Hmm.  It seems that the wsdl uses for literal encoding(no encoding).
Can I see entire definition of the wsdl?

Wsdl2ruby.rb only supports SOAP Encoding now...  With SOAP Encoding,
WSDL should be like this;

      <xsd:complexType name="MyStruct">
        <xsd:sequence>
          <xsd:element name="boolean" type="xsd:boolean"/>
          <xsd:element name="int" type="xsd:int"/>
          <xsd:element name="double" type="xsd:double"/>
          <xsd:element name="string" type="xsd:string"/>
        </xsd:sequence>
      </xsd:complexType>

      <xsd:complexType name="MyStructArray">
        <xsd:complexContent>
          <xsd:restriction base="soapenc:Array">
             <xsd:attribute ref="soapenc:arrayType"
                 wsdl:arrayType="typens:MyStruct[]"/>
          </xsd:restriction>
        </xsd:complexContent>
      </xsd:complexType>

To access literal encoding SOAP service, without WSDL,
soap4r/sample/soap/icd/* may help you.  In short example,
following should work.

  require 'soap/rpc/driver'
  server = ARGV.shift
  drv = SOAP::RPC::Driver.new(server, "urn:serviceNamespace")
  # This line is for literal encoding -> language mapping which has
  #   its origin in ASP.NET.
  drv.default_encodingstyle = SOAP::EncodingStyle::ASPDotNetHandler::Namespace
  drv.add_method("getChannelList")

  drv.getChannedList.Channel.each do |ch|
    p ch
  end

Using wsdl2ruby.rb is a must?

With SOAP Header, not embedding auth data into SOAP Body?
There is very low level API for now...  An example is in
soap4r/sample/soapbox/* but I must add high level API and examples
for it.
