HTML::Tree(3)                        User Contributed Perl Documentation                       HTML::Tree(3)



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

VERSION
       4.2

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 objectoriented
       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.
