title: Zend_Soap_Client gets "looks like we got no XML document" error
body: <p>I am trying to access a Web Service (SOAP) from a provider. I have not control on the server response. For this I am using, Zend_Soap_Client passing the WDSL and options in the constructor, I can do getFunctions, but when try to access the first Soap method I get </p>
  
  <pre><code>[Sender] looks like we got no XML document
  </code></pre>
  
  <p>After looking around and checking the answer I get from the server with soapUI I see that the answer is missing the XML declaration:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="XXXXXXX"?&gt;
  </code></pre>
  
  <p>So, is there aby way to make the Zend_Soap_Client omit the XML validation based in the XML declaration? Assuming that the lacking of the declaration is my problem.</p>
  
  <p>Here is the code I use for this:</p>
  
  <pre><code>private $_connection_settings = array('login' =&gt; self::API_user, 'pwd' =&gt; self::API_password, 'key'=&gt; self::API_Key);
  
  
  private static $CONNEXION_PARAMS = array(                                            
                                          'soap_version'   =&gt; SOAP_1_1,
                                          'encoding'      =&gt; 'UTF-8'
                                       );
  
  ...
  
  //somewhere in my code: 
  
  $client = new Zend_Soap_Client('http://server_URL?wsdl', self::$CONNEXION_PARAMS);
  $response = $client-&gt;fistSoapMethod($this-&gt;_connection_settings);            
  </code></pre>
  
  <p>And response is not assigned.</p>
  
  <p>Thanks! </p>
