=head1 NAME

HTML::Tree - build and scan parse-trees of HTML

=head1 VERSION

This document describes version 5.07 of
HTML::Tree, released August 31, 2017
as part of L<HTML-Tree|HTML::Tree>.

=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

        # Finally:

    $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. Sean Burke has written some articles for
I<The Perl Journal> (C<www.tpj.com>) that seek to provide that background.
The full text of those articles is contained in this distribution, as:

=over 4

=item L<HTML::Tree::AboutObjects|HTML::Tree::AboutObjects>

"User's View of Object-Oriented Modules" from TPJ17.

=item L<HTML::Tree::AboutTrees|HTML::Tree::AboutTrees>

"Trees" from TPJ18

=item L<HTML::Tree::Scanning|HTML::Tree::Scanning>

"Scanning HTML" from TPJ19

=back

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.

=head1 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.

=head2 new

Redirects to L<HTML::TreeBuilder/new>.

=head2 new_from_file

Redirects to L<HTML::TreeBuilder/new_from_file>.

=head2 new_from_content

Redirects to L<HTML::TreeBuilder/new_from_content>.

=head2 new_from_url

Redirects to L<HTML::TreeBuilder/new_from_url>.
