title: PHPExcel factory error when reading XML from URL
body: <p>How to create XML reader from the URL XML data?
  I provide valid XML data from a URL to the <code>PHPExcel</code> factory's <code>identify()</code> but the script fires an error:</p>
  
  <blockquote>
    <p>( ! ) Fatal error: Uncaught exception 'PHPExcel_Reader_Exception' with
    message ' in C:\wamp\www\project\Classes\PHPExcel\Reader\Excel2007.php
    on line 82 </p>
    
    <p>( ! ) PHPExcel_Reader_Exception: Could not open for
    reading! File does not exist. in
    C:\wamp\www\project\Classes\PHPExcel\Reader\Excel2007.php on line 82</p>
  </blockquote>
  
  <pre><code>$url = "http://www.w3schools.com/xml/note.xml";
  $xml = simplexml_load_file($url); //OR $xml = simplexml_load_string(file_get_contents($url));
  $inputFileType = PHPExcel_IOFactory::identify($xml); // ERROR
  </code></pre>
  
  <p><strong>UPDATE:</strong></p>
  
  <pre><code>$dom = new DOMDocument();
  $dom-&gt;load($url);
  $fileName = 'filename.xml';
  $xml = $dom-&gt;save($fileName);
  $inputFileType = PHPExcel_IOFactory::identify($xml);
  </code></pre>
