HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder 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. SEE ALSO

HTML::Tree - build and scan parse-trees of HTML VERSION
This document describes version 5.03 of HTML::Tree, released September 22, 2012 as part of HTML-Tree. SYNOPSIS
use HTML::TreeBuilder; my $tree = HTML::TreeBuilder->new(); $tree->parse_file($filename); # Then do something with the tree, using HTML::Element # methods -- for example: $tree->dump # Finally: $tree->delete; DESCRIPTION
HTML-Tree is a suite of Perl modules for making parse trees out of HTML source. It consists of mainly two modules, whose documentation you should refer to: HTML::TreeBuilder and HTML::Element. HTML::TreeBuilder is the module that builds the parse trees. (It uses HTML::Parser to do the work of breaking the HTML up into tokens.) The tree that TreeBuilder builds for you is made up of objects of the class HTML::Element. If you find that you do not properly understand the documentation for HTML::TreeBuilder and HTML::Element, it may be because you are unfamiliar with tree-shaped data structures, or with object-oriented modules in general. Sean Burke has written some articles for The Perl Journal ("www.tpj.com") that seek to provide that background. The full text of those articles is contained in this distribution, as: HTML::Tree::AboutObjects "User's View of Object-Oriented Modules" from TPJ17. HTML::Tree::AboutTrees "Trees" from TPJ18 HTML::Tree::Scanning "Scanning HTML" from TPJ19 Readers already familiar with object-oriented modules and tree-shaped data structures should read just the last article. Readers without that background should read the first, then the second, and then the third. METHODS
All these methods simply redirect to the corresponding method in HTML::TreeBuilder. It's more efficient to use HTML::TreeBuilder directly, and skip loading HTML::Tree at all. new Redirects to "new" in HTML::TreeBuilder. new_from_file Redirects to "new_from_file" in HTML::TreeBuilder. new_from_content Redirects to "new_from_content" in HTML::TreeBuilder. new_from_url Redirects to "new_from_url" in HTML::TreeBuilder. SUPPORT
You can find documentation for this module with the perldoc command. perldoc HTML::Tree You can also look for information at: o AnnoCPAN: Annotated CPAN documentation <http://annocpan.org/dist/HTML-Tree> o CPAN Ratings <http://cpanratings.perl.org/d/HTML-Tree> o RT: CPAN's request tracker <http://rt.cpan.org/NoAuth/Bugs.html?Dist=HTML-Tree> o Search CPAN <http://search.cpan.org/dist/HTML-Tree> o Stack Overflow <http://stackoverflow.com/questions/tagged/html-tree> If you have a question about how to use HTML-Tree, Stack Overflow is the place to ask it. Make sure you tag it both "perl" and "html-tree". SEE ALSO
