Re: [xsl] backtracking to find all parents till root[again]

Rahil,

It's still not a watertight problem statement, but the following will 
produce what you want, and I imagine you can press it into better service if 
need be.

<?xml version="1.0" encoding="iso8859-1"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
   <xsl:output method="text" indent="yes"/>

   <xsl:template match="/">
       <xsl:variable name="find" select="'NextTime'"/>

       <xsl:apply-templates 
select="Top/SubConcepts/SubConcept/Value[contains(., $find)]"/>
       <xsl:text>Parent: SubConcepts</xsl:text>
   </xsl:template>

   <xsl:template match="Value">
       <xsl:text>Match Found: </xsl:text><xsl:value-of select="."/>
       <xsl:text>&#xa;</xsl:text>

       <xsl:apply-templates select="parent::SubConcept[1]"/>
   </xsl:template>

   <xsl:template match="SubConcept">
       <xsl:text>Parent: </xsl:text><xsl:value-of select="@name"/>
       <xsl:text>&#xa;</xsl:text>

       <xsl:apply-templates 
select="preceding-sibling::SubConcept[contains(Value, 
current()/@name)][1]"/>
   </xsl:template>

</xsl:stylesheet>
