I have a sequence and want to know whether there are duplicate values in it.
I came out with the following and think there must be an easy solution. Any
suggestion?
let $sequence :=(1,12,14,17,22,12) return (count(distinct-values($sequence))
ne count($sequence))
I think is fine to compare the count, and
http://www.xsltfunctions.com/xsl/functx_are-distinct-values.html has the same
idea basically
<xsl:function name="functx:are-distinct-values" as="xs:boolean"
xmlns:functx="http://www.functx.com";>
<xsl:param name="seq" as="xs:anyAtomicType*"/>
<xsl:sequence select="
count(distinct-values($seq)) = count($seq)
"/>
</xsl:function>
