Re: Recursive substitution

Peter,

this works for your example:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl"                
                xmlns="http://www.w3.org/TR/REC-html40"> 

<xsl:template match="/">
    <xsl:element name='PARAM'>
         <xsl:attribute name='name'>tree</xsl:attribute>
         <xsl:attribute
name='value'><xsl:apply-templates/></xsl:attribute>
   </xsl:element>   
</xsl:template>

<xsl:template match="CGROUP">
   <xsl:apply-templates/>
</xsl:template>

<xsl:template match="CGROUP" mode="$">
      $<xsl:apply-templates select=".." mode="$"/>
</xsl:template>

<xsl:template match="CITEM">
   <xsl:apply-templates select=".." mode="$"/>
   <xsl:apply-templates/>|
</xsl:template>

</xsl:stylesheet>
