Subject: Re: [xsl] Find the node with maximum elements From: "G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx> Date: Sun, 04 Nov 2007 08:23:11 -0500 |
The following solution is likely more efficient than Ken's (because, it calculates 'max' only once):
You can optimize the speed by putting the max value into a variable and testing against that
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="text" />
<xsl:template match="/Sample"> <xsl:variable name="max-count" select="max(*/count(Car))" /> <xsl:for-each select="*"> <xsl:if test="count(Car) = $max-count"> <xsl:value-of select="local-name()" /><xsl:text> </xsl:text> </xsl:if> </xsl:for-each> </xsl:template>
</xsl:stylesheet>
T:\ftemp>type avaneesh.xml <Sample> <Toyota> <Car>Camry</Car> <Car>Corrola</Car> </Toyota> <Honda> <Car>Accord></Car> <Car>Civic</Car> <Car>Pilot</Car> </Honda> <Mitsubishi> <Car>Lancer</Car> <Car>Lancer</Car> <Car>Lancer</Car> </Mitsubishi> <Hyundai> <Car>Sonata</Car> <Car>Accent</Car> </Hyundai> </Sample>
T:\ftemp>type avaneesh.xsl <?xml version="1.0" encoding="US-ASCII"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:template match="/"> <xsl:variable name="max" select="max(/Sample/*/count(Car))"/> <xsl:value-of select="/Sample/*[count(Car)=$max]/name(.)" separator="
"/> </xsl:template>
</xsl:stylesheet> T:\ftemp>xslt2 avaneesh.xml avaneesh.xsl con Honda Mitsubishi T:\ftemp>type avaneesh2.xsl <?xml version="1.0" encoding="US-ASCII"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:template match="/"> <xsl:value-of select="/Sample/*[count(Car)=max(/Sample/*/count(Car))] /name(.)" separator="
