Subject: Need help on XSL query
Hello,
I need to display the sum of sales for each country only once! Current code is
not properly working and I understand it is because the loop itself is to
select all possible "@country" occurences but I also tried to use set:distinct
but am getting error like "set function not found in namespace...". Could
someone help me out in resolving this problem? Here is the template I have
written:
===============================================
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:key name="locations" match="location" use="@country" />
<xsl:template match="/">
<html>
<body>
<table>
<xsl:for-each select="//@country">
<xsl:variable name="country">
<xsl:value-of select="." />
</xsl:variable>
<xsl:variable name="Total">
<xsl:value-of select="sum(key('locations',$country)/sales)" />
</xsl:variable>
<xsl:value-of select="$country" />
<xsl:value-of select="$Total" /> <br/>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
XML FILE IS
===========
<SalesDB>
<time year="1996" quarter="1">
<product category="Ford" brand="Escort">
<location country="USA" state="NY">
<sales>70</sales>
</location>
<location country="USA" state="CA">

<location country="Canada" state="Ontario">

<location country="Canada" state="British Columbia">

</location>
</product>
.........continue........
