Why does this xpath not work

[Mikael Petterson]

Hi,

I am trying the below code. I want to get the value for ‘network’ name.
I put a breakpoint System.out.println("test");
And there is nothing in selectPath.

What am I missing?

//mike

public static void main(String[] args) throws Exception {
              RpcReply newRpcReply = NetconfRpc.newRpcReply(reply());
              String expression = 
"$this/ericsson-sbg-function---n22-cl2-ims1-pcscf-1-1---1-6-0-931/pcscf/access-net-pcscf/network-name/text()";
              XmlObject[] selectPath = 
newRpcReply.toXmlObject().selectPath(expression);
              System.out.println("test");
       }

       private static String reply() {
              return "<rpc-reply 
xmlns=\"urn:ietf:params:xml:ns:netconf:base:1.0\" message-id=\"272\">\r\n"
                           + "<data>\r\n"
                           + "

                           + "</data>\r\n"
                           + "</rpc-reply>";
       }
