Re: [xsl] recursive counter not incrementing

[Christopher Hansen <chansen1@xxxxxxxxx>]

David, 
Thanks for suggesting the count/union operation...i researched it a
little bit and it makes complete sense, however i must be doing
something wrong because its not returning TRUE when it should be...see
the IF statement in the subset template below.  I've reminded you how
i initialized $s1 and $s2 in the main template....


 <!--using the 2nd transaction...-->
 <xsl:variable name="transitems1"
select="document('transactions.xml')//transaction[2]" />
 
<xsl:output method="html"/>
  <xsl:template match="/">

      <!-- set1 = 1st itemset consisting of 3 items Milk, Butter, Eggs
(using itemsets.xml)-->
      <xsl:variable name="set1" select= "frequent_item_sets//set[1]" />
      <!-- set2 = 2nd transaction, 11 items (Milk, Butter, and Eggs
among them) -->
      <xsl:variable name="set2" select="$transitems1/items" />

          <!--output both sets-->
          <xsl:value-of select="$set1"/>
          <xsl:value-of select="$set2"/>
      
      <xsl:call-template name="subset">
           <xsl:with-param name="s1" select="$set1"/>
           <xsl:with-param name="s2" select="$set2"/>
      </xsl:call-template>

<xsl:template name="subset">
     <xsl:param name="s1"/>
     <xsl:param name="s2"/>
  
    <xsl:value-of select="count($s1/item)"/> <!--shows '3' -->
    <xsl:value-of select="count($s2/item)"/> <!--shows '11'-->
 
    <!--following is not executing-->
    <xsl:if test="count($s1/item|$s2/item)=count($s1/item)">
        <b>S1 is a subset of S2.</b>
    </xsl:if>

</xsl:template>
