WCF Service returns an XML, how to prase using jquery?

i am calling an api for registration and if everything goes well then api returns an xml file

"<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\u000a<successNotification>\u000a\u0009<message>Successful web registration<\/message>\u0开发者_Python百科00a\u0009<registrationId>22342347<\/registrationId>\u000a<\/successNotification>"

if something wrong then it returns a line of message

you are missing something

my question is: how can i display message regardless whether it returns xml or just line of message:

$.getJSON('http://localhost:4126/service.svc/alert', { phoneNumber: '01231231233' },
   function (data) {
      var result = $(data).find('message').html;
      display.innerHTML = result;
 });

Use .get, return a string even when you are returning XML and parse it browser side with .parseXML would be one way.

$.get('http://localhost:4126/service.svc/alert', 
   { phoneNumber: '01231231233' },
   function (data) {
      var result;
      if(data.indexOf("<") >= 0) { // test for a character in XML but not the string
          var xmlDoc = $.parseXML(data);
          result = $(xmlDoc).find('message').html();
      } else {
          result = data;
      }
      display.innerHTML = result;
 },
 "text");
