You can use this method to correct the SOAP request before sending it, if necessary. You can use the DOM API to accomplish that. 



<?php



public ExtendedClient extends SoapClient {



   function __construct($wsdl, $options = null) {

      parent::__construct($wsdl, $options);

   }



   function __doRequest($request, $location, $action, $version) {

      $dom = new DOMDocument('1.0');



      try {



         //loads the SOAP request to the Document

         $dom->loadXML($request);



      } catch (DOMException $e) {

         die('Parse error with code ' . $e->code);

      }



      //create a XPath object to query the request

      $path = new DOMXPath($dom);



      //search for a node

      $nodesToFix = $path->query('//SOAP-ENV:Envelope/SOAP-ENV:Body/path/to/node');



      //check if nodes are ok

      $this->checkNodes($path, $nodesToFix);



      //save the modified SOAP request

      $request = $dom->saveXML();

      

      //doRequest

      return parent::__doRequest($request, $location, $action, $version);

   }



   function checkNodes(DOMXPath $path, DOMNodeList $nodes) {

      //iterate through the node list

      for ($i = 0; $ < $nodes->length; $i++) {

         $aNode = $nodes->item($i);



         //just an example

         if ($node->nodeValue == null) { 

            //do something. For instance, let's remove it.

            $node->parentNode->removeChild($node);

         }

      }

   }

}

?>



This gives the developer the chance to solve interoperability problems with a web service.
