have you tried including simple-html-dom.php like this
require_once('simple_html_dom.php');

This project doesn't support Composer, so the autoloader feature doesn't work. @json-born is right, you should require the parser in order to use it in your project. Alternatively you can add the parser manually to your autoloader script: https://getcomposer.org/doc/01-basic-usage.md#autoloading
