Re: Grouping duplicate elements under one element

Hi,
I have the following XML fragment, and I want to group duplicate course
elements under one course element. WHat is the best way of doing it? Cihan

It's again the old trusty spell named Muenchean grouping, just
invoked three times in the last few hours.

 <xsl:key name="course" match="course" use="LOCAL_CRSE_CD"/>
 <xsl:template match="courses">
  <courses>
   <xsl:for-each select="course[generate-id()=
      generate-id(key('course',LOCAL_CRSE_CD)[1])]">
     <course>
       <xsl:copy-of select="LOCAL_CRSE_CD"/>
       <xsl:for-each select="key('course',LOCAL_CRSE_CD)">
         <xsl:copy-of select="*[not(self::LOCAL_CRSE_CD)]"/>
       </xsl:for-each>
     </course>
    </xsl:for-each>
  </courses>
 </xsl:template>
