Re: [xsl] Upon matching attribute value, increment output

[George Cristian Bina <george@xxxxxxx>]

Hi Russ,

You can count the number of preceding CON nodes with the same CODE 
attribute and if it is greater than zero output its value:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
    <xsl:output method="text"/>
    <xsl:template match="CON">
        <xsl:value-of select="@CODE"/>
        <xsl:variable name="precedingCodes" 
select="count(preceding-sibling::CON[@CODE=current()/@CODE])"/>
        <xsl:if test="$precedingCodes > 0">
            <xsl:text>_</xsl:text>
            <xsl:value-of select="$precedingCodes"/>
        </xsl:if>
    </xsl:template>
</xsl:stylesheet>

Best Regards,
George
