New page

Schematron validation can be performed on XML files which need testing. For this one needs a XSL processor. We recommend [https://sourceforge.net/projects/saxon/files/Saxon-HE/ Saxon-HE], a powerful open source application.

Usage:
When the following folder structure is used (with the downloaded and extracted Saxon HE in the 'saxon' folder):
- saxon
- bin
- test
- testfile.xml
- schematron
- checks.sch
- checks.xsl

schematron validation can be performed with the following command (example under DOS):
$ saxon\bin\Transform
-t
-s:test\testfile.xml
-xsl:schematron\checks.xsl
-o:report.xml

The used schematron must be the SVRL version of Schematron. Usually this is delivered for ART projects, as a *.xsl or *_svrl.xsl version. When there is no SVRL version, this can be made. Instructions and tools can be found at [https://github.com/Schematron/schematron Github Schematron]. (SVRL is a 'xxx.sch' Schematron transformed to a 'xxx.xsl' version of it. The latter transforms a XML file to an error report.)

This generates a report.xml file. A basic HTML view can be made with the following stylesheet:
'''svrl2html.xsl:'''
<syntaxhighlight lang="xml">
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:svrl="http://purl.oclc.org/dsdl/svrl">
<xsl:output method="html" indent="yes"/>

<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>SVRL report</title>
<style>
body {margin:8px;}
a[href] {color:blue;}
</style>
</head>
<body>
<h1>SVRL report</h1>
<div>Errors: <xsl:value-of select="count(.//svrl:failed-assert)"/></div>
<xsl:for-each select=".//svrl:failed-assert">
<ul>
<li><b>Text: <xsl:value-of select="svrl:text"/></b></li>
<li>Test: <xsl:value-of select="@test"/></li>
<li>See: <xsl:value-of select="@see"/></li>
<li>Location: <xsl:value-of select="@location"/></li>
</ul>
</xsl:for-each>
</body>
</html>
</xsl:template>

<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
</syntaxhighlight>

This transform again can be done with Saxon:
$ saxon\bin\Transform
-t
-s:report.xml
-xsl:svrl2html.xsl
-o:report.html
