Nested XML Tree View

Hi,
I have the following XML:

<?xml version="1.0"?>
<VARIABLEGROUPS>
	<VARIABLEGROUP>
		<NAME>MyGroup</NAME>
		<TABLE>
			<NAME>Plate</NAME>
			<VARIABLE>
				<NAME>Max_Response</NAME>
			</VARIABLE>
			<TABLE>
				<NAME>Well</NAME>
				<VARIABLE>
					<NAME>Well_ID</NAME>
				</VARIABLE>
			</TABLE>
		</TABLE>
	</VARIABLEGROUP>
</VARIABLEGROUPS>

Group: MyGroup
	Table: Plate
		Variable: Max_Response
		Table: Well
			Variable: Well_ID
