Hello,
try the example below.
Note, that it is not necessary to use node-set()
extension function in case of saxon (does conversion
automatically).
Best regards
Jirka
XML
<box>
<item><qty>2</qty><price>3</price></item>
<item><qty>3</qty><price>4</price></item>
<item><qty>5</qty><price>6</price></item>
</box>
XSLT
<xsl:stylesheet
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
xmlns:saxon="http://icl.com/saxon" extension-element-prefixes="saxon"
version="1.0">
<xsl:template match="/box">
<xsl:variable name="all">
<xsl:apply-templates select="/box/item" mode="qty_times_price"/>
</xsl:variable>
<result>
<xsl:value-of select="sum(saxon:node-set($all)/tmp)"/>
</result>
</xsl:template>
<xsl:template match="item" mode="qty_times_price">
<tmp><xsl:value-of select="qty*price"/></tmp>
</xsl:template>
</xsl:stylesheet>
Output:
<?xml version="1.0" encoding="utf-8"?>
<result>48</result>
Best regards
Jirka
