Re: Recursive substitution

I get
bash-2.01$ xt a.xml a.xsl
<PARAM name="tree" value="$depth 1| $depth 1| $$depth 2| $$depth 2| $depth 1| $depth 1| "/>

which I think is what you want?

from this


<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl"
                   default-space="strip">


 <xsl:template match="CGROUP" >
  <xsl:choose>
  <xsl:when test="ancestor(CGROUP)"><xsl:apply-templates/></xsl:when>
  <xsl:otherwise>
    <xsl:element name="PARAM">
    <xsl:attribute name='name'>tree</xsl:attribute>
    <xsl:attribute name='value'><xsl:apply-templates/></xsl:attribute>
    </xsl:element>
  </xsl:otherwise>
  </xsl:choose>
 </xsl:template>

 <xsl:template match="CITEM" >
  <xsl:apply-templates  mode="$" select="ancestor(CGROUP)" />
  <xsl:apply-templates/>
  <xsl:text>| </xsl:text>   
 </xsl:template>

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



</xsl:stylesheet>
