mat.

+
+### 5.3 Multiline
+
+Pengubah `m` digunakan untuk melakukan pencocokan multi-baris. Seperti yang telah kita bahas sebelumnya,
+jangkar `(^, $)` digunakan untuk memeriksa apakah suatu pola ada di awal input atau
+tamat. Tetapi jika kita ingin jangkar bekerja pada setiap baris, kita menggunakan
+bendera `m`. Misalnya, ekspresi reguler `/at(.)?$/gm` berarti: huruf kecil
+`a`, diikuti dengan huruf kecil `t` dan, opsional, apa pun kecuali
+baris baru. Dan karena flag `m`, mesin ekspresi reguler sekarang cocok dengan pola
+di akhir setiap baris dalam sebuah string.
+
+
+"/.at(.)?$/" => The fat
+                cat sat
+                on the mat.

+
+## 6. Greedy vs Lazy Matching
+Secara default, regex akan melakukan kecocokan greedy, yang berarti kecocokan akan berlangsung selama
+mungkin. Kita dapat menggunakan `?` untuk mencocokkan dengan cara yang lazy, yang berarti pencocokan harus sesingkat mungkin.
+
+
+"/(.*at)/" => The fat cat sat on the mat.
