Fredrik Lundh wrote Element Tree, so he'd know the best solution, but
I'd like to point out that this is also trivially easy with recursion:


def print_nodes(element, ancestors = []):
    s = hierarchy = ancestors + ["<" + element.tag + ">"]
    if element.text is not None:
        s = s + [element.text]
    print " ".join(s)
    for subelement in element:
        print_nodes(subelement,hierarchy)
