小编use*_*175的帖子

我想从URL读取XML数据.我有如下网址

http://www.arrowcast.net/fids/mco/fids.asp?sort=city&city=&number=&airline=&adi=A

这是我的代码

$Url="http://www.arrowcast.net/fids/mco/fids.asp?sort=city&city=&number=&airline=&adi=A";  
if (!function_exists('curl_init')){
    die('Sorry cURL is not installed!');
} 
   $ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $Url);   
$output = curl_exec($ch);
$resultCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
// Close the cURL resource, and free system resources
curl_close($ch);

谁能告诉我如何阅读xml数据？

谢谢.....
