Re: [xsl] variable going out of scope in a for-each loop?

Eric -

If it's always the last two nodes that you want to multiply, then it's
pretty straight forward:

<xsl:value-of select="cell[last()-1] * cell[last()]"/>

(where row is the current node).

If you just want the product of all nodes that are numbers, you have to use
a recursive process.  You can start by selecting all number nodes by using a
select expression similar to the xsl:if you used:  <xsl:variable
name="numberNodes" select="cell[number(.)=number(.)]"/>  (replace
xsl:variable with xsl:with-param to pass it to your recursive template).

Alternately, if it's possible to use extension functions and you're using
Saxon, I'm sure Mike has one that'll make this job a piece of cake.  I'll
leave it to him (or whoever else steps up) to give that to you.

Hope that helps.
