Being a complete xsl tyro as I am, I know I'm making some sort of conceptual error. This is clearly the wrong way to go about this. Has anybody got a clue for the clueless?

Starting with an xml file like this:
<body>
	<item>
		<date>today</date>
		<name>James</name>
		<place>market</place>
	</item>
	<item>
		<date>today</date>
		<name>Joe</name>
		<place>work</place>
	</item>
	<item>
		<date>today</date>
		<name>Joe</name>
		<place>school</place>
	</item>
	<item>
		<date>tomorrow</date>
		<name>Jean</name>
		<place>home</place>
	</item>
	<item>
		<date>thenextday</date>
		<name>Jon</name>
		<place>work</place>
	</item>
</body>

This is the result I want to get:
<body>
	<today>
		<item>
			<date>today</date>
			<name>James</name>
			<place>market</place>
		</item>
		<item>
			<date>today</date>
			<name>Joe</name>
			<place>work</place>
		</item>
		<item>
			<date>today</date>
			<name>Joe</name>
			<place>school</place>
		</item>
	</today>
	<tomorrow>
		<item>
			<date>tomorrow</date>
			<name>Jean</name>
			<place>home</place>
		</item>
	</tomorrow>
	<thenextday>
		<item>
			<date>thenextday</date>
			<name>Jon</name>
			<place>work</place>
		</item>
	</thenextday>
</body>

Using the Muenchian method, I've been able to identify unique values for item/date thus: <xsl:key name="items" match="item" use="date"/> <xsl:template match="/"> <xsl:param name="uniquedates" select="//item[generate-id(.)=generate-id(key('items',date))]"/> <xsl:for-each select="$uniquedates"> <xsl:element name="{string(date)}"> <xsl:copy-of select="."/> </xsl:element> </xsl:for-each> </xsl:template>

But, since $uniquedates returns a node set containing only three nodes, I can't figure out how to populate the new elements with all of its appropriate children, so I get this: <body> <today> <item> <date>today</date> <name>James</name> <place>market</place> </item> </today> <tomorrow> <item> <date>tomorrow</date> <name>Jean</name> <place>home</place> </item> </tomorrow> <thenextday> <item> <date>thenextday</date> <name>Jon</name> <place>work</place> </item> </thenextday> </body> I know I'm missing something obvious here. Any sort of clue would be welcome. __________ J.J. Crump Dept. of History 353560 University of Washington Seattle, WA. 98195
