Hello everybody!

I have this template:

<xsl:template match="/">

<xsl:value-of select="file/entry/@id"/>

</xsl:template>

I need know if in the result there are repeated values and what they are.

You can use xsl:for-each-group and count the current-group() sequence:


<xsl:template match="/">
<xsl:value-of select="file/entry/@id"/>
<xsl:text>.</xsl:text>
<xsl:for-each-group select="file/entry/@id" group-by=".">
<xsl:variable name="count" select="count(current-group())"/>
<xsl:if test="$count &gt; 1">
<xsl:value-of select="concat(current-grouping-key(), ' repeated ', $count, ' times.')"/>
</xsl:if>
</xsl:for-each-group>
</xsl:template>
