Re: Problem for : increment a variable in a for-each?

Hello,

may be I'm a bit clueless, but I can't figure out why you do all the
counting stuff. Have you tried  XPath expressions with predicates? I
guess, the following does what you are looking for.

Markus

<?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="/">
				<xsl:apply-templates/>
	</xsl:template>
<!-- the last one has to be <strong/> -->
	<xsl:template match="list[position() =last() and ParentID = '21']">
		<strong>
			<xsl:value-of select="Title"/>
		</strong>
	</xsl:template>
<!-- the second one has to be <italic/> -->
	<xsl:template match="list[position() = '2' and ParentID = '21']">
		<italic>
			<xsl:value-of select="Title"/>
		</italic>
	</xsl:template>
<!-- and another matcher... -->
	<xsl:template match="list[position() !=last() and ParentID = '21']">
		<whatever>
			<xsl:value-of select="Title"/>
		</whatever>
	</xsl:template>
</xsl:stylesheet>
