The Element type is a simple but flexible container object, designed to store hierarchical data structures, such as simplified XML infosets, in memory. The ElementTree package provides a Python implementation of this type, plus code to serialize element trees to and from XML files.

I would like to suggest some additions to Element: walk: A generator that walks a tree in depth-first order. I think this is the same as "getiterator" but the docs are confusing. reverse_walk: Like walk but in the reverse order. walkaround: Walks around the outside of a tree. Each non-terminal node is visited twice. Each node should have a attribute whose values can be NONE, DONE, FIRST, SECOND, and LEAF. kill: Removes a node from a tree. It is replaced by its children. prettyprint: Prints a tree with each node indented according to its depth.
