XMLList to External XML File

Question

Hi All,
I'm new to Flex, but I've been impressed with it so far. I
was able to create a simple app, where things like navigation trees
and table data were populated based on XML stored inside mx:XMLList
tags inside the main document. In order to clean things up, I
thought I'd move the data into external XML files. I copied the
data out to the files, and verified the data always had a single
top-level node. I then noted that mx:XMLList doesn't support the
'source' attribute, so converted to using mx:XML tags inside the
application mxml. The application now compiles, but entirety of the
XML hierarchy displays as a single node, instead of being parsed
into tree nodes. Any idea what I'm missing here? And thanks in
advance for going easy on the noob. ;-)

Spoke too soon. Looks like that top node thing is right, as
it's only passing in the first node from each xml datasource. It
must've been doing that before, but since the top-node didn't have
a label, it displayed all the children as the label.
So by adding the top-level node to the XML, my guess is that
when I call my data from the dataProvider, I'll have to add
something to bypass this extra layer of hierarchy, right?
Currently my app code has:
<mx:XML id="deviceTree" source="deviceTree.xml" />
<snip/>
<mx:Tree dataProvider="{deviceTree}" />
and my XML (deviceTree.xml) with the new added top node is
now:
<?xml version="1.0" encoding="utf-8"?>
<devices>
<node label="Foo">
<node label="Foo1" />
<node label="Foo2" />
</node>
<node label="Bar">
<node label="Bar1" />
<node label="Bar2" />
</node>
</devices>
I tried changing the dataProvider to {deviceTree.devices} but
to no avail. Can someone throw me a line?
