Question

I have problems with the Xpath expression test=”$roles/roles/role=’HOBSCS1GB'” . Can anyone help in solving. Thanks

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> 

  <xsl:template match="/"> 

    <xsl:variable name="roles"> 
  <roles> 
    <role>HOBSCS1ROI</role> 
    <role>HOBSCS1GB</role>

    <xsl:if test="$roles/roles/role='HOBSCS1GB'">
      <xsl:value-of select="'YES'"/>
    </xsl:if> 

  </xsl:template>

Assuming you want to find if a the roles element has one or more role elements with text = ‘HOBSCS1GB’: (Works in Saxon)

<xsl:if test="$roles/roles[role='HOBSCS1GB']">
  <xsl:value-of select="'YES'"/>
</xsl:if>

Note that certain parsers like Microsoft may require you to tell the parser that $roles is a result tree fragment, by using node-set(), like so: (Works in msxsl)

<xsl:stylesheet ... xmlns:msxsl="urn:schemas-microsoft-com:xslt" ... />

<xsl:if test="msxsl:node-set($roles)/roles[role='HOBSCS1GB']">
  <xsl:value-of select="'YES'"/>
</xsl:if>

Or in xsltproc:

<xsl:stylesheet ... xmlns:exsl="http://exslt.org/common" ... />

<xsl:if test="exsl:node-set($roles)/roles[role='HOBSCS1GB']">
  <xsl:value-of select="'YES'"/>
</xsl:if>
