Delphi WSDL importer issue

I am trying to import WSDL provided by a third party. In one of the methods (get_orders), looking at WSDL, it can return multiple records ( <part name="orders" type="tns:order" xsi:minOccurs="0" xsi:maxOccurs="unbounded"/>

), but Delphi creates a function that returns one object when I believe it should be an array. Am I doing something wrong?

WSDL file

Function created by delphi

function  get_orders: order; stdcall;  

      

        
        
        
      

    

Update 25/05/2015

The webservice returns something like this:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="urn:WashOut">
  <soap:Body>
    <tns:get_orders_response>
      <orders xsi:type="tns:orders">
        <number xsi:type="xsd:string">565474258</number>
        <total xsi:type="xsd:decimal">0.0</total>
      </orders>
      <orders xsi:type="tns:orders">
        <number xsi:type="xsd:string">519301205</number>
        <total xsi:type="xsd:decimal">0.0</total>
      </orders>
      <orders xsi:type="tns:orders">
        <number xsi:type="xsd:string">619118175</number>
        <total xsi:type="xsd:decimal">347.33</total>
      </orders>
      <orders xsi:type="tns:orders">
        <number xsi:type="xsd:string">105590906</number>
        <total xsi:type="xsd:decimal">127.74</total>
      </orders>
    </tns:get_orders_response>
  </soap:Body>
</soap:Envelope>

      

        
        
        
      

    

So, I may be asking the wrong question. How can I iterate over the "orders" returned from the web service using a block generated by the WSDL importer?
