How to make SOAP call using native SoapClient in PHP?

Question

I want to make a call to web service, which is also under development, and which has one function defined within WSDL, PlaceInvoiceFromStream. Function defines one argument to be passed, Invoice. WSDL imports types defined within XSD shema.

WSDL looks like this:

Schema looks like this:

UBL 2.1 Schemas: http://docs.oasis-open.org/ubl/prd2-UBL-2.1/UBL-2.1.html#SCHEMAS

Invoice is complex data, saved in XML file, and which contains namespaces and attributes. It starts like this:



    
        
            INVOICE1
            InvoiceIssuePlaceData
            urn:invoice:issueplace
            
                MyCity
            
        
    
    2.1
    01 1206-2406-568`

etc...

I have tried this approach:

// LOAD XML and TRANSFORM FOR SoapClient 
$xmlfile = "Invoice123.xml";
$xslfile = "xsltForSoapClientRequest.xsl";
$xmlDOM = new DOMDocument();
$xmlDOM->load($xmlfile);
$xslDOM = new DOMDocument();
$xslDOM->load($xslfile);
$proc = new XSLTProcessor;
$proc->importStyleSheet($xslDOM);
$transformedXML = $proc->transformToDoc($xmlDOM);
$xmldoc = simplexml_load_string($transformedXML);

// CREATE ARRAY
$xmlarr = xml2array($xmldoc->asXML());

$client = new SoapClient($wsdl,array('trace'=>1));
$result=$client->PlaceInvoiceFromStream($xmlarr);

but with no success.

XSL transformation changes are:

node attribute becomes node element
complex node value becomes "_" element

xml2array changes are:

attributes becomes separate array

So, $xmlarr to be sent to web service function is in the following form:

array(2) {
  ["Invoice"]=>
  array(15) {
    ["ext:UBLExtensions"]=>
    array(1) {
      ["ext:UBLExtension"]=>
      array(4) {
        ["cbc:ID"]=>
        string(10) "INVOICE1"
        ["cbc:Name"]=>
        string(21) "InvoiceIssuePlaceData"
        ["ext:ExtensionAgencyURI"]=>
        string(25) "urn:invoice:issueplace"
        ["ext:ExtensionContent"]=>
        array(1) {
          ["ext:InvoiceIssuePlace"]=>
          string(7) "MyCity"
        }
      }
    }
    ["cbc:UBLVersionID"]=>
    string(3) "2.1"
    ["cbc:ID"]=>
    string(16) "01 1206-2406-568"
...

  ["Invoice_attr"]=>
  array(8) {
    ["xmlns"]=>
    string(54) "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
    ["xmlns:xsi"]=>
    string(41) "http://www.w3.org/2001/XMLSchema-instance"
    ["xmlns:cac"]=>
    string(72) "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
    ["xmlns:cbc"]=>
    string(68) "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
    ["xmlns:sac"]=>
    string(75) "urn:oasis:names:specification:ubl:schema:xsd:SignatureAggregateComponents-2"
    ["xmlns:ext"]=>
    string(72) "urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
    ["xmlns:sig"]=>
    string(72) "urn:oasis:names:specification:ubl:schema:xsd:CommonSignatureComponents-2"
    ["xsi:schemaLocation"]=>
    string(93) "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2 http://localhost/ebiz/ws/Invoice.xsd"
  }
}

The result of the web service call is:

SOAP-ERROR: Encoding: object has no 'UBLExtensions' property

What should be the form for the correct SOAP request? What form of the array is expected for SOAP request? Does SOAP understands, based on WSDL and XSD, that "_" element? Or attributes in the separate array?

Thanks in advance for any help in fixing this issue...

UPDATE:

changed wsdl:

SoapClient accepts following request:

$xmlarr = array(
    "UBLExtensions"=>
    array(
      "UBLExtension"=>
      array(
        "ID"=>"INVOICE1",
        "Name"=>"InvoiceIssuePlaceData",
        "ExtensionAgencyURI"=>"urn:invoice:issueplace",
        "ExtensionContent"=>
        array(
          "InvoiceIssuePlace"=>"MyCity"
        )
      )
    ),
    "UBLVersionID"=>"2.1",
    "ID"=>"01 1206-2406-568",
    ...

which is not what I want. I need namespaces in keys. What should be changed/added to make SoapClient able to accepts namespaces within keys in the request array, like i.e. "ext:UBLExtensions"?
