Question

Unable to succeed in passing parameters in xsl (1.0) for . It seems that one cannot dynamically modify the content of the ‘select’. Below is an attempt that does not throw an error but fails to recognise the $entity parameter:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output cdata-section-elements="" encoding="UTF-8" indent="yes" method="xml" omit-xml-declaration="yes"/>   
    <xsl:param name="entity">CreditController[]</xsl:param>
        <xsl:template match="/">
            <xsl:element name="variable">
                  <xsl:attribute name="type">NameValuePair[]</xsl:attribute>
                      <xsl:apply-templates select="variable/*[@type='$entity']/item"/>                      
            </xsl:element>
    </xsl:template>

    <xsl:template match="item">                 
            <xsl:element name="item">
            <xsl:attribute name="type">NameValuePair</xsl:attribute>
            <xsl:element name="value">
                <xsl:attribute name="type">String</xsl:attribute>
                <xsl:value-of select="Code"/>
            </xsl:element>
            <xsl:element name="name">
                <xsl:attribute name="type">String</xsl:attribute>
                <xsl:value-of select="Code"/>-<xsl:value-of select="Value"/>
            </xsl:element>
            </xsl:element>
    </xsl:template>

</xsl:stylesheet>

Thanks in advance. Other posts seemed to recommend using and also setting ‘Mode’ attribute of the element. I did not win with either of these.

Replacing the entity variable with the string literal ‘CreditController[]’ works as expected.

Answer 1

In your XPath you surround your $entity with quotes, making it the string literal $entity and not a variable to be expanded.

Remove the quotes:

<xsl:apply-templates select="variable/*[@type=$entity]/item"/>
