I'm not so sure about that; I think that's a real design error there.
Because an object can only have return one iterator, something like an
element has to decide if it will be iterable over its child nodes,
elements, attributes or namespaces.

I make my iterators implement iterable instead:
public Iterator<Node> iterator() {
       return this;
   }

This lets you

for(Element e:root.elementIterator() ) { ... }
and
for(Attribute e:root.attributeIterator() ) { ... }

This will probably be considered an abuse of the interface come the
next edition of Effective Java, but, well, tough.
