Re: [xsl] Grouping problem?

["Simon Kelly" <kelly@xxxxxxxxxx>]

Damn it again!!

Here is the tail recursion version!!

<xsl:template match="ele">
  <xsl:choose>
    <xsl:when test="position() = 1">
      <xsl:variable name="count" select="sum(./@sum)" />
    </xsl:when>
    <xsl:when test="$count < 10">
      <xsl:choose>
        <xsl:when test="($count + sum(./@sum)) >= 10">
          <br/>
          <xsl:variable name="count" select="sum(./@sum)" />
        </xsl:when>
        <xsl:otherwise>
          <xsl:variable name="count" select="$count + sum(./@sum)" />
        </xsl:otherwise>
      </xsl:choose>
    <xsl:otherwise>
      <br />
      <xsl:variable name="count" select="sum(./@sum)" />
    </xsl:otherwise>
  </xsl:choose>
  <xsl:copy>
    <xsl:apply-templates select="node()|@*" />
  </xsl:copy>
</xsl:template>

Cheers

Simon
