[jdom-interest] breadth first traversal, nextElement()

From your previous posts I inferred that 11 would be last because it is the deepest child of the last branch.  But my comprehension of your problem was incorrect.  Usually, if I was to parse an entire tree manually I would complete each branch iteratively before beginning on the next.  For example, I would hit 1,2,5,12 before starting on 3,6,7,13,14,8.

That's pretty much the difference between a depth first traversal 
(in-order) and a breadth-first traversal.
My project relies on breadth-first traversal.. so it's easier to do 
that.. than alter everything else.. I think :)
I'm sure that there was a good reason for everything working out this 
way... there must be

Of all God's creatures there is only one that cannot be made the slave 
of the lash. That one is the cat. If man could be crossed with a cat it 
would improve man, but it would deteriorate the cat.
