have you tried [stackoverflow](http://stackoverflow.com), its not specialist by any means but covers all aspects of programming. In terms of an xml editor, i prefer [Liquid XML Studio](http://www.liquid-technologies.com/xml-editor.aspx) as i am windows based.

Firstly you should validate your xml file before you try and parse, you should be able to find a suitable xml parserby googling it, i work with [URL="http://www.liquid-technologies.com/xml-editor.aspx"]Liquid XML Editor[/URL] but feel free to pick whichever you want.
