[xsl] Value Mapping

["oknam park" <ponda7777@xxxxxxxxxxx>]

Hi All,

I need another help.

I need value mapping when a value in the subelement is matched with some 
value string.

xml instance:
<audience>
<toolfor scheme="GEM">
  Students
</toolfor>

My xslt:
<xsl:template match="audience">
<xsl:for-each select="audience/beneficiary[@scheme='GEM']">
   <xsl:choose>
      <xsl:when test=". = 'Students'"><gemq:beneficiary 
rdf:resource="http://purl.oclc.org/gem/instance/GEM-BEN/#Students"/></xsl:when>
   </xsl:choose>
</xsl:for-each>  </xsl:template>

Could you give me some help?

I would be appreciated.

Thanks a lot,

Best regards,
Oknam Park
