Re: [xsl] Add products of two recursive additions

[Josh Canfield <joshcanfield@xxxxxxxxx>]

If the structure is as you have described, then why not use sum()?

  <xsl:template match="/">
  <sums>
    c/data: <xsl:value-of select="sum(a/b/c/data)"/>
    d/data: <xsl:value-of select="sum(a/b/d/data)"/>
    all : <xsl:value-of select="sum(a/b/c/data | a/b/d/data)"/>
  </sums>
  </xsl:template>

If you do need the recursive addition then change the template to
return un-formated numbers, store them in variables and add them
together. Or, less efficiently, you could just pass all the nodes to
your existing functions like this:


<xsl:template match="/">
  <xsl:variable name="cd">
    <xsl:call-template name="orderlist.sum.edit">
      <xsl:with-param name="set-of-order" select="/a/b/d | /a/b/c"/>
    </xsl:call-template>
  </xsl:variable>
  <cd>
    <xsl:value-of select="$cd"/>
  </cd>
</xsl:template>
