Tempore 23:03:47, die 08/05/2005 AD, hinc in xsl-list@xxxxxxxxxxxxxxxxxxxxxx scripsit Jacquo Johnson <genxgeek@xxxxxxxxx>:

	 <!-- 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 name="Filter">

indeed, there's an additional predicate missing: <xsl:copy-of select="$uh2[not(AttributeName=preceding::*[CodeId='30DAYPM']/AttributeName)]"/>

btw, here you have a sample using the Muenchian technique:

<xsl:key name="recordByC" match="Record" use="CodeId"/>
<xsl:key name="recordByCA" match="Record" use="concat(CodeId,AttributeName)"/>

<xsl:template match="/">
	<xsl:variable name="uh2" select="key('recordByC','30DAYPM')"/>
	<xsl:element name="Copy">
		<xsl:copy-of select="$uh2"/>
	<xsl:element name="Filter">
		<xsl:copy-of select="$uh2[generate-id()=generate-id(key('recordByCA',concat('30DAYPM',AttributeName))[1])]"/>
