EXPath

This module is still a work in progress. An implementation exists for Saxon, but the specification has not been written yet, and there is almost no documentation. An introduction to EXPath, presented at Balisage in August 2009 contains examples, see the proceedings and the materials page. Any help, comment or suggestion greatly appreciated on the mailing list.

The current implementation for Saxon is provided as a XAR package: expath-zip-saxon-0.1.xar. You can use this package with the Packaging System, or just open it as a ZIP file, get the JAR file within it, and set your Saxon processor up (especially the classpath). Here is an complete example (provided you correctly installed the package in your repository, you can just save it in a file and execute it with saxon -xsl:zip-list.xsl -it=main file=.../some/file.zip):
