webservice

In my project I consumed a webservice, which electronically signs the pdf documents. So I got the response from web method as SOAP object as follows.

   soap:Envelope [ xmlns:soap=http://schemas.xmlsoap.org/soap/envelope/ ]
|
+  soap:Body
 |       
 + ns2:callArgsResponse [ xmlns:ns2=http://webservice.api.cabaret.com/ ]
   |
   + return [ xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance xsi:type=ns2:map ]
     |
     + entries
             |
             + name
                  | 
                  name
             + value [ xmlns:xs=http://www.w3.org/2001/XMLSchema xsi:type=xs:string ]
                  |
                  1801.pdf
     + entries
             |
             + name
                  |
                  content
             + value [ xmlns:xs=http://www.w3.org/2001/XMLSchema xsi:type=xs:base64Binary ]
                  |

My concern is how to read this object? The object comes in "XmlNode[]" type.
What will be the best and generic way ,so that i can read the values of "entries" from response object?

What I have tried:

I tried to deserialize the object but not able to do it. I can do it by traversing the node one by one.
I want to do it by optimize way. How can i achieve it?
