Re: Generating serial no.s for XML tags

I'd try with a recursive approach. Try the stylesheet below. It may be overly complex since I'm quite new to XSLT.

/Marcus

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="rootelem">
  <xsl:call-template name="doTag">
    <xsl:with-param name="nodes" select="tag"/>
    <xsl:with-param name="currentValue">0</xsl:with-param>
  </xsl:call-template>
</xsl:template>

<xsl:template name="doTag">
  <xsl:param name="nodes"/>
  <xsl:param name="currentValue"/>
  <xsl:value-of select="$currentValue + 1"/>
  <xsl:choose>
    <xsl:when test="$nodes[1]/total">
      <xsl:value-of select="$currentValue + 2"/>
      <xsl:if test="count($nodes) &gt; 1">
        <xsl:call-template name="doTag">
          <xsl:with-param name="nodes" select="$nodes[position() != 1]"/>
          <xsl:with-param name="currentValue" select="$currentValue + 2"/>
        </xsl:call-template>
      </xsl:if>
    </xsl:when>
    <xsl:otherwise>
      <xsl:if test="count($nodes) &gt; 1">
        <xsl:call-template name="doTag">
          <xsl:with-param name="nodes" select="$nodes[position() != 1]"/>
          <xsl:with-param name="currentValue" select="$currentValue + 1"/>
        </xsl:call-template>
      </xsl:if>    
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

</xsl:stylesheet>
