Jeni's grouping example helped me solve a similar problem
(http://www.jenitennison.com/xslt/grouping/muenchian.html).

But I think you could simplify it a bit to remove duplicates:

<xsl:key name="uq" match="hdl" use="@id" />

<xsl:template match="some-element">
    <xsl:for-each select="hdl[count(.|key('uq', @id)[1]) = 1]">
       <mod><xsl:value-of select="@id"/></mod>
          <xsl:for-each select="key('uq', @id)"/>
    </xsl:for-each>
</xsl:template>

Hi All,

I want to remove duplicate nodes by looking at an attribute (in this case
id).  Can anyone suggest a good way to do this.
