Finally found a good tool to do XML Diff

I need to find a way to do XML diff, and came across three solutions:

- Free tool from IBM - XMLDiff
- Altova XMLSpy 2007 Enterprise Edition - 30 days trial version
- Stylus Studio 2007 XML Enterprise Release 2 - 30 days trial version

I couldn't get the IBM Tool working, and I couldn't quicktime find a way to do diff in XMLSpy 2007. Stylus Studio 2007 XML on the other hand is so simply and easy to use. So I settled with this one.
