[xsl] sum and substring xpath needed

["Andrew Welch" <awelch at piper-group dot com>]

Hi all,

Please can someone give me the xpath that will sum() the following
values into the select attribute of a variable (ie not a rtf).

<colspec colwidth="38mm"/>
<colspec colwidth="22mm"/>
<colspec colwidth="26mm"/>
<colspec colwidth="43mm"/>

so something like:

<xsl:variable name="total" 
  select="sum(substring-before(//tgroup/colspec/@colwidth,'mm'))"/>

..this obviously fails because sum() requires a node-set and the
substring functions return strings, but you get the idea.  I dont think
its possible to do in a single select but you never know, hopefully
there's some trick available.

cheers
andrew
