Class CSSContentParser

CSSContentParser enables parsing & assertion running of HTML content via CSS selectors.

It works by converting the content to XHTML using tidy, rewriting the CSS selectors as XPath queries, and executing those using SimpeXML.

It was built to facilitate testing using PHPUnit and contains a number of assert methods that will throw PHPUnit assertion exception when applicable.

Tries to use the PHP Tidy extension (http://php.net/tidy), and falls back to the "tidy" CLI tool. If none of those exists, the string is parsed directly without sanitization.
