I have a requirement like below. A client is sending his data(xml file) in a particular file format/structure and now he made few changes to the format (I guess he moved few field positions and added few fields/columns). What is the best way to compare the prior and revised file formats? I believe creating a DiffGram an option. However, I couldn't find enough info online on how to create the Diffgram. Can anyone out there pls help me?
