Schema, Parsers, validators - Other
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntax constraints imposed by XML itself. An XML schema provides a view of the document type at a relatively high level of abstraction.

ElementTree
The Element type is a simple but flexible container object, designed to store hierarchical data structures, such as simplified XML infosets, in memory. The element type can be described as a cross between a Python list and a Python dictionary.
The ElementTree wrapper adds code to load XML files as trees of Element objects, and save them back again.
The Element type is available as a pure-Python implementation for Python 1.5.2 and later. A C implementation is also available, for use with CPython 2.1 and later. The core components of both libraries are also shipped with Python 2.5 and later.
