RE: sum() of nodeset

[Shimon Pozin <shimonp at servicesoft dot com>]

Thanks again for the answer!
One more problem, however. In my original mail I simplified
the question taking m=1 as a parameter:
-------------------xsl------------------------
<xsl:for-each select="//row[@m=1]">
    <tr>
       <td><xsl:value-of select="@m" /></td>
       <td><xsl:value-of select="@y" /></td>
       <td><xsl:value-of select="@v" /></td>
    </tr>
</xsl:for-each>
----------------------------------------------
How can I build this table for all different m's? Is there a way
to do a loop from 1 to 12 somehow? I cannot figure this out.
Again, your help is invaluable!
