How to use nuSOAP for messages with multiple namespaces

I’m trying to access a WebService using nuSOAP (because I’m bound to PHP4 here) that uses more than 1 namespace in a message. Is that possible?

An example request message would look like this:

<soapenv:Envelope ...
  xmlns:ns1="http://domain.tld/namespace1"
  xmlns:ns2="http://domain.tld/namespace2">
  <soapenv:Header/>
  <soapenv:Body>
    <ns1:myOperation>
      <ns2:Person>
        <ns2:Firstname>..</ns2:Firstname>
        ..
      </ns2:Person>
      <ns1:Attribute>..</ns1:Attribute>
    </ns1:myOperation>
  </soapenv:Body>
</soapenv:Envelope>

I tried to following:

$client = new nusoap_client("my.wsdl", true);
$params = array(
  'Person' => array(
    'FirstName'  => 'Thomas',
    ..
   ),
   'Attribute' => 'foo'
 );

 $result = $client->call('myOperation', $params, '', 'soapAction');

in the hope that nuSOAP would try to match these names to the correct namespaces and nodes. Then I tried to use soapval() to generate the elements and their namespace – but if I call an operation, nuSOAP creates the following request:

<SOAP-ENV:Envelope ...>
  <SOAP-ENV:Body>
    <queryCCApplicationDataRequest xmlns="http://domain.tld/namespace1"/>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

So something goes wrong during the “matching” phase.

Answer

After trying around with the matching, I found two possible solutions:

1) Don’t use the WSDL to create the nusoap_client and soapval() to create the message This has the disadvantage that the message contains a lot of overhead (the namespace is defined in each element). Not so fine.

2) Instead of relying on the matching of parameters, construct your reply in xml and put all the definition for prefixes in the first element – e.g.

$params = "<ns1:myOperation xmlns:ns1="..." xmlns:ns2="...">
      <ns2:Person>
        <ns2:Firstname>..</ns2:Firstname>
        ..
      </ns2:Person>
      <ns1:Attribute>..</ns1:Attribute>
    </ns1:myOperation>";

Still not a very nice solution, but it works 🙂
