Treeview from XML As Options Menu

I am looking at saving user and application settings in an XML file (Which I can do currently with hardcoded values).
What I am after is an idea for an Options Window to display ALL settings using a Treeview.
For Instance - I want a Treeview with the nodes displayed for each settings area like this

Global
    Global Database
    Global Titles
User
    User Settings

I then want a window to the right with the Attribute settings
So for Global Database the right window would show

Server : XXXXXXX with the XXXX as user input Value
Database : XXXXXXXX with the XXXX as user input Value
Authentication : Trusted  as a combo box.

Is it possible using HierarchicalDataTemplate to just list the nodes on the left and then attributes on the right.
