    NAME

    HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder
     
    

    SYNOPSIS

      See the documentation for HTML::TreeBuilder
    
    
     

    DESCRIPTION

    Disclaimer: This module is provided only for backwards compatibility with earlier versions of this library. New code should not use this module, and should really use the HTML::Parser and HTML::TreeBuilder modules directly, instead.

    The "HTML::Parse" module provides functions to parse HTML documents. There are two functions exported by this module:

    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 "HTML::Parser". Refer to HTML::Parser for more documentation.

    If $obj is not specified, the $obj will default to an internally created new "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.

    parse_htmlfile($file, [$obj])
    Same as parse_html(), but pulls the HTML to parse, from the named file.

    Returns "undef" if the file could not be opened, or $obj otherwise.

    When a "HTML::TreeBuilder" object is created, the following variables control how parsing takes place:

    $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.

    $HTML::Parse::IGNORE_UNKNOWN
    This variable contols whether unknow tags should be represented as elements in the parse tree. Default is true.
    $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.
    $HTML::Parse::WARN
    Call warn() with an apropriate message for syntax errors. Default is false.
     

    REMEMBER!

    HTML::TreeBuilder objects should be explicitly destroyed when you're finished with them. See HTML::TreeBuilder.
