Restore Treeview From FullPath

I've got a dataset that I maintain. The user interface to the dataset is a treeview and a listbox. The listbox shows the "items" in the treeview node that is currently selected. This works fantastic. As items are added to the dataset, I grab the fullpath property of the treeview node so I can filter and only display items that belong to the in the node that is selected. I then save all of this information to an XML file (including the fullpath of the node that the item is "in").

This all works great and does everything that I want it to. The problem comes when I load the XML file back in. I'm trying to re-create the treeview nodes exactly as they were when the document was saved. I know what the nodes are because of the fullpath property, it looks something like this: State\City\SiteName

I'm trying to create a sub (or function) to recursively create this structure. I've managed to get close, but I haven't actually got the logic yet. I've been able to get all the nodes added, but they seem to only be added at the second level. One thing that I need to worry about is duplicates. In the example above, I might have two sites in the same City. When I got close, I actually had the structure created, but the nodes were getting duplicated. For example: [Code]
