фильтровать ответ xml CDATA

Question

Ну, я делаю return simplexml_load_string($data, 'SimpleXMLElement', LIBXML_COMPACT | LIBXML_NOCDATA | LIBXML_NOBLANKS | LIBXML_NOEMPTYTAG ); и разбираю xml-ответ.

Проблема в том, что содержание [description] действительно запутано, и мне нужно выбрать нужные данные.

[description] => 
    <a href="http://www.metacafe.com/watch/cb-YpE1z5IhjWrmCM62DSTU8jQ9X4IZryVR/the_dish_with_doc_willoughby/"><img src="http://s4.mcstatic.com/thumb/8000947/21507982/4/directors_cut/0/1/the_dish_with_doc_willoughby.jpg?v=8" align="right" border="0" alt="THE Dish with Doc Willoughby" vspace="4" hspace="4" width="134" height="78" /></a>

Как вы можете видеть, это действительно испортилось, и мне было интересно, как я могу получить, например, первые <p> данные до "
Ranked ..." и тегов также

Edit:

хорошо, вот код php, который я использую:

        $dom = new DOMDocument();
        @$dom->loadHTML($result->description); // or you can use loadXML
        $dom->normalizeDocument();
        /*$dom->resolveExternals = false;
        $dom->substituteEntities = false;*/
        $xml = simplexml_import_dom($dom);
        $data['viewData']['data']['description'] = $xml;

или

        $paragraph = $dom->getElementsByTagName('p');  -> this doesn't work
        //$xml = simplexml_import_dom($dom);
        $data['viewData']['data']['description'] = $paragraph;

и вот вывод:

                (
                    [body] => SimpleXMLElement Object

Есть ли какой-нибудь способ "сделать выход красивее"? Я имею в виду лучше заказал ... Я также пытался использовать getElementsByTagName('p'), но безуспешно

Answer 1

Взгляните на этот мой предыдущий ответ.Он разбирает строку в объект XML, чтобы вы могли легко получить доступ к любому узлу.

В вашем случае, чтобы получить первый абзац:

<code>$dom = new DOMDocument();
$dom->loadHTML($description); // $description - your string from the feed
if (!$dom) {
    die('Error loading HTML string.');
}

$xml = simplexml_import_dom($dom);
$p = (string)$xml->body->p;

echo '<pre>'; print_r($p); echo '

';
