There seems to be no need to use nodeset function. You
can simply write the XSL as below -
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html" indent="yes" />
<xsl:template match="/root">
<xsl:apply-templates select="currentnode" />
</xsl:template>
<xsl:template match="currentnode">
<p><xsl:value-of
select="sum(preceding-sibling::sibling/@value)" /></p>
</xsl:template>
</xsl:stylesheet>
When the above XSL is applied to XML -
<?xml version="1.0" encoding="UTF-8"?>
<root>
<sibling value="5"/>
<sibling value="7"/>
<sibling value="9"/>
<sibling value="13"/>
<currentnode>some text</currentnode>
</root>
the o/p recieved is -
<p>34</p>

will this work with xalan? because i tried to use
something like this and it gave me an error.
also i tried using this
<xsl:template match="currentnode"
...
...
<xsl:variable name="Total">
<xsl:for-each
select="preceding-sibling::sibling[(_at_)value]">
<SubTotal>
<xsl:value-of select="(@value)"/>
</SubTotal>
</xsl:for-each>
</xsl:variable>
<p>
<xsl:value-of
select="sum(xalan:nodeset($Total)/SubTotal)"/>
<br/>
</p>
</xsl:template>
and it gives me an error
"function not in namespaceError in Xpath expression,
function not in namespace"
Please let me know.
Thanks,

Subject: [xsl] Calculating Sum in XSLT 1.0
I am trying to generate a sum of attribute
values
of
sibling nodes via XSLT 1.0
My XML looks like this
<sibling value="5"/>
<sibling value="7">
<sibling value="9">
<sibling value="13">
<currentnode>some text</currentnode>
When I am processing the template for
currentnode
I
want to calculate the sum of the "value"
attribute
of
all its previous sibling nodes i.e. I want to
find
the
sum of 5,7,9 and 13. The names of the sibling
node
and
current node are different.
I know there isn't a direction function to do
this. If
anyone has written template or come accross the
problem then please let me know how did you
solve
it.
Thank you for your help and Merry Christmas.
Abhi
