Java XML diff toolkit

21:17, 13 Dec 2001 UTC | Bijan Parsia

Joining the swelling ranks of tools for generating deltas between XML documents, VMTools is a new open source Java toolkit.

Features include:

cost optimizer finds differences in document oriented XML as quickly as in data-oriented XML
sample programs show "diff" and "patch" style functionality in a few dozen lines each
web-based DifferenceGenerator and PatchApplicator available online
builds on JDOM
XPath subset implementation

VMTools is available for download under an Apache-like open source license.

The "VM Tools" Java Diff is almost totally useless. Sorry to say that. I use one of their example13.xml, and made one text change and added only one simple element. The diff I got from any other text diff tools was exact two lines. However, the VM Tools gave me incredible amount of bogus diffs.

I've not read the source code, and not plan to read either. However, I'm pretty sure it did not use the tree (graph) structure to do the XML diff. Otherwise, the result I got would be impossible.

Thanks! Roseanne
