Re: Validating uniqueness in a XML file using XSLT

Use something like this:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:output omit-xml-declaration="yes" indent="yes"/>

  <xsl:key name="kattName" match="@name" use="."/>

  <xsl:template match="/">
    <xsl:for-each select="//*[key('kattName', @name)[2]]">
      <xsl:copy>
        <xsl:copy-of select="@*"/>
      </xsl:copy>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

When this transformation is applied on this source.xml:

<M name="a">
  <N> </N>
  <M name="b">
    <N name="a"> 12</N>
    <MM name="c"/>
  </M>
</M>

it produces all elements having "name" attributes with non-unique value:

<M name="a" />
<N name="a" />
