NAME

my $tree = HTML::TreeBuilder->new();

 # methods -- for example $tree->dump
 #
 # Then:
$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 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. I have written some articles for The Perl Journal (www.tpj.com) that seek to provide that background: my article "Scanning HTML" in TPJ19; my article "Trees" in TPJ18, and my article "A User's View of Object-Oriented Modules" in TPJ17. The full text of those articles will likely appear in a later version of this HTML-Tree module distribution.
