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[@COLNUM]"/>
   </xsl:call-template>
</xsl:variable>

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