In this second article of the series I'm going to discuss how to extract different sections of a specific (X)HTML document (called file nodes) by using the capabilities provided by some additional functions included with this library.

They start by pulling the document into a Tidy instance and formating it a bit before moving on. Following this, they work with a few of the methods Tidy has to offer to pull information from the parsed document - tidy_get_html, tidy_get_head, tidy_get_body and tidy_get_output.
