If I were doing this in XSLT I'd use one of the documents as the source and 
bring the reference one in via the document() function.
Then I'd copy all nodes except the referenced ones. The difficulty would be 
to determine the matching nodes, can you show a small example of the two 
documents and the output you need?

The second question is you say you are using a data set, does this mean an 
ADO.NET dataset rather than XML files?
