This repository contains an XML Calabash 1.0 extension step that can compare XML documents using DeltaXML.
This step should work with any recent XML Calabash release.
For standalone installation, get the most recent release from the project
releases page.
The release distributed there includes
relevant dependencies. Unpack it somewhere on your system and add the
included, top-level jar file to your class path.
If you're using Maven, you can also get it from there. Note, however, that
the Maven distribution includes a POM file that identifies other dependencies
that must also be downloaded. You'll need them too, which happens naturally
if you're including the Maven dependency in some other Maven project.
If you just grab the jar from Maven and don't get the other dependencies,
you're likely to find that the step doesn't work because of some missing
dependencies.
