Subject: SOAP Client -getting data from SOAP::Mapping::Object?

I've been staring at this for too long, and at this point my mind can't
think clearly enough to continue without help...   I've never worked
with SOAP before, so forgive me if I'm overlooking something simple.

I'm using Ruby to access data via SOAP from a server (using soap4r and
http-access2).  I know I'm connecting successfully and getting the right
information, but don't know how to access the data from the response.
I've been testing with irb using the following:

require 'soap/wsdlDriver'
require 'http-access2'
wsdl = './proton.wsdl'
driver = SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
driver.options["protocol.http.cookie_store_file"] = './cookie.file'
driver.login('username', 'password')
result = driver.getEntities('2588676', 'IPv4Network', '0', '0')
driver.logout

The URL for the SOAP server is read correctly from the wsdl file, and
the methods "login" and "getEntityById" are also read from the wsdl.
"result" is an array with only one element:
"result[0].class => SOAP::Mapping::Object"

The result itself looks like a single string concatenating each of the
elements received in the response:

irb(main):013:0> result[0]
=> #<SOAP::Mapping::Object:0xac7e34
{http://api.proton}value=#<SOAP::Mapping::Object:0xac7cea
{http://api.proton}id="2588677"
{http://api.proton}name=#<SOAP::Mapping::Object:0xac78f8>
{http://api.proton}properties=#<SOAP::Mapping::Object:0xac751a>
{http://api.proton}type="IPv4Network">>

According to the WSDL, the response should be type APIEntity.Array,
which is composed of APIEntity objects with "id", "name", "properties",
and "type" elements (all defined in the wsdl).  So it looks like I'm
very close to having the data where I can actually use it (as an
accessible object or even an array), but I'm just not there yet.  Can
anyone tell me how to get the data out of the SOAP::Mapping::Object
objects?

Thanks!
