    </body></html>
    Outside HTML
    HTML;

    $tidy = tidy_parse_string($html);
    $num = 0;

    get_nodes($tidy->html());

    function get_nodes($node) {

        // check if the current node is of requested type
        if($node->isJste()) {
            echo "\n\n# jste node #" . ++$GLOBALS['num'] . "\n";
            echo $node->value;
        }

        // check if the current node has children
        if($node->hasChildren()) {
            foreach($node->child as $child) {
                get_nodes($child);
            }
        }
    }

The above example will output:

    # jste node #1
    <#
