package HTML::Parse; =head1 NAME HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder =head1 SYNOPSIS See the documentation for HTML::TreeBuilder =head1 DESCRIPTION Disclaimer: This module is provided only for backwards compatibility with earlier versions of this library. New code should I<not> use this module, and should really use the HTML::Parser and HTML::TreeBuilder modules directly, instead. The C<HTML::Parse> module provides functions to parse HTML documents. There are two functions exported by this module: =over 4 =item parse_html($html) or parse_html($html, $obj) This function is really just a synonym for $obj->parse($html) and $obj is assumed to be a subclass of C<HTML::Parser>. Refer to L<HTML::Parser> for more documentation. If $obj is not specified, the $obj will default to an internally created new C<HTML::TreeBuilder> object configured with strict_comment() turned on. That class implements a parser that builds (and is) a HTML syntax tree with HTML::Element objects as nodes. The return value from parse_html() is $obj. =item parse_htmlfile($file, [$obj]) Same as parse_html(), but pulls the HTML to parse, from the named file. Returns C<undef> if the file could not be opened, or $obj otherwise. =back When a C<HTML::TreeBuilder> object is created, the following variables control how parsing takes place: =over 4 =item $HTML::Parse::IMPLICIT_TAGS Setting this variable to true will instruct the parser to try to deduce implicit elements and implicit end tags. If this variable is false you get a parse tree that just reflects the text as it stands. Might be useful for quick & dirty parsing. Default is true. Implicit elements have the implicit() attribute set. =item $HTML::Parse::IGNORE_UNKNOWN This variable contols whether unknow tags should be represented as elements in the parse tree. Default is true. =item $HTML::Parse::IGNORE_TEXT Do not represent the text content of elements. This saves space if all you want is to examine the structure of the document. Default is false. =item $HTML::Parse::WARN Call warn() with an apropriate message for syntax errors. Default is false. =back =head1 REMEMBER! HTML::TreeBuilder objects should be explicitly destroyed when you're finished with them.
