IBM has a tool called XMLTreeDiff which does the following

"XMLTreeDiff compares two XML documents by examining their document
structures (their DOM representations), not by particular file
representations. It reports the differences in XML format as a sequence of
basic tree operations like replace node, remove node, and add node. In
addition, XMLTreeDiff provides a patch tool, which applies the update to a
source document to obtain an updated version of the source."
This is a java tool.
Hope that helps.
