Hi,

I am trying to parse variables from a simple data structure/class… I am  
using a web service and it returns a data structure. Here is the code:

@result = ws.HelloWorld(nil)  
puts @result.inspect # line 15  
puts @result.HelloWorldResult # line 16

#\<SOAP::Mapping::Object:0x174c2b4  
{[http://tempuri.org/](http://tempuri.org/)}HelloWorldResult=“Hello World”\> # line 15  
rms\_wsdl.rb:16: undefined method `HelloWorldResult’ for  
#SOAP::Mapping::Object:0x2e98448 (NoMethodError)

I am sure, I am missing something very basic. Any help would be greatly  
appreciated.

Thanks in advance.

Prad

To Clarify more, How would I get the data “Hello World” out from the  
data structure:

Thanks,

Try using p @result.methods to figure out what the method is called.  
Either that or show some more code (where the object gets created).

After reading the source for SOAP::Mapping::Object my guess is  
@result[“HelloWorldResult”] will give you what you want

Here is the code. I want to get the value returned by the web service,  
in this case text “Hello World”. see below HelloWorldResult=“Hello  
World”

Thanks a lot,

* * *

require ‘soap/wsdlDriver’

RMS\_WSDL =  
‘[http://host.com/webservice1/trackermapper/service1.asmx?WSDL](http://host.com/webservice1/trackermapper/service1.asmx?WSDL)’  
ws = SOAP::WSDLDriverFactory.new(RMS\_WSDL).create\_rpc\_driver

puts ws.inspect

@result = ws.HelloWorld(nil)  
puts @result.inspect  
puts @result.HelloWorldResult

* * *

and the output is

#\<SOAP::Mapping::Object:0x174c2b4  
{[http://tempuri.org/](http://tempuri.org/)}HelloWorldResult=“Hello World”\>  
rms\_wsdl.rb:16: undefined method `HelloWorldResult’ for  
#SOAP::Mapping::Object:0x2e98448 (NoMethodError)
