1	n/a	"""Simple API for XML (SAX) implementation for Python.
2	n/a
3	n/a	This module provides an implementation of the SAX 2 interface;
4	n/a	information about the Java version of the interface can be found at
5	n/a	http://www.megginson.com/SAX/. The Python version of the interface is
6	n/a	documented at <...>.
7	n/a
8	n/a	This package contains the following modules:
9	n/a
10	n/a	handler -- Base classes and constants which define the SAX 2 API for
11	n/a	the 'client-side' of SAX for Python.
12	n/a
13	n/a	saxutils -- Implementation of the convenience classes commonly used to
14	n/a	work with SAX.
15	n/a
16	n/a	xmlreader -- Base classes and constants which define the SAX 2 API for
17	n/a	the parsers used with SAX for Python.
18	n/a
19	n/a	expatreader -- Driver that allows use of the Expat parser with SAX.
