Handle well-indented XML including comments#795
Merged
Conversation
The root cause for #782 was misuse of xmerl_scan:string/2, which doesn't emit spaces, comments between actual xml elements. It leaves them as #xmlText{} and #xmlComment{} - This commit changes to ignore them at walking around parsed dom tree. This diffset also includes a small refactoring that wraps all xmerl_scan:string/2 to one riak_cs_xml funcsion to control its usage. This also adds regression test as simple eunit test case. Conflicts: src/riak_cs_acl_utils.erl src/riak_cs_s3_response.erl

Really nitpicky, but why assign this to Xml, instead of just returning the string?

Without binding Xml the indentation by erlang-mode.el becomes like this:
"<!-- comments here --> <AccessControlPolicy> <!-- comments here -->"
" <Owner> <!-- blah blah blah -->"
" <ID>eb874c6afce06925157eda682f1b3c6eb0f3b983bbee3673ae62f41cce21f6b1</ID>"
" <!-- c --> <DisplayName>admin</DisplayName> <!--"
" \n --> </Owner>"Also it's easy to put some ~p to do some formatting like io_lib:format(Xml, [ Blah, Blah, ... ]) for future improvement. Yes, I was trying that.
