运行下面的代码后

$xml = simplexml_load_string(utf8_encode($cleaned), 'SimpleXMLElement', LIBXML_NOCDATA);

返回

["item"]=>
array(100) {
  [0]=>
  object(SimpleXMLElement)#4 (5) {
    ["title"]=>
    string(56) "Honda Motor Company: Motorcycles to the Civic and Accord"
    ["link"]=>
    string(42) "http://www.link.com/index.php?id=9987"
    ["description"]=>
    string(232) "long description."
    ["pubDate"]=>
    string(31) "Fri, 23 Sep 2011 10:55:50 -0400"
    ["guid"]=>
    string(74) "https://link.cloudfront.net/581575d3053ac1a578065c10f2bac1be.mp4"
  }

在此之前没有其他代码正在运行，我似乎无法弄清楚为什么地球上发生了这种情况。任何人都知道这背后的原因，是因为utf-8编码？

Answer 1

您需要使用SimpleXMLElement->children()命名空间调用"media"以获取<media:xxx>种格式的部分，或将$ns参数传递给{{1指定要加载的命名空间：

simplexml_load_string()
