diffxml and patchxml: new XML-aware diff/patch utilities

Adrian Mouat has released diffxml and patchxml, new open-source Java-based utilities for diff'ing and patching XML files.

Mouat created diffxml and patchxml to meet the following list of criteria:

  • An output format that is good for patching changed files

  • A fast and accurate algorithm

  • The ability to handle large files

  • An open source license

  • Not strongly tied to a particular XML parser

  • Has an independent and fully specified output format

  • Support for including extra context information in diff output (necessary to produce good patches for documents other than those from which the delta was computed)

In part, Mouat seems to have created diffxml because none of that criteria is met completely by any of the other existing "XML diff" utilities:
