You could do something like


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

  <xsl:variable name="list"
select="/inventory/product/node()[not(.=following::product/node())]" />

 
 	<product>
 		<xsl:copy-of select="$list"/>
	</product>

	</xsl:template>
	
</xsl:stylesheet>
