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.
