simplexml_import_dom - does not work
<pre>
if (file_exists('http://something_from_a_url.xml')) {
    $xml = simplexml_import_dom('http://something_from_a_url.xml');

    print_r($xml);
} else {
    exit('Failed to open xml file.');
}
</pre>

<p>when I execute this code it says failed to open, I fail to understand why..</p>
