Re: [xsl] Traversing nodes and storing a matched value

[Mukul Gandhi <mukul_gandhi@xxxxxxxxx>]

Hi Mat,
  You may try something like this .. (Hope I got the
requirements right)

<?xml version="1.0"?> 
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
           xmlns:common="http://exslt.org/common";
           version="1.0">
 
 <xsl:output method="text" /> 
 
 <xsl:param name="siteID" select="'1'" />
 
 <xsl:template match="/"> 
   <xsl:variable name="rtf">
     <xsl:for-each select="//exsites">
       <xsl:choose>
         <xsl:when test=". = $siteID">
           <menu name="{parent::menu/@name}">
             <process x="yes" />
           </menu>
         </xsl:when>
         <xsl:otherwise>
           <menu name="{parent::menu/@name}">
	      <process x="no" />
           </menu>
         </xsl:otherwise>
       </xsl:choose>
     </xsl:for-each>
   </xsl:variable>
   
   <xsl:for-each
select="common:node-set($rtf)/menu/process[@x =
'yes']">
     <!-- do something -->
   </xsl:for-each>
 </xsl:template>

</xsl:stylesheet>

This example uses node-set function.. and tested with
Saxon 8.4.

Mukul
