I am attempting to add a custom function to my schematron rule stylesheet to aid in looking up values in code tables. I continue to receive an error message: "unrecognized element xsl:function from namespace http://www.w3.org/1999/Transform''

At the top of the file, I have the following declarations:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?> 

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

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

    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 

    xmlns:fn="http://www.w3.org/2005/xpath-functions"

    xmlns:local-fn="functions:1.0"

    xmlns:regexp="http://exslt.org/regular-expressions"

    queryBinding="xslt2"> 



    <sch:ns uri="functions:1.0" prefix="local-fn" />

and the function declaration as:

Code: Select all

<!-- *********************************** Functions ***********************  --> 

<!-- special variables for lookup table --> 

<xsl:key name="Code-Lookup" match="CodeTable" use="Code"/> 

<xsl:variable name="codeTables" select="document('LookupCodes.xml')/CodeTable"/> 

<!-- function to return an expression to be evaluated in the rule containing the codes from the given code table --> 

<xsl:function name="local-fn:BuildLookupExpression" as="xs:string"> 

    <xsl:param name="TableName" as="xs:string"/> 

    <xsl:text>(</xsl:text> 

    <xsl:for-each select="key('Code-Lookup', $TableName)/Code"> 

        <xsl:value-of select="."/> 

        <xsl:if test="position() != last()"> 

            <xsl:text>)|(</xsl:text> 

         </xsl:if> 

         <xsl:if test="position() = last()"> 

             <xsl:text>)</xsl:text> 

          </xsl:if> 

      </xsl:for-each> 

  </xsl:function>

in the body, I use the rule:

Code: Select all

<sch:pattern id="SEXValue"> 

       <sch:title>Person Sex</sch:title> 

       <sch:p class="description">

           This field is used to report the gender of the subject.

           See SEX Table: [F, G, M, N, X, Y, Z]

       </sch:p> 



       <let name="SEXExpression" value="local-fn:BuildLookupExpression('SEX')"/> 

       <sch:rule context="nc:PersonSexCode"> 

            <let name="SEXString" value="string(.)"/> 

            <sch:assert test="matches($SEXString, $SEXExpression)"> 

                <sch:value-of select="name(.)" /> must be in the set of: [F, G, M, N, X, Y, Z] 

            </sch:assert> 

         </sch:rule> 

      </sch:pattern>

What am I missing?

Hi,

Thank you for contacting us.

You should activate the option 'Allow foreign elements (allow-foreign)' from the 'XML / XML Parser / Schematron' option page. This option is used to pass non-Schematron elements to the generated stylesheet.
