我的RSS阅读脚本在本地主机上工作正常但在[000webhost]它不起作用，我仔细检查了rss url和脚本，因为任何bug尝试了不同的RSS网址但注意到了作品

它在000webhost生成以下错误

Warning: DOMDocument::load() [domdocument.load]: Document is empty in http://www.voanews.com/api/epiqq, line: 1 in /home/a999999/public_html/index.php on line 190

我的脚本在

下面

$xml=("http://www.voanews.com/api/epiqq");

$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);

//get elements from "<channel>"

$channel=$xmlDoc->getElementsByTagName('channel')->item(0);
$channel_title = $channel->getElementsByTagName('title')
->item(0)->childNodes->item(0)->nodeValue;
$channel_link = $channel->getElementsByTagName('link')
->item(0)->childNodes->item(0)->nodeValue;
$channel_desc = $channel->getElementsByTagName('description')
->item(0)->childNodes->item(0)->nodeValue;


//get and output "<item>" elements
$x=$xmlDoc->getElementsByTagName('item');
for ($i=0; $i<$x->length; $i++) {



 $irss[] = array(
    'title' => $x->item($i)->getElementsByTagName('title')
  ->item(0)->childNodes->item(0)->nodeValue,
    'link' => $x->item($i)->getElementsByTagName('link')
  ->item(0)->childNodes->item(0)->nodeValue,

  ->item(0)->childNodes->item(0)->nodeValue,

  ->item(0)->childNodes->item(0)->nodeValue

  );
