Hi, I'm fairly new to XSLT and have been having a problem with an XML file
I'm trying to process, the file being something along the lines below

	<?xml version="1.0"?>
	<?xml-stylesheet type="text/xsl" href="andytest.xsl"?>
	<Resources>
		<resource>
			<filename Dept="A" LastModified="10/03/2003"
NextReview="10/04/2003" Stale="More Than Month Overdue">
				Filename title
			</filename>
			<author>
				Joe
			</author>
			<readers/>
			<Div Head>
				A
			</Dept Head>
			<Division>
				A
			</Division>
		</resource>
		<resource>
			<filename Dept="A " LastModified="30/04/2003 14:02 "
NextReview="31/05/2003 " Stale="Up To Month Overdue">
				Filename title
			</filename>
			<author>
				Jill 
			</author>
			<readers/>
			<Div Head>
				 Person B
			</Div Head>
			<Division>
				Div B 
			</Division>
		</resource>
		<resource>
			<filename Dept="A" LastModified="17/04/2003"
NextReview="29/05/2003" Stale="Up To Month Overdue">
				Filename title
			</filename>
			<author>
				Sam
			</author>
			<readers/>
			<Div Head>
				Person C	
			</Div Head>
			<Division>
				A
			</Division>
		</resource>
		<resource>
			<filename Dept="B" LastModified="30/05/2003"
NextReview="01/07/2003" Stale="More Than Week To Go">
				Filename Title
			</filename>
			<author>
				Alice
			</author>
			<readers>
				<reader count="1">
					Bloggs J (Joe)
				</reader>
				<reader count="1">
					Bloggs S (Sam)
				</reader>
				<reader count="1">
					Bloggs J (Jim)
				</reader>
			</readers>
			<Div Head>
				Person A
			</LeadMinister>
			<Division>
				C
			</Division>
		</resource>
	</Resources>




need to end up with 

Group by Dept: Group By Division: Group By Author


Dept	-	Division	-	Author
----------------------------------------------
A	-	A		-	Joe   
	-			-	Sam
	-	B		-	Jill

B	-	C		-	Alice

The problem I'm having is I'm trying to use Meunchian grouping and while I
can get the first grouping using

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns="http://www.w3.org/1999/xhtml"; version="1.0">
<xsl:output indent="yes" method="html"/>

<xsl:key name="resources-div" match="resource" use="Division" />


<xsl:template match="/">
<html>
<head></head>
<body>
<xsl:apply-templates />
</body>
</html>
</xsl:template>

<xsl:template match="Resources">
<xsl:for-each
select="//resource[generate-id(.)=generate-id(key('resources-div',Division))
]">
<xsl:value-of select="Division" />

<xsl:for-each select="key('resources-div',Division)">
</xsl:for-each>

</xsl:for-each>

</xsl:template>


</xsl:stylesheet>

I'm having great trouble getting the second grouping and so on to work, I've
experimented with a few different formats but haven't quite got there (or
got there at all) so I was hoping someone would be able to give me a few
pointers to get me in the right direction.
