if you want to avoid using node-set() then you will need a recursive
template to get you the total column width from which to calculate the
percentages.

To get rid of "in" etc. you can use
translate(@COLWIDTH,"abcdefghijklmnopqrstuvwxyz","") to get just the
numerical value.

  <xsl:template name="get_total_width">
    <xsl:param name="nodes" select="/.."/>
    <xsl:param name="sub_total" select="0"/>
    <xsl:variable name="width"
      select="number(
              translate($nodes/@COLWIDTH,
              'abcdefghijklmnopqrstuvwxyz',
      '')
      )"/>
      <xsl:choose>
        <xsl:when test="count($nodes) &gt; 1">
           <xsl:call-template name="get_total_width">
            <xsl:with-param name="nodes" select="$nodes[position() != 1]"/>
              <xsl:with-param name="sub_total" select="$sub_total +
$width"/>
            </xsl:call-template>
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="$sub_total + $width"/>
          </xsl:otherwise>
        </xsl:choose>
      </xsl:template>

then you can call it to get the total for the table you're looking at:


<xsl:variable name="total_width">
   <xsl:call-template name="get_total_width">
      <xsl:with-param name="nodes" select="TGROUP/COLSPEC[(_at_)COLNUM]"/>
   </xsl:call-template>
</xsl:variable>


and as long as the variable's in scope, use it to calculate the percentage.


thanks! I will give that a try tomorrow.

Thanks also to the others that replied. Unfortunately I can't do the twopass thing either as the data on the PC is on a DVD whilst the data on themac is on the disk. Also both machines have an entirely different diskstructure so the problem with external files is that the location of themare different.


Oh, the joys of cross platform standardised languages :)
