Re: endless rekursion

I guess, the following XSL will be appropriate --

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
	
<xsl:template match="/CheckBoxQuestion">
    <xsl:variable name="right" 
select="count(option/solution[@valid_input = '1'])" />
    <xsl:variable name="wrong" 
select="count(option/solution[@valid_input = '0'])"/>
	    
    Total points: <xsl:value-of select="$right -
$wrong" />
</xsl:template>

</xsl:stylesheet>

Regards,
Mukul
