 Hi John,
Please try the XSL -
<?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:param name="varDays" select="0"/>
<xsl:template match="/asx">
<xsl:variable name="rtf">
<xsl:for-each select="day[(last() - position())
< $varDays]">
<cl>
<xsl:value-of select="cl"/>
</cl>
</xsl:for-each>
</xsl:variable>
Moving Average = <xsl:value-of
select="sum(xalan:nodeset($rtf)/cl) div $varDays"/>
</xsl:template>
</xsl:stylesheet>
Regards,
Mukul
