Hi, how to a get a total numerical value of attributes from siblings? I need to get the total value of all the colspec/@colwidth that are a child of tgroup. Here is some code.

xml sample

Code:

<tgroup cols="2" colsep="1" rowsep="1">
              <colspec colnum="1" colname="col1" colwidth="12pi" colsep="1" rowsep="1"/>
              <colspec colnum="2" colname="col2" colwidth="12pi" colsep="1" rowsep="1"/>
               <thead>
......

XSLT Template

Code:

<xsl:template match="colspec">
    <xsl:variable name="total">
        <xsl:choose>
            <xsl:when test="contains(../colspec/@colwidth, 'pi')">
                <xsl:value-of select="sum(number(substring-before(../colspec/@colwidth, 'pi')))"/>
            </xsl:when>
            <xsl:otherwise>
                <xsl:value-of select="number(0)"/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:variable>
    <!--to do-->
</xsl:template>

Thanks for the help

This one is easy in XSLT 2.0, hard in 1.0.

In 2.0

sum(for $x in ../colspec/@colwidth return number(substring-before($x, 'pi')))

For some of the approaches possible in XSLT 1.0, see http://www.dpawson.co.uk/xsl/sect2/N...tml#d6610e1271
