E4x is great for returning XMLLists but you are really asking form a transformation, right? You want the same structure, but without the <node>s where type="file", correct?
Maybe someone else will have a better idea, but if I needed this I would just write a recursive function to walk the original and build the transformed structure.

That turns out to be rather difficult because <node/> elements are nested.
