RE: [xsl] how calculate sum(x*y)

["Andrew Welch" <awelch@xxxxxxxxxxxxxxx>]

You could create an RTF of <data> elements with the first part of the
sum done:

<xsl:variable name="data">
  <xsl:for-each select="/root/data">
  <data>
    <xsl:attribute name="sumXY">
      <xsl:value-of select="x * y"/>
    </xsl:attribute>
  </data>
  </xsl:for-each>
</xsl:variable>

(which would give you <data sumXY="6"/> .....)

Then when you want the sum of all (x * y) you can just sum on the RTF:

<xsl:value-of select="sum(exsl:node-set($data)/data/@sumXY)"/>
