Hi Brian,
Please try -

<?xml version="1.0"?> 
<xsl:stylesheet

xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

version="1.0">



<xsl:output method="text" /> 



<xsl:template match="/a">
  <xsl:value-of select="(b[1]/c * b[1]/d) + (b[2]/c *
b[2]/d)" />
</xsl:template>

</xsl:stylesheet>



 



Thanks... looks like there's no generic way to do it with xpath 1.0 as 
Michael suggested.

I'm roped into perl XML::LibXSLT for this particular project, so it 
looks like a recursive template. :-)



thanks,
Brian

Regards,
Mukul

Uggg... I had some sloppy cut-paste issue in my last
post... this is what it should have been, with a
real subject line.  Sorry...

-----------------------
Okay.. I told someone I could do this in a simple
xpath expression

<?xml version="1.0"?>
<a>
 <b>
   <c>2</c>
   <d>4</d>
 </b>
 <b>
   <c>3</c>
   <d>6</d>
 </b>
</a>

Where the xpath was to return (2*4) + (3*6) = 26

I made several attempts with xpath's sum() function

(using 1.0) and 
couldn't get it.

I couldn't even come up with an expression that I

thought might work.. 
even though I tried several which I was certain

would fail (which did).



Any ideas?
