[oXygen-user] Syntax problem with xslt 'contains' text()

[McGibbney, Lewis John]

Good Afternoon Everyone,

I have a large schema file [0].
I wish to grab a subset of the <xs:element>'s within the XSD and print them to a significantly smaller and more manageable/relevant output file.

In particular I wish to grab every occurrence of an <xs:element> where the substitutionGroup value is equal to "ifc:IfcBuildingElement"

I've been using the following xsl code and it is not working.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:xd="http://www.oxygenxml.com/ns/doc/xsl"
    xmlns:ifc="http://www.iai-tech.org/ifcXML/IFC2x3/FINAL"
    exclude-result-prefixes="xs xd"
    version="2.0">
    <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template name="main" match="/">
        <xsl:for-each select="xs:schema/xs:element">
            <xsl:if test="@substitutionGroup[contains(text(), ifc:IfcBuildingElement)]">
                    <xsl:value-of select="xs:schema/xs:element"/>
            </xsl:if>
        </xsl:for-each>
    </xsl:template>

</xsl:stylesheet>

It would be great if someone could point out to me either the incorrect syntax or the absence of the correct configuration.

Kind Regards

Lewis
