Re: Interesting : Selecting unique value of an attribute

["Robert Stupak" <robert@xxxxxxxxxxx>]

Hello,

Don't know if that's the best way to do it but it works
if you include <index> elements into <something></something>

  <xsl:template match="something">
    <xsl:apply-templates select="index">
        <xsl:sort select="@entry"/>
    </xsl:apply-templates>
  </xsl:template>

  <xsl:template match="index">
    <xsl:if test="not(@entry = preceding::index/@entry)">
      <xsl:value-of select="@entry"/>
    </xsl:if>
  </xsl:template>
