title: UPS tracking request doesn't return number of packages within shipment if there is more than one
body: <p>I've got different shipments and some of them contain more then one package. I've created this request:</p>
  
  <pre><code>$data ="&lt;?xml version=\"1.0\"?&gt;
  &lt;AccessRequest xml:lang='en-US'&gt;
          &lt;AccessLicenseNumber&gt;myLicenceNumber&lt;/AccessLicenseNumber&gt;
          &lt;UserId&gt;myUserId&lt;/UserId&gt;
          &lt;Password&gt;myPass&lt;/Password&gt;
  &lt;/AccessRequest&gt;
  &lt;?xml version=\"1.0\"?&gt;
  &lt;TrackRequest&gt;
          &lt;Request&gt;
                  &lt;TransactionReference&gt;
                          &lt;CustomerContext&gt;
                                  &lt;InternalKey&gt;hello&lt;/InternalKey&gt;
                          &lt;/CustomerContext&gt;
                          &lt;XpciVersion&gt;1.0&lt;/XpciVersion&gt;
                  &lt;/TransactionReference&gt;
                  &lt;RequestAction&gt;Track&lt;/RequestAction&gt;
          &lt;/Request&gt;
  &lt;TrackingNumber&gt;myTrackingNumber&lt;/TrackingNumber&gt;
  &lt;/TrackRequest&gt;";
  $ch = curl_init("https://www.ups.com/ups.app/xml/Track");
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch,CURLOPT_POST,1);
  curl_setopt($ch,CURLOPT_TIMEOUT, 60);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
  curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
  curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
  $result=curl_exec ($ch);
  $data = strstr($result, '&lt;?');
  $xml=simplexml_load_string($data);
  print_r($xml);

  <p>It returns a lot of valuable information, but it doesn't return number of packages if there is more than one. How can I get this information, which is called "Multiple Packages"? Thank you.</p>
