Word Document Problem

I have a document with a corrupt document.xml file. 

Error is "XML parsing error: Line: 2 Column: #######

I've tried to use an XML viewer to isolate the problem in the document.xml file, but I can't seem to get the file to open have re-zipping and renaming to a docx file.

Can anyone recover the file for me?

Thanks,

Richard
