So are you trying to do the XML differencing on an Apache server like I am?
Well, I've been running in circles looking at this stuff so I started a list of all the XML differencing apps that I've come across. I tried to list each app with a URL, a license type, and positives/negatives about it. '?' means I'm not quite sure. If anyone has any additions or corrections, I'd be glad to hear it!

Christopher,
It was weird synchronicity seeing this topic come up. I had just started looking at XML diff software and found the usual
suspects: the IBM one (xmldiff), the SourceForge one (diffxml),
a Python module (xmldiff) and the Microsoft one (xmldiffpatch).
My interest is in exposing changes in web services by providing a diff of the WSDL.
I haven't gotten very far down the road. what I've learned:
- naive diff is no good because hierarchical data can take many equivalent forms - There is no standard diff format, so those who implement it also usually write their own patch. - There are visual diffs, but I haven't gotten any of them to work. - The diff applications differ in complexity; the most complex will compare node names to attributes, etc., in trying to make a match. And to make this work, the app generally builds a DOM ... which limits the size of the documents it can compare.
I don't know if that's helpful or not ...
Here are links to the xml diffs I found:
