## NAME
    [XML::SAX::PurePerl](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ASAX%3A%3APurePerl/markdown) - Pure Perl XML Parser with SAX2 interface

## SYNOPSIS
      use [XML::Handler::Foo](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3AHandler%3A%3AFoo/markdown);
      use [XML::SAX::PurePerl](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ASAX%3A%3APurePerl/markdown);
      my $handler = [XML::Handler::Foo](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3AHandler%3A%3AFoo/markdown)->new();
      my $parser = [XML::SAX::PurePerl](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ASAX%3A%3APurePerl/markdown)->new(Handler => $handler);
      $parser->parse_uri("myfile.xml");

## DESCRIPTION
    This module implements an XML parser in pure perl. It is written around the upcoming perl 5.8's
    unicode support and support for multiple document encodings (using the PerlIO layer), however it
    has been ported to work with ASCII/UTF8 documents under lower perl versions.

    The SAX2 API is described in detail at <http://sourceforge.net/projects/perl-xml/>, in the CVS
    archive, under libxml-perl/docs. Hopefully those documents will be in a better location soon.

    Please refer to the SAX2 documentation for how to use this module - it is merely a front end to
    SAX2, and implements nothing that is not in that spec (or at least tries not to - please email
    me if you find errors in this implementation).

## BUGS
    [XML::SAX::PurePerl](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ASAX%3A%3APurePerl/markdown) is slow. Very slow. I suggest you use something else in fact. However it is
    great as a fallback parser for [XML::SAX](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ASAX/markdown), where the user might not be able to install an XS based
    parser or C library.

    Currently lots, probably. At the moment the weakest area is parsing DOCTYPE declarations, though
    the code is in place to start doing this. Also parsing parameter entity references is causing me
    much confusion, since it's not exactly what I would call trivial, or well documented in the XML
    grammar. XML documents with internal subsets are likely to fail.

    I am however trying to work towards full conformance using the Oasis test suite.
