[xsl] table/matrix and xpath prob

[m.vanrootseler@xxxxxxxxx]

I'm battling with the following problem. I have two xml-files; on one
I'm doing the transformation and the other one is imported with
document(). The structure of the first file is as follows:

<variables>
	<variable>
		<word>X</word>
		<variants>
			<variant>
				<word>foo</word>
				<locations>
					<location>1</location>
					<location>7</location>
					<location>39</location>
				</locations>
			</variant>
			<variant>
				<word>oof</word>
				<locations>
					<location>2</location>
					<location>3</location>
					<location>78</location>
				</locations>
			</variant>
etc.

The second file looks like this:

<locations>
	<location>
		<id>1</id>
		<placename>London</placename>
	</location>
	<location>
		<id>2</id>
		<placename>Tokyo</placename>
	</location>
etc.

I want to do a table in which all the placenames from the second file
are listed, followed by columns for each variant (as many columns as
there are variants) from the first file. So far so good. I want to fill
the columns with cells with the location value from the first file but
only where this number matches the id number from the locations list. If
there's no match, the cell should remain empty. What I have so far (not
working) is:

<xsl:variable name="CurrentVariant" select="../variants/variant"/>
	
<table border="1">
	<tr>
		<td>place</td>
			<xsl:for-each select="../variants/variant">
				<td>
					<xsl:value-of select="word"/>
				</td>
			</xsl:for-each>
		</tr>
		
		<xsl:for-each
select="document('LGWLocations.xml')/locations/location">
			<xsl:sort select="placename"/>
			<tr>
				<td>
					<xsl:value-of
select="placename"/>
				</td>
				<xsl:for-each select="$CurrentVariant">
					<td>
					<xsl:for-each
select="locations/location[. =
document('LGWLocations.xml')/locations/location/id]">
						<xsl:value-of
select="."/>
						</xsl:for-each>
					</td>
				</xsl:for-each>
				
			</tr>
	</xsl:for-each>
</table> 

I can't get the xpath for the last for-each-set right. I know that I
have to somehow match the location with the id from the imported file in
order to get a matrix like this:

placename	foo	oof
London	1	-
Tokyo		-	2
etc.

I'm using MSXML and IE6. Has anyone got any idea how this might be
solved? Much appreciated.
