[xsl] Passing in a node value

[Gregory Propf <gpropf@xxxxxxxxxx>]

I am trying to create an XML-XSL based menu system for a website.  I 
want to be able to designate some menu items as "expanded" and others as 
not.  The idea is that a user clicks a menu link and the frame reloads 
with that menu node expanded to show the subitems.  I have XML that 
looks like this.

<?xml version="1.0" encoding="UTF-8"?>
<Menuitem Name="Root_item" expanded="false">
  <Menuitem Name="sub_item1" expanded="false">subitem1</Menuitem>
  <Menuitem Name="sub_item2" expanded="false">subitem2</Menuitem>
  <Menuitem Name="sub_item3" expanded="false">subitem3</Menuitem>
  <Menuitem Name="sub_item4" expanded="false">subitem4
    <Menuitem Name="sub_sub_item1" 
expanded="false">sub_sub_item1</Menuitem>
    <Menuitem Name="sub_sub_item2" 
expanded="false">sub_sub_item2</Menuitem>
    <Menuitem Name="sub_sub_item3" 
expanded="false">sub_sub_item3</Menuitem>
  </Menuitem>
</Menuitem>

The idea is that I want to set the expanded values to true dynamically 
as people hit the site and want to see the subnodes.  I'll probably be 
using Xalan called from a servlet (Java).  I initially thought I could 
just create a hash with node names as keys.  Apparently XSL doesn't 
support hashes though.  Anyone know how to do this or something that 
will be equivalent.  Also Can anyone recommend a good xsl-xpath 
reference, preferable free and online.
