Re: Add products of two recursive additions

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>

Hello
I have two recursive addition functions producing totals which I would like
to add together.  How can I do this?

Eg To produce the first total I have used the xsl shown below:

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

The call-template above calls the template below to display the total for
'data':

<xsl:template name="orderlist.sum.edit">
<xsl:param name="set-of-order"/>
<xsl:variable name="sumorg">
<xsl:call-template name="orderlist.sum">
<xsl:with-param name="set-of-order" select="$set-of-order"/>
</xsl:call-template>
</xsl:variable>
<xsl:value-of select='format-number($sumorg, "£###,###,##0.00")'/>
</xsl:template>

<xsl:template name="orderlist.sum">
<xsl:param name="set-of-order"/>
<xsl:choose>
<xsl:when test="$set-of-order">
<xsl:variable name="first">
<xsl:apply-templates select="$set-of-order[1]/data"/>
</xsl:variable>
<xsl:variable name="rest">
<xsl:call-template name="orderlist.sum">
<xsl:with-param name="set-of-order" select="$set-of-order[position() !=
1]"/>
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="$first + $rest"/>
</xsl:when>
<xsl:otherwise>0</xsl:otherwise>
</xsl:choose>
</xsl:template>

The second total is acquired in the same way.  An example of the xml I am
using is also shown below:

<a>
<b>
 <c>
   <data>1</data>
 </c>
  <c>
   <data>3</data>
 </c>
 <d>
   <data>1</data>
 </d>
 <d>
  <data>5</data>
 </d>
 <d>
  <data>2</data>
 </d>
</b>
</a>

The two call-templates above refering to the recursive addition functions
produce the totals for <data> in <c> as 5 and <d> as 7. How do I obtain 12
as the total of both?

Thankyou very much for your help.
