RE: XML criterias

Hey Michael,

	Thank you so much! Didnt even occur to me to use a recursive
template.
And thanx for the correction on criteria as well. My excuse is that the SATs
is a distant memory. :-P

I think you need a recursive template that applies a filter for one
criterion on each iteration.

<xsl:template name="filter">
  <xsl:param name="nodes"/>
  <xsl:param name="criteria"/>
  <xsl:choose>
  <xsl:when test="$criteria">
    <xsl:variable name="criterion" select="$criteria[1]"/>
    <xsl:call-template name="filter">
      <xsl:with param name="criteria" select="criteria[position()>1]"/>
      <xsl:with param name="nodes" 
        select="$nodes[@*[name()=$criterion/@name and
.=$criterion/c:value]"/>
    </
  </xsl:when>
  <xsl:otherwise>
      <xsl:copy-of select="$nodes"/>
  </
  </xsl:choose>
</

(PS, just saw your title. Call me old-fashioned, but in my dictionary
you have one criterion, two criteria)
