We are currently using DeltaXML in our .Net application to analyse two versions of .xml files regarding their differences, but since DeltaXML is a java application/library, we're looking for a more homogeneous way to accomplish that task.
Does anyone know a .Net diff library similiar to DeltaXML?
I don't know DeltaXML, but you could try XML Diff from Microsoft, which is available in source - well at least parts of it.
I have used it successfully for doing "XML aware" diffs on test results.
However, it looks rather old/defunct now, so your milage may vary.
Not a library, but an application that computes deltas based on language (e.g., XML) structures. See SD Smart Differencer. There is an XML version even if it isn't obvious from the web site.
