Description:

XML_HTMLSax3 is a SAX based XML parser for badly formed XML documents,
such as HTML. The original code base was developed by Alexander Zhukov
and published at http://sourceforge.net/projects/phpshelve/. Alexander
kindly gave permission to modify the code and license for inclusion in
PEAR.

PEAR::XML_HTMLSax3 provides an API very similar to the native PHP XML
extension (http://www.php.net/xml), allowing handlers using one to be
easily adapted to the other. The key difference is HTMLSax will not
break on badly formed XML, allowing it to be used for parsing HTML
documents. Otherwise HTMLSax supports all the handlers available from
Expat except namespace and external entity handlers. Provides methods
for handling XML escapes as well as JSP/ASP opening and close tags.

Version 1.x introduced an API similar to the native SAX extension but
used a slow character by character approach to parsing.

Version 2.x has had it's internals completely overhauled to use a
Lexer, delivering performance *approaching* that of the native XML
extension, as well as a radically improved, modular design that makes
adding further functionality easy.

Version 3.x is about fine tuning the API, behaviour and providing a
mechanism to distinguish HTML "quirks" from badly formed HTML (later
functionality not yet implemented)

A big thanks to Jeff Moore (lead developer of WACT:
http://wact.sourceforge.net/) who's largely responsible for new
design, as well input from other members at Sitepoint's Advanced PHP
forums: http://www.sitepointforums.com/showthread.php?threadid=121246.

Thanks also to Marcus Baker (lead developer of SimpleTest:
http://www.lastcraft.com/simple_test.php) for sorting out the unit
tests.

In PEAR status of this package is: beta.
