public function append($string, $path = '//html/body') {
        $xpath = new DOMXPath ( $this->response );
        $elements = $xpath->evaluate ( $path, $this->response );
        foreach ( $elements as $element ) {
            if (! $string instanceof DOMNode) {
                $string_ = $string;
                $string = $this->response->createDocumentFragment ();
                $string->appendXML ( $string_ );
            }
            $element->appendChild ( $this->response->importNode ( $string, true ) );
        }
