Re: [xsl] Enumerating template matches

[Joerg Heinicke <joerg dot heinicke at gmx dot de>]

Either

<xsl:template match="B">
   <xsl:apply-templates select="C">
     <xsl:with-param name="match_number" select="position()"/>
   </xsl:apply-templates>
</xsl:template>

<xsl:template match="C">
   <xsl:param name="match_number"/>
   <xsl:value-of select="$match_number"/>
</xsl:template>

or

<xsl:template match="C">
   <xsl:value-of select="count(../preceding-sibling::B) + 1"/>
</xsl:template>

Regards,

Joerg
