A commercial product that probably does everything you want in the area of XML differencing is DeltaXML.

XMLUnit has exactly this functionality:

XMLTestCase.compareXML() has both DOM and SAX versions. Use DetailedDiff to get a list of all differences between the two XMLs. Convert this diff object to your own representation if needed.

XMLUnit is nice because it can treat similar XML documents (such as whitespace, sibling order, namespace prefixes) as the same if you want.
