[xsl] removing duplicates from sorted list

Hi,

I think the for-each has to check each target character id node with
every other one and not just the preceeding one, so I've tried
'preceding' and 'ancestor' to check all up to the root but the
duplicates are still there...anyone?

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

<xsl:template match ="/"> 
<html> 
<body> 
<xsl:for-each select="LOG/DIRECT/TARGET_CHARACTER_ID[. != 
preceding-sibling::TARGET_CHARACTER_ID]"> 
<xsl:sort select="." data-type="number" 
order="ascending" /> 
<xsl:value-of select="position()" /><xsl:value-of 
select="." /> 
</xsl:for-each> 
</body> 
</html> 
</xsl:template> 
</xsl:stylesheet> 

My xml doc looks like this:-

<LOG>
      <DIRECT>
      <COMMUNICATION_TYPE> PAGETELL </COMMUNICATION_TYPE>
      <Invoc_serial> 27 </Invoc_serial>
      <Serial> 3087908 </Serial>
      <USAGE> TELL </USAGE>
      <MESSAGE_TYPE> EMOTE </MESSAGE_TYPE>
      <CHARACTER_ID> 44639 </CHARACTER_ID>
      <CHARACTER_STATUS> 3 </CHARACTER_STATUS>
      <LOCATION_ID> 45040 </LOCATION_ID>
      <TARGET_CHARACTER_ID> 2346456 </TARGET_CHARACTER_ID>
      <TARGET_CHARACTER_STATUS> 6 </TARGET_CHARACTER_STATUS>
      <TARGET_CHARACTER_LOCATION_ID> 23222
</TARGET_CHARACTER_LOCATION_ID>
      <MESSAGE>hello</MESSAGE>
      <TIME> 'Mon, 26 Nov 2001 15:40:29 +0000' </TIME>
      </DIRECT>

*then a few hundred more like that*

</LOG>
