       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 unfamil‐
       iar with tree-shaped data structures, or with object-oriented modules
       in general. Sean Burke has written some articles for The Perl Journal
       ("") that seek to provide that background.  The full text of
       those articles is contained in this distribution, as:

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

	   "Trees" from TPJ18

	   "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
