CodeIgniter and WebService Consuptions (Sending xml with parameters)

Hello I am using CodeIgniter to consume a web service. I am having the following problem. I been trying with soapUI and I can send the xml well-formated and it works, which is:

<soapenv:Envelope xmlns:soapenv="http://ift.tt/sVJIaE" xmlns:ser="http://ift.tt/1kFTvA1">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:ExecTransaction>
<xmlMessage>
<![CDATA[
<Message>
     <client>
          <clientId>2323</clientId>
     </client>      
</Message>]]>
         </xmlMessage>
      </ser:ExecTransaction>
   </soapenv:Body>
</soapenv:Envelope>

This works perfectly in soapUI. Now I try to send this xml well formatted through CodeIgniter in this way:

xmlMessage.xml.php

<![CDATA[
<Message>
     <client>
          <clientId>2323</clientId>
     </client>      
</Message>]]>

This is the code of the controller in CodeIgniter:

    $xmlMessage = $this->load->view('xmlMessage.xml.php', $data, true);

    try {
        $client = @new SoapClient($this->config->item('soapTransactionService'));
    }
    catch (Exception $e) {
        print_r ($e);
        exit;
    }

    $result = $client->ExecTransaction(
    array(
        'xmlMessage' => $xmlMessage 
    ));

And in this line where I call ExecTransaction I am getting an error ("Uncaught SoapFault exception") It is the same error that I get when I send a non-well formatted XML to the Webservice. So the problem is in the way that I formatted the XML. Any ideas how to solve this?

Thank you very much
