我使用 DOMDocument() 来解析 html 并获取 iframe：
$content = '<p>Lorem ip.., </p>
<iframe width="500" height="281" src="http://www.youtube.com/embed/Fv6sHgq6hFc?feature=oembed" frameborder="0" allowfullscreen=""></iframe>
<p>sed diam volup...orem ipsum dolor sit amet.</p>
';
$document = new DOMDocument();
$document->loadHTML( $content );
$lst = $document->getElementsByTagName('iframe');
$videos = array();
for ( $i = 0; $i < $lst->length; $i++ ) {
$iframe = $lst->item($i);
var_dump($iframe);
/* I want to get "<iframe width="500" height="281" src="http://www.youtube.com/embed/Fv6sHgq6hFc?feature=oembed" frameborder="0" allowfullscreen=""></iframe>" here */
}
如何获得像<iframe src="..." attribute 1>或<iframe src="..." attribute 1></iframe>一样的整个 iframe？
谢谢！
尝试：
foreach($lst as $iframe) {
var_dump($document->saveHtml($iframe));
}
仅适用于 PHP>= 5.3.6
否则：
foreach($lst as $iframe) {
$cloned = $iframe->cloneNode(TRUE);
$newdoc = new DOMDocument();
$newdoc->appendChild($newdoc->importNode($cloned,TRUE));
var_dump($newdoc->saveHTML());
}
