-
- HTML::Tree - overview of HTML::TreeBuilder et al
-
- =head1 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
- #
- # Then:
- $tree->delete;
-
- =head1 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: L<HTML::TreeBuilder|HTML::TreeBuilder>
- and L<HTML::Element|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. I have written some articles for I<The Perl
- Journal> (C<www.tpj.com>) that seek to provide that background:
- my article "A User's View of Object-Oriented Modules" in TPJ17;
- my article "Trees" in TPJ18;
- and
- my article "Scanning HTML" in TPJ19.
- The full text of those articles is contained in this distribution, as:
-
- L<HTML::Tree::AboutObjects|HTML::Tree::AboutObjects>
- -- article: "User's View of Object-Oriented Modules"
-
- L<HTML::Tree::AboutTrees|HTML::Tree::AboutTrees>
- -- article: "Trees"
-
- L<HTML::Tree::Scanning|HTML::Tree::Scanning>
- -- article: "Scanning HTML"
-
- 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.
