SYNOPSIS

12           use HTML::TreeBuilder;
13           my $tree = HTML::TreeBuilder->new();
14           $tree->parse_file($filename);
15
16               # Then do something with the tree, using HTML::Element
17               # methods -- for example:
18
19           $tree->dump
20
21               # Finally:
22
23           $tree->delete;

DESCRIPTION

26       HTML-Tree is a suite of Perl modules for making parse trees out of HTML
27       source.  It consists of mainly two modules, whose documentation you
28       should refer to: HTML::TreeBuilder and HTML::Element.
29
30       HTML::TreeBuilder is the module that builds the parse trees.  (It uses
31       HTML::Parser to do the work of breaking the HTML up into tokens.)
32
33       The tree that TreeBuilder builds for you is made up of objects of the
34       class HTML::Element.
35
36       If you find that you do not properly understand the documentation for
37       HTML::TreeBuilder and HTML::Element, it may be because you are unfamil‐
38       iar with tree-shaped data structures, or with object-oriented modules
39       in general. Sean Burke has written some articles for The Perl Journal
40       ("www.tpj.com") that seek to provide that background.  The full text of
41       those articles is contained in this distribution, as:
42
43       HTML::Tree::AboutObjects
44           "User's View of Object-Oriented Modules" from TPJ17.
45
46       HTML::Tree::AboutTrees
47           "Trees" from TPJ18
48
49       HTML::Tree::Scanning
50           "Scanning HTML" from TPJ19
51
52       Readers already familiar with object-oriented modules and tree-shaped
53       data structures should read just the last article.  Readers without
54       that background should read the first, then the second, and then the
55       third.
