Generate-id not working

Question

Within XSLT, the generate-id function is supposed to generate a unique id for each node. This does not seem to be working in Oracle. Here is the code:
PROCEDURE GENERATE_ID AS
queryCtx DBMS_XMLquery.ctxType;
xmldoc CLOB;
     xsldoc          CLOB;
myParser dbms_xmlparser.Parser;
xsltdomdoc dbms_xmldom.domdocument;
xsl dbms_xslprocessor.stylesheet;
outdomdocf dbms_xmldom.domdocumentfragment;
outnode dbms_xmldom.domnode;
proc dbms_xslprocessor.processor;
buf varchar2(200);
BEGIN
     xmldoc := '
     <ROWSET>
          <ROW><DIM_NAME>DIM_ONE</DIM_NAME></ROW>
          <ROW><DIM_NAME>DIM_TWO</DIM_NAME></ROW>
          <ROW><DIM_NAME>DIM_TWO</DIM_NAME></ROW>
          <ROW><DIM_NAME>DIM_THREE</DIM_NAME></ROW>
          <ROW><DIM_NAME>DIM_THREE</DIM_NAME></ROW>
     </ROWSET>
     xsldoc := '
     <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
          <xsl:template match="/">
               <xsl:for-each select="ROWSET/ROW"><xsl:value-of select="generate-id(.)"/>|</xsl:for-each>
          </xsl:template>
     </xsl:stylesheet>
myParser := dbms_xmlparser.newParser;
dbms_xmlparser.parseBuffer(myParser, xsldoc);
xsltdomdoc := dbms_xmlparser.getDocument(myParser);
xsl := dbms_xslprocessor.newstylesheet(xsltdomdoc, '');
proc := dbms_xslprocessor.newProcessor;
outdomdocf := dbms_xslprocessor.processxsl(proc, xsl, xmldoc);
outnode := dbms_xmldom.makenode(outdomdocf);
dbms_xmldom.writetobuffer(outnode, buf);
dbms_output.put_line(buf);
END;
The output is:
ID0|ID0|ID0|ID0|ID0|
If I try this with MSXML3 or ColdFusion, I correctly get unique id's for each node. This error makes using the standard Muenchian grouping method fail.
For example, this XSLT:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:key name="DimNameKey" match="/ROWSET/ROW" use="DIM_NAME"/>
<xsl:template match="/">
<xsl:for-each select="ROWSET/ROW[generate-id(.) = generate-id(key(''DimNameKey'',DIM_NAME)[1])]">
<xsl:value-of select="DIM_NAME"/>|</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
should generate:
DIM_ONE|DIM_TWO|DIM_THREE|
but instead it generates:
DIM_ONE|DIM_TWO|DIM_TWO|DIM_THREE|DIM_THREE|
Is there some way I can work around this?
I am running Oracle 9.2.0.3.0 - Production on Windows XP Professional.

Answer 1

The transformation works correctly when used with DBMS_XMLQuery.SETXSLT. So I can at least use that method instead.
