[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Correct syntax for removing duplicates from sorted lis
 Hi,
I am trying to remove duplicate copies of context nodes from a sorted
list. 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>
My xml stylesheet as is looks like this:-
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html"/>
<xsl:variable name="last">
</xsl:variable>
<xsl:template match ="/">
<xsl:for-each select="LOG/DIRECT/TARGET_CHARACTER_ID">
<xsl:variable name="last" select="LOG/DIRECT/TARGET_CHARACTER_ID"/>
<xsl:sort select="." data-type="number"/>
<xsl:value-of select="position()"/>
<xsl:text>. </xsl:text>
<html>
<body>
<xsl:if test=not".=last">
<xsl:value-of select="."/><br></br>
</xsl:if>
</body>
</html>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
And my sorted but duplicated output is something like this:-
1. 23220
2. 23470
3. 23470
4. 23470
5. 23470
6. 23470
7. 23470
8. 83470
9. 212120
10. 223232
11. 231212
12. 2346456
13. 27675340
So every time I get to the context node(in this case "TARGET_CHARACTER_ID")
I need to check if it matches the previous one and if so NOT to output it.
This
should give me a unique list rather than a total occurences count.
The code as is (oops!) just tests to see if it equals itself I think! and
I've been looking
at axis but as I am comparing .=. then I'm not sure the best way to proceed,
as I
need to test with the previous 'iteration' as it were.
Any help gratefully received!
Cheers
Ahmad (p.s cheers Jen and Chris for your previous help)
