How to validate an XML document against a Schematron file

These are all options:

• Use an xslt processor with a schematron engine (see Schematron website)
• Make an NVDL script and use onvdl.
• Use Probatron. Since the commandline command itself is a bit complicated, and it is often useful to see just the textual error messages rather than the entire

SVRL output, Syd has written a little front-end to it. If you speak bash, feel free to play with it as if it were copyleft Syd Bauman, available under the LGPL.

• The amazing Ken Holman has a text-only implementation based on the reference implementation.
• The <oXygen/> XML Editor has built-in support for validating against ISO Schematron.
• Syd has written a front-end to the reference implementation of Schematron, but he hasn't used it much since he started using Probatron. It depends on xmlstarlet being installed as `xml` and Saxon as `saxon`. If you speak bash, feel free to play with it as if it were copyleft Syd Bauman, available under the LGPL.
