I was thinking more along the lines of (please excuse any bum syntax
below - written in haste by a non-guru; the principle should be clear):

<xsl:template match="//div">
<xsl:variable name="seq"><xsl:number level="any" count="*"/></xsl:variable>
    <xsl:if test="$seq=$param_passed_in">
	<xsl:apply-templates select ="."/>

where param_passed_in was generated by:
<xsl:number level="any" count="*"/>
in the original document

I'm entirely unsure whether this would stress the processor - it's an
idea I haven't yet tried out.
