Subject: Attributes for Soap elements

Hi,

I'm accessing a web service that is largely using attributes rather
than elements for the request. How can I create a request containing
attributes?

I create the SOAP driver with

  require 'soap/wsdlDriver'
  driver = SOAP::WSDLDriverFactory.new(wsdlURL).create_rpc_driver

and can elicit appropriate responses from the server for requests that
pass the data as elements:

  driver.getSomething(:foo=>"bar")

However, most requests require the data to be passed as attributes.
For example, a simplified WSDL reads in part

   <element name="GetItem">
    <complexType>
     <sequence>
      <element name="itemRequest" type="impl:GetItemRequest"/>
     </sequence>
    </complexType>
   </element>
      <complexType name="GetItemRequest">
    <sequence/>
    <attribute name="X" type="xsd:double"/>
    <attribute name="Y" type="xsd:double"/>
  </complexType>

How will I craft a request to the GetItem service with appropriate
values for X and Y?

Thanks,
Roy.
