警告：DOMDocument :: load（）[domdocument.load]：I / O警告：加载外部实体失败

我正在本机使用XAMPP上运行的应用程序中使用这段php脚本：

I was using this piece of php script in a application running under over XAMPP on my local machine:

$dom = new DomDocument();
$filename = "library.xml";

if (!$dom->load($filename))
    die("Could not parse iTunes XML file: ".$filename);

然后，我尝试将此应用程序移动到WampServer而不成功，并显示以下警告：

Then i tried to move this application to a WampServer without success, with the following warning:

Warning: DOMDocument::load() [domdocument.load]: I/O warning : failed to load external entity "file:///C:/wamp/www/parser/library.xml" in C:\wamp\www\parser\includes\libs\itunes_xml_parser.lib.php on line 111

错误中的这一行完全是加载行，它在早期版本的XAMPP中无瑕疵，现在在XAMPP 1.7上不起作用。 7

This line in the error is exactly the load line, which worked flawlessly in earlier versions of XAMPP and isn't working now on XAMPP 1.7.7
