Re: [oXygen-user] RelaxNG and Schematron

11 Mar 2009

      Hello Christian,

You did not send layout_definitions.rng so I cannot test the whole 
schema on an XML document. Your schema has at least two problems:

1. You have to use the ISO Schematron namespace in a RELAX NG schema, 
not the Schematron 1.5 one, that is:

xmlns:sch="http://purl.oclc.org/dsdl/schematron"

2. You have to specify the target namespace of the schema in the XPath 
expressions:

   <sch:ns prefix="layout" uri="http://www.docscape.de/layoutV4.2"/>

   <sch:pattern>
     <sch:rule context="//layout:Regel[@datensatz and @name]">
         <sch:assert
           test="count(//layout:Regel[@name=current()/@name and
           @datensatz=current()/@datensatz]) le 1"

Regards,
Sorin

Hi there!
Due to some restrictions of XML Schema we are currently changing to
RelaxNG. I now tried to take some Schematron rules of the old schema and
put it in the new RelaxNG Schema to test if Schematron will work.
This is my "root" File which includes other RelaxNG Schemas:
<?xml version="1.0" encoding="UTF-8"?>
<grammar xmlns="http://relaxng.org/ns/structure/1.0"
  xmlns:a="http://relaxng.org/ns/compatibility/annotations/1.0"
  xmlns:sch="http://www.ascc.net/xml/schematron"
  datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes"
  ns="http://www.docscape.de/layoutV4.2">
<include href="layout_definitions.rng"/>
<sch:pattern>
    <sch:rule context="//Regel[@datensatz and @name]">
      <sch:assert test="count(//Regel[@name=current()/@name and
@datensatz=current()/@datensatz]) le 1">Die Regel »<sch:value-of
select="@name"/>« zu dem Datensatz »<sch:value-of select="@datensatz"/>«
ist mehrfach vorhanden.</sch:assert>
    </sch:rule>
    <sch:rule context="//Regel[@datensatz and not(@name)]">
      <sch:assert test="count(//Regel[@datensatz=current()/@datensatz
and not(@name)]) le 1">Die Regel  zum Datensatz »<sch:value-of
select="@datensatz"/>« ist mehrfach vorhanden.</sch:assert>
    </sch:rule>
    <sch:rule context="//Regel[@name and not(@datensatz)]">
      <sch:assert test="count(//Regel[@name=current()/@name and
not(@datensatz)]) le 1">Die Regel »<sch:value-of select="@name"/>« ist
mehrfach vorhanden.</sch:assert>
    </sch:rule>
    <sch:rule context="//Zuweisung">
        <sch:assert test="(//DefVariable[@name=current()/@name]) or
exists(Name)">Variable »<sch:value-of select="@name"/>« nicht
definiert.</sch:assert>
    </sch:rule>
  </sch:pattern>
  <start>
    <choice>
      <element name="Layout">
        <optional>
          <attribute name="version">
            <text/>
          </attribute>
        </optional>
        <optional><attribute name="datensatz"><text/></attribute></optional>
        <zeroOrMore>
          <interleave>
            <optional><ref name="g_Deklarationen"/></optional>
            <optional><ref name="g_Documentation"/></optional>
            <optional><ref name="x_Layoutinclude"/></optional>
          </interleave>
        </zeroOrMore>
      </element>
      <ref name="x_Layoutinclude"/>
    </choice>
  </start>
</grammar>
The're is just no effect to the validation. The rest of the Schema works
fine but the schematron rules have no effect. They seme to be ignored.
Any suggestions?
Thanks, Christian
