Subject: WSDL Interface to EPO (European Patent Office)

Hi,
I am trying to do patent searches accessing the webservice at the
European patent office
(www.ops.epo.org/patents/patent-information/free/open-patent-services.html).

Here is the code I wrote:

____________________________________________________________
#step 1: SOAP method and parameters

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

#step 2: SOAP request and response

XSD::Charset.encoding = 'UTF8'

my_query = 'ti=green and ti=plant'
result = driver.biblio-search(my_query,1,3)

________________________________________________


Questions: How do I access the elements in result?
What do I do about this error message:
