[xsl] sorting on data referenced with document()??

["Carter, Will" <WCarter@xxxxxxxxxxxxxxxx>]

Hi,

I have a sorting problem when I use xsl to combine data from 2 xml files into one html output.

here is my xml file 1 (xml1.xml):
-----------------------
<people>
	<person name="george">
		<cat>cat-zoro</cat>
		<dog>dog-butch</dog>
		<fish>fish-jaws</fish>
	</person>
	<person name="jennifer">
		<cat>cat-felix</cat>
		<dog>dog-fido</dog>
		<fish>fish-moby</fish>
	</person>
	<person name="simon">
		<cat>cat-tom</cat>
		<dog>dog-scooby</dog>
		<fish>fish-conroy</fish>
	</person>
</people>
-----------------------

here is my xml file 2 (xml2.xml):
-----------------------
<people>
	<person name="george">
		<turtle>turtle-greeny</turtle>
	</person>
	<person name="jennifer">
		<turtle>turtle-browny</turtle>
	</person>
	<person name="simon">
		<turtle>turtle-red</turtle>
	</person>
</people>
-----------------------

here is my stylesheet:
-----------------------
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns="http://www.w3.org/tr/REC-html40"; version="2.0">
<xsl:key name="turtleByOwner" match="//turtle" use="../@name" />
<xsl:template match="/">
<table border="1" cellspacing="0" cellpadding="0">
	<xsl:for-each select="people/person">
	<xsl:sort select="cat"/>
	<tr>
		<td colspan="7">Person: <xsl:value-of select="@name"/></td>
	</tr>
	<tr>
		<td><xsl:value-of select="cat"/></td>
		<td><xsl:value-of select="dog"/></td>
		<td><xsl:value-of select="fish"/></td>
		<xsl:variable name="ownerName" select="@name"/>
		<td>
		<xsl:for-each select="document('xml2.xml')">
		<xsl:value-of select="key('turtleByOwner', $ownerName)"
		</xsl:for-each>
		</td>
	</tr>
	</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
-----------------------

this correctly produces (sorted by cat):
-----------------------
Person: jennifer 
cat-felix   dog-fido   fish-moby   turtle-browny 
  
Person: simon 
cat-tom   dog-scooby   fish-conroy   turtle-red 
  
Person: george 
cat-zoro   dog-butch   fish-jaws   turtle-greeny 
-----------------------


but I want to sort by turtle (I want this output):
-----------------------
Person: jennifer 
cat-felix   dog-fido   fish-moby   turtle-browny 

Person: george 
cat-zoro   dog-butch   fish-jaws   turtle-greeny 
 
Person: simon 
cat-tom   dog-scooby   fish-conroy   turtle-red 
-----------------------

I changed the sort line to be:
<xsl:sort select="turtle"/>
but it doesn't work, my output is:
-----------------------
Person: george 
cat-zoro   dog-butch   fish-jaws   turtle-greeny 
  
Person: jennifer 
cat-felix   dog-fido   fish-moby   turtle-browny 
  
Person: simon 
cat-tom   dog-scooby   fish-conroy   turtle-red 
-----------------------

how can I sort on the turtle column from the document reference?

thanks for any ideas.
will
