Re: "sum" of "substring"

Hi Colin,
Sorry for coming in late to answer..

If I understood the problem correctly, *the following
XSL hopefully solves the problem* ..

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xalan="http://xml.apache.org/xalan";>
<xsl:output method="text" version="1.0"
encoding="UTF-8" indent="yes"/>

<xsl:template match="/records">
   <xsl:variable name="xml-subset">
      <xsl:for-each select="record">
        <xsl:if test="substring(. , 1, 5) = 'TYPE1'">
           <a>                   
            <xsl:value-of select="substring(. , 24, 5)"/>
           </a> 
        </xsl:if>
      </xsl:for-each>
   </xsl:variable>
                
   Desired total -- <xsl:value-of
select="sum(xalan:nodeset($xml-subset)//a)" />
</xsl:template>

</xsl:stylesheet>

I am assuming, the following XML is already written --

<?xml version="1.0" encoding="UTF-8"?>
<records>
  <record>TYPE1Field1AnotherField12.5
YetAnotherField445.26FinalField</record>
  <record>TYPE1ABCDEFABCDEFGHIJKL13.0
ABCDEFGHIJKLMNO123.45ABCDEFGHIJ</record> 
  <record>TYPE2FieldAnother987.65Final</record>
</records>

When the XSL posted by me, is applied to the XML, the
desird sum is produced. I am using, *the nodeset
extension function*, and have introduced a Result Tree
Fragment(RTF), with a XML element <a> , for the sake
of computation..

Hope my answer is useful..

Regards,
Mukul
