Re: [xsl] XSLT Grouping/Filtering issue with preceding/following axes

[Jacquo Johnson <genxgeek@xxxxxxxxx>]

Hi Joris,

Thanks for pointing that out.  However, after fixing typo for some
reason the stylesheet is still not filtering/grouping correctly per
the following (especially the last <CodeId/> in the input xml file).:

Any idea as to what is going on here?  Thanks!

XSL:

	<xsl:template match="/">
	
		<xsl:element name="Root"> 
		
<!-- Ok, this works for FRED as the group is filtered with no duplicates -->
  <xsl:variable name="uh" select="//Record[CodeId='FRED']"/>
  <xsl:element name="Copy">
      <xsl:copy-of select="$uh"/>
   </xsl:element>
   <xsl:element name="Filter">
      <xsl:copy-of
select="$uh[not(AttributeName=preceding::*/AttributeName)]"/>
   </xsl:element> 

	 <!-- However, this does not work for the 30DAYPM as it is missing
the LT CodeId group -->
  <xsl:variable name="uh2" select="//Record[CodeId='30DAYPM']"/>
  <xsl:element name="Copy">
      <xsl:copy-of select="$uh2"/>
   </xsl:element>
   <xsl:element name="Filter">
      <xsl:copy-of
select="$uh2[not(AttributeName=preceding::*/AttributeName)]"/>
   </xsl:element> 
	 
   <!-- This works but I'm sure is not the best way to do this... -->
  <xsl:variable name="uh" select="//Record[CodeId='30DAYPM']"/>
  <xsl:element name="Copy">
      <xsl:copy-of select="$uh"/>
   </xsl:element>
   <xsl:element name="Filter">
      <xsl:copy-of
select="$uh[(not(AttributeName=preceding::*/AttributeName) and
          position()=1) or (not(AttributeName=following::*/AttributeName))]"/>
