Re: Build up xpath dynamically in xslt

Hi Joe,

There is an easier way.

Use <xsl:key> to build an index of all the image nodes based on 
uniquereferenceid.  Then use the key() function to return the image 
nodes that match the uniquereferenceid of the property node.

Something like this:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="images" match="/web_transfer/images"
   use="uniquereferenceid"/>
<xsl:template match="/">
   <xsl:for-each select="web_transfer/property">
     <image1>
       <xsl:value-of
   select="key('images',uniquereferenceid)[position()=1]/imageurl"/>
     </image1>
   </xsl:for-each>
</xsl:template>
</xsl:stylesheet>
