The path of the PHP file has nothing to do with it's namespace in code.

simple_html_dom resides in the root namespace, so register the proper file path, then instantiate with the proper namespace.

// simple_httml_dom has only one source php file, register it as a file
$loader->registerFiles([
    $config->application->libraryDir . "simplehtmldom/simple_html_dom.php",
]);
// Instantiate from root namespace
$dom = new \simple_html_dom();
