Build and Scan Parse-Trees of Html

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 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.
