I found a shell script for Schematron that your supposed to be able to feed a Schematron schema, and an XML document, so as to apply the Schematron rules to the XML document. I found the script here:
https://code.google.com/p/schematron/wiki/RunningSchematronWithGNOMExsltproc
The various xsl files used by the script are downloaded from the Schematron distribution here:
http://www.schematron.com/implementation.html
I'll repeat the shell script here, for convenience.
#!/bin/bash
echo Step1 ...
xsltproc iso_dsdl_include.xsl $1 > step1.xsl
echo Step2 ...
xsltproc iso_abstract_expand.xsl step1.xsl > step2.xsl
echo Step3 ...
xsltproc iso_svrl_for_xslt1.xsl step2.xsl > step3.xsl
echo Validation ...
xsltproc step3.xsl $2 > result.svrl
I run the script like this:
run_schematron.sh docbook1.sch my_xml.xml
The shell script generates intermediate files, step1.xsl, step2.xsl, and step3.xsl. But I am already off the rails at step2.xsl, since it looks like this:
<?xml version="1.0"?>
@linkend on footnoteref must point to a footnote.
@linkend on synopfragmentref must point to a synopfragment.
That's not looking like an XSL stylesheet to me. Any ideas?
The problem is that you are using docbook.sch for DocBook 5.0, which is not an ISO Schematron schema (the namespace bound to the s: prefix is not http://purl.oclc.org/dsdl/schematron).
In docbook.sch for DocBook 5.0, simply change this:
xmlns:s="http://www.ascc.net/xml/schematron"
to this:
xmlns:s="http://purl.oclc.org/dsdl/schematron"
...and it will work.
In docbook.sch for DocBook 5.1 (which hasn't been offically released yet), the namespace has been changed.
