@atamer looks ok. Please squash the two commits to a single one and also add some unit-tests for the parsing process.

@atamer are you planing any changes here?

I'm unable to see the exact fix in the code. There is a lot of styling changes in this change. Let's make sure that we have a targeted fix.

Are we saying that "data" within an object can break our xml parser? I would like the library to break when the envelope XML returned by the service is broken. However, it shouldn't break if the data has complete non-sense. Are we doing the right escaping?

@atamer plz remove the unecessary commits. If you dont I will create another PR of this. With only the small change left.
