RE: Grouping and numbering in XSLT 2.0,

Hi,
Thank you for the reply, I am sure this will do the job :-).

The v2.0 solution to this problem, could be nice to see. So, If someone
of you could show me, I would appreciate that.

You cannot use position() for the *use* expression of a key, it will
always return 1, but you can use something comparable, such as the count
of preceding-sibling nodes:


  <xsl:key name="company" match="*/cell[(_at_)name = 'Company']/value" 
    use="count(preceding-sibling::value) + 1"/>
  <xsl:key name="cage" match="*/cell[(_at_)name = 'Cage']/value" 
    use="count(preceding-sibling::value) + 1"/>
  <xsl:key name="address" match="*/cell[(_at_)name = 'Address']/value" 
    use="count(preceding-sibling::value) + 1"/>


A main template to get things going:


<xsl:template match="/">
  <Vendors>
    <xsl:call-template name="getVendors">
      <xsl:with-param name="count" select="1"/>
      <xsl:with-param name="total" 
                      select="count(*/cell[(_at_)name = 'Company']/value)"/>
    </xsl:call-template>
  </Vendors>
</xsl:template>


And a named template to call a number of times:


<xsl:template name="getVendors">
  <xsl:param name="count" select="1"/>
  <xsl:param name="total" select="1"/>

  <xsl:choose>
    <xsl:when test="$count &lt;= $total">
      <vendor>
        <cell name="Company">
          <value><xsl:value-of select="key('company', $count)"/></value>
        </cell>
        <cell name="Cage">
          <value><xsl:value-of select="key('cage', $count)"/></value>
        </cell>
        <cell name="Address">
          <value><xsl:value-of select="key('address', $count)"/></value>
        </cell>
      </vendor>
      <xsl:call-template name="getVendors">
        <xsl:with-param name="count" select="$count + 1"/>
        <xsl:with-param name="total" select="$total"/>
      </xsl:call-template>
    </xsl:when>

    <xsl:otherwise/>
  </xsl:choose>
</xsl:template>



There is probably a three-line v2.0 solution to this, but I've been out
of the loop lately.


HTH,

Mike
