NAME

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

CONTENTS

VERSION

This document describes version 5.03 of HTML::Parse, released September 22, 2012 as part of HTML-Tree.

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 appropriate message for syntax errors. Default is false.

REMEMBER!

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