好吧，我做了一个return simplexml_load_string($data, 'SimpleXMLElement', LIBXML_COMPACT | LIBXML_NOCDATA | LIBXML_NOBLANKS | LIBXML_NOEMPTYTAG );并解析xml响应。
问题是[描述]的内容真的很混乱，我需要选择我需要的数据。

正如你所看到的，它真的很糟糕，我想知道如何才能获得第一个<p>的数据，例如，直到"
排名…"和标签也是
编辑：
好的，这是我正在使用的php代码：
$dom = new DOMDocument();
@$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;
或
$paragraph = $dom->getElementsByTagName('p'); -> this doesn't work
//$xml = simplexml_import_dom($dom);
$data['viewData']['data']['description'] = $paragraph;
这是输出：
[description] => SimpleXMLElement Object
(
[body] => SimpleXMLElement Object
(
[a] => SimpleXMLElement Object
(

有没有什么方法可以"让输出更漂亮"？我的意思是秩序更好。。。我也尝试过使用getElementsByTagName('p')，但没有成功
看看我之前的回答。它将字符串解析为XML对象，这样您就可以轻松地访问任何节点。
在你的情况下得到第一段：
$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 '</pre>';
