Wendell,

Thanks for your help.  The code works - sort of.

If the <id> corresponds to the first person in the ShareWebUsers.xml, it returns the correct value of the <ntname> tag.  If the <id> is for the 2nd ... nth person, I get nothing.

There is a sample of what ShareWebUsers.xml looks like:

<?xml version="1.0" encoding="UTF-8"?>
<directory>
	<person>
		<id>4763453</id>
		<ntname>zvolenst</ntname>
	</person>
	<person>
		<id>1580652</id>
		<ntname>watsonc</ntname>
	</person>
	<person>
		<id>3113434</id>
		<ntname>zabkas</ntname>
	</person>
</directory>

Any idea why I can't get the ntname back for 1580652 or 3113434?

Hello Thomas,

No.

This is how I would do it:

Outside your template, bind the other document to a variable:

<xsl:variable name="lookupdoc" select="document('ShareWebUsers.xml')"/>

Set up a key to retrieve persons by id element child:

<xsl:key name="personsbyID" match="person" use="id"/>

(In your code, you have "person[id=..." so I've said use="id"; change to 
@id if you're actually wanting an attribute not an element)

Then inside your template:

<xsl:for-each select="//*[./@filename != '']">
   <xsl:variable name="ownedby" select="../@ownedby"/>
   <!-- binds the ownedby to a variable so we can get it after
        we change context -->
   <xsl:for-each select="$lookupdoc">
     <!-- change context to lookup doc -->
     <xsl:value-of select="key('personsbyID',$ownedby)/ntname"/>
   </xsl:for-each>
</xsl:for-each>

If you wanted to skip the whole key thing you could simply do

<xsl:value-of 
select="document('ShareWebUsers.xml')//person[id=$ownedby]"/>]/ntname"/>

but that's relatively more expensive (since ShareWebUsers.xml will have to 
be traversed again and again, and maybe even parsed repeatedly depending on 
your processor).

<xsl:value-of select="$lookupdoc//person[id=$ownedby]"/>]/ntname"/>

may be somewhat better but is still costly compared to using the key.

HTH--
