Introduction to PyXML Module

The PyXML package contains a validating XML parser, an implementation of the SAX and DOM programming interfaces, an interface to the Expat parser, and a C helper module that can speed up xmllib.py by a factor of five. This is useful for validating, parsing and manipulating XML files using Python programs.

This package is known to build and work properly using an LFS-7.1 platform.
