SAX Utilities
=============

Convenience functions and classes for use with SAX.

_Added in Python version 2.0_

The module `xml.sax.saxutils' contains a number of classes and
functions that are commonly useful when creating SAX applications,
either in direct use, or as base classes.

`escape(data[, entities])'
     Escape &, <, and > in a string of data.

     You can escape other strings of data by passing a dictionary as the
     optional entities parameter.  The keys and values must all be
     strings; each key will be replaced with its corresponding value.

`XMLGenerator([out[, encoding]])'
     This class implements the `ContentHandler' interface by writing
     SAX events back into an XML document. In other words, using an
     `XMLGenerator' as the content handler will reproduce the original
     document being parsed. OUT should be a file-like object which will
     default to SYS.STDOUT. ENCODING is the encoding of the output
     stream which defaults to `'iso-8859-1''.

`XMLFilterBase(base)'
     This class is designed to sit between an `XMLReader' and the
     client application's event handlers.  By default, it does nothing
     but pass requests up to the reader and events on to the handlers
     unmodified, but subclasses can override specific methods to modify
     the event stream or the configuration requests as they pass
     through.

`prepare_input_source(source[, base])'
     This function takes an input source and an optional base URL and
     returns a fully resolved `InputSource' object ready for reading.
     The input source can be given as a string, a file-like object, or
     an `InputSource' object; parsers will use this function to
     implement the polymorphic SOURCE argument to their `parse()'
     method.
