S ) z#getETreeBuilder.<locals>.TreeWalkera� Given the particular ElementTree representation, this implementation,
to avoid using recursion, returns "nodes" as tuples with the following
content:
1. The current element
2. The index of the element relative to its parent
3. A stack of ancestor elements
4. A flag "text", "tail" or None to indicate if the current node is a
text node; either the text or tail of the current element (1)
