Representing XML in Tree Stores

[dhk <dhkuhl optonline net>]

What is the best way to represent complex xml in a tree store?

It seems like it should be easy, but when looping the models with 
gtk_tree_model_foreach() some problems arise:  especially when there are 
multiple views on different notebook tabs.

The approach I am using is one Tree Store for each complex xml node. 
Then for each item in the first tree I have to loop all other trees to 
find the nodes that belong to it.  I do this by use gtk_tree_model_get() 
on each row to see if the sequence numbers match and if they do it gets 
processed.  The problem I have is I'm looping each store multiple times 
to find what I want, which seems inefficient, instead of looping each 
store once.

Any ideas?

Thanks
