Hi
I have one application which have xml like this:

<?xml version="1.0" encoding="utf-8" ?>
<XML xmlns="http://www.abc.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="xxxx.xsd">
<Device make="P" model="V">
<!--Group Information-->
<Groups>
<Group name="h">
<Device>P_V4</Device>
<Device>P_n</Device>
</Group>
....
....
</Device>
</XML>


How can I access the elements under the tag "Group"??

suggest me some good tutorial regarding the namesapaces and xpath queries?
