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


  See the documentation for HTML::TreeBuilder



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:

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.

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


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