Re: [xsl] Recursive substitution

[Agnisys <agnisys@xxxxxxxxx>]

Unfortunately my problem is that I did want to use a "copy-of" so that the nodes being referred to
by the <ref> tag are actually "stitched" into the tree.
I tried to use the following but it doesn't seem to do the job. Note the use of "copy-of" and
"ancestor::define".

Any pointers?
Thanks,
Anupam.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="2.0">
  
    <xsl:key name="r" match="define" use="@name"/>
    
    <xsl:template match="x">
        <xsl:apply-templates select="block"/>
    </xsl:template>
    
    <xsl:template match="reg">
      <xsl:if test="not(ancestor::define)">
        Register: <xsl:value-of select="@name"/><br/>
      </xsl:if>
    </xsl:template>
   
    
    <xsl:template match="ref[@name]"> 
        <xsl:variable name="x">
            <xsl:copy-of select="key('r',@name)"/>
        </xsl:variable>
        <xsl:apply-templates select="$x"/>
    </xsl:template>
   
</xsl:stylesheet>
