use HTML::TreeBuilder; my $tree = HTML::TreeBuilder->new(); $tree->parse_file($filename);
# Then do something with the tree, using HTML::Element # methods -- for example:
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:
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.
