title: JQuery request XML from FTP
body: <p>Can I use JQuery to download a XML file on a FTP server?
  I want to parse the file size from the XML. Use 2754 as example value.</p>
  
  <pre><code>function getPDBEFileSizeByID(pdbeID) {
      pdbeID = '2754';
      var url = "ftp://ftp.ebi.ac.uk/pub/databases/emdb/structures/EMD-" + pdbeID + "/header/emd-" + pdbeID + ".xml";
  
      var request = $.get(url);
  
      request.done(function(response) {
          var xmlDoc = $.parseXML(response);
  
          $fileSpecs = $(xmlDoc).find('*/map/file');
          var sizeKB = $fileSpecs.attr('sizeKb');
  
      });
  }
  </code></pre>
  
  <p>Right now I am getting a CORS error. I know what it is of course, but not sure if that's an effect of JQuery or FTP.</p>
  
  <p>EDIT:
  CORS is only available for HTTP, ok. I must integrate that on the serverside then...</p>
