Smack receiving messages in XML format can i change them to JSON?

I am developing an android chatting app with the use of Openfire as a support server for XMPP and smack library as a android implementation of XMPP.

Things are going well. Till i find this received message from another user. The format is like this :

<message to="rajesh2@peacock-hp" id="0mpqe-10" type="chat" from="rajesh1@peacock-hp/Smack">
   <body>{"Date":"8 Jul 2016","Time":"0:40p.m.","body":" vhklv","isMine":true,"msgid":"909-08","receiver":"rajesh2","sender":"rajesh1","senderName":"rajesh1"}</body>
   <thread>06ed73bb-21ad-4276-80cb-0ea4fc9d9dfb</thread>
</message>

My listener which is receiving messages :

private class MMessageListener implements ChatMessageListener {

    public MMessageListener(Context contxt) {
    }

    @Override
    public void processMessage(final org.jivesoftware.smack.chat.Chat chat,
                               final Message message) {
        Log.i("MyXMPP_MESSAGE_LISTENER", "Xmpp message received: '"
                + message);

    }

}

My Question is : Can i receive this message in JSON format instead of XML ??

As I am learning smack and xmpp please guide me if i am wrong at some places. correct me if any one of you find me wrong.

Json it's not the reply format for Openfire. Of course, you can rewrite all Openfire to "talk" in Json, but to me has no sense.

What I suggest to you:

  • if you have a performance issue, you can look maybe for Ejabber
  • If you need a Json, maybe Prosody IM has a plugin
  • If you don't want to broke your head with XmlPullParser, give a try to Bubbler in alternative to Smack.
  • If you just don't feel confident with XML, just implement a "toJson" for each Stanza type so you'll have something like
    (thanking @Khan)
MyMessage extends Message

public String toJson()
{
JSONObject xmlJSONObj = XML.toJSONObject(this.toXML());
        String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
}

and you'll be able to use a Json.

You can convert messages to JSON format through a project on Github.

Example :

public class Main {

  public static int PRETTY_PRINT_INDENT_FACTOR = 4;
  public static String TEST_XML_STRING =
    "<?xml version=\"1.0\" ?><test attrib=\"moretest\">Turn this to JSON</test>";

  public static void main(String[] args) {
    try {
        JSONObject xmlJSONObj = XML.toJSONObject(TEST_XML_STRING);
        String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
        System.out.println(jsonPrettyPrintString);
    } catch (JSONException je) {
        System.out.println(je.toString());
    }
  }
}

Output is:

{
  "test": {
     "attrib": "moretest",
     "content": "Turn this to JSON"
   }
}

Credit goes to Quickest way to convert XML to JSON in Java
