【问题描述】：
由于某种原因，我用来将 feedburner 计数为在我的网站 (http://ios-blog.co.uk) 周围使用的字符串的脚本已停止工作 :( 这是它抛出的错误：
Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: Entity: line 2: parser error : Opening and ending tag mismatch: meta line 1 and HEAD in /home/connect.php on line 83
Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: <TITLE>301 Moved</TITLE></HEAD><BODY> in /home/connect.php on line 83

Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /home/connect.php:83 Stack trace: #0 /home/connect.php(83): SimpleXMLElement->__construct('<HTML><HEAD><me...') #1 {main} thrown in /home/connect.php on line 83
这是我正在使用的 PHP：
//get cool feedburner count
$whaturl="http://api.feedburner.com/awareness/1.0/GetFeedData?uri=iosdevblog";
//Initialize the Curl session
$ch = curl_init();
//Set curl to return the data instead of printing it to the browser.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//Set the URL
curl_setopt($ch, CURLOPT_URL, $whaturl);
//Execute the fetch
$data = curl_exec($ch);
//Close the connection
curl_close($ch);
$xml = new SimpleXMLElement($data);
$fb = $xml->feed->entry['circulation'];
echo $fb;
//end get cool feedburner count
文件很大 - 上面写着 83 与它相关的行：$xml = new SimpleXMLElement($data);
感谢大家的帮助:)
