            ElementDepthFirstIterator

ElementDepthFirstIterator(self, node, tag=None, inclusive=True) Iterates over an element and its sub-elements in document order (depth first pre-order).

Note that this also includes comments, entities and processing instructions. To filter them out, check if the `tag` property of the returned element is a string (i.e. not None and not a factory function), or pass the `Element` factory for the `tag` argument to receive only Elements.

If the optional `tag` argument is not None, the iterator returns only the elements that match the respective name and namespace.

The optional boolean argument 'inclusive' defaults to True and can be set to False to exclude the start element itself.

Note that the behaviour of this iterator is completely undefined if the tree it traverses is modified during iteration.
