New method for XML parsing error checking

[Alexander Obuhovich]

Another new method (previous was about curl response error checking) for checking of xml document parsing ended with error.

Task: http://tracker.in-portal.org/view.php?id=1001

Ready for testing.

Hi Alex,

What's a good test scenario here? Just test trying to parse valid and invalid XMLs, or something else should be checked?

That's not just a bad xml that is checked by this method.

There could be the case when:
1. error source could not be detected during xml parsing and "false" (boolean) is returned instead of root node object of xml document;
2. error source could be detected and then xml node object with ERROR word as it's name is returned.

Then you need to test:
- very malformed (or maybe empty string as input) xml
- little bit malformed xml
- good xml.
