tree traversal?

[Robert Brueckmann]

Is there any easy, recursive way to traverse a tree component?  My tree’s data provider is an XML object sent from the db.  I have 3 tree components actually…the 2nd tree is built based on the selection of the 1st tree and the 3rd tree is built based on the selections made in the 1st and 2nd trees.  I want to implement a history manager for this 3-tree navigation and I’m having a hell of a time trying to reset a previously selected node…each node has a unique ID, so I’m saving this id to the state object for my custom history management and then I want to traverse the tree to find the last selected id when the user hits the back button…is there a simple way to just traverse through the tree, find the node with the id that matches the last selected id and then stop traversal?  There’s no set structure to these trees…so I can’t depend on the trees always being the same sizeor to have the same number of branches, sub-branches, sub-sub-branches, etc…which is why I thought recursion would be my best bet but from the API and Flex docs, I can’t find a generic way to traverse the tree…all of their examples show the code explicitly finding a node at specific location and modifying the node…   I hate recursion, it has and will always confuse me to no end so any help with this would be most amazingly appreciated.   Thanks, Rob   Robert L.
