Need help trying to Navigate tree

Question

Hi there,
Im a flex novice and im not sure if this is the right place
for this post but i couldnt find anywhere else so apologies in
advance.
Im trying to make a flex application which takes in
information from an xml file, plugs it into a navigation tree then,
when the appropriate node is selected displays some rich text in a
central panel. I have this working but i would also like to be able
to navigate through the parent nodes of the tree. This is where i
am encountering a problem. I dont really know how to load in my xml
in order to manipulate it like i want. Should it be in a XMLListm,
a XMLListCollection or something else?
I have two buttons at the bottom of my tree panel, one for
previous and one for next and i want to be able to navigate through
the slides. So if i am on one parent node i want to press next then
go to the next parent node, open it and display the first child of
it. If i am on a child node i want to press next and go to the next
parent, open it and display the first child of it.
I have spent ages trying to solve this problem and im really
sorry if this is the wrong forum but im desperate. I've looked all
over the web, used all my training resources and i just cant get
it.
Here is the code, at this point in time im just loading in an
image and some text.
Any help would be greatly appreciated,
Thanks so much.

If you are restoring from an icloud backup you are going to have to erase a content and setting and while in the setup prompts you will get the option to restore from an icloud back...that's the only time you will get the option to restore from an icloud back and that's during setup
