My WCF service returning xml data e.g.

<stundent><name>abc</name></student>

But while consuming in android they are getting same data as
like <student><name>

In my WCF service return paramter is normal C# string.
At my WCF service end in log file we are writing the response before sending to client app end and its writing proper xml string but while client end its converting as like above.

Client is unable to convert the code as their end their middle ware is converting the same.
my service is code is below :

[DataContract]
  public class RespServiceData
  {
      [DataMember]
      public string RespData { get; set; }
  }

Is their anything which i can change at service end so that problem will solve.
