Re: [xsl] Accumulating Sum ( Sum Across Rows)

["KUMAR NINGASHETTY" <kningashetty@xxxxxxxxxxxxxxxx>]

Here is the XSL snippet i am using and adopting the sum() function you specified . It doesnt give me the sum rather
it gives me the concatenation of numbers across the rows... For example in this XML example it gives 41 instead of
5 ( 4+1) 
can you throw some solution on this again to calculate SUM across ROWS  ..I am attaching XML again if anyone wanna
take a look at it ...
Note : pete , I have changed XML slightly to look simple ...

<!-- XSL snippet -->

<xsl:key name="distinct-region"  match="//company/vehicle/region/region_name"  use="text()"/>

<xsl:template match="/" >

 <xsl:for-each select="//company/vehicle/region/region_name[generate-id()=generate-id(key('distinct-region', text()))]">

    <xsl:variable name="sumN">
           <xsl:for-each select="key('distinct-region', text())">

	     <xsl:variable name="uid"	select="ancestor::vehicle/@id"/>
                    <xsl:value-of select="sum(ancestor::data/review/vehicle[@idref=$uid)"/>

        </xsl:for-each>
     </xsl:variable>

     <xsl:value-of select="$sumN"/>

 </xsl:for-each>
</xsl:template>


<!--  XML -->
<data>
 <company>
 	<vehicle id="768">
		<region >
		     <region_name><![CDATA[Region 4]]></region_name>

	</vehicle>

 <review>

 </review>
</data>

Check whether the sum() function solves your problem.
Try something like
   <xsl:variable name="totalN" select="vehicle/count[type='N']"/>
and use the variable.
