here is solution with GSON

  • download GSON jar from above link add add it your buildpath

here i tried to parse the xml to get the json string and then parse the json to get the necessary elements from that

String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
        + "<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">"
        + "[{\"id\":3033,\"type\":\"cpt4\",\"description\":\"New Patient Office Visit  for Moderate to Severe problems- "
        + "Requiring Longer Visit\",\"category\":\"Office Visits\",\"subCategory\":\"Illness Related Visits\","
        + "\"inNetwork\":195.99,\"outNetwork\":424.06,\"code\":\"99205\",\"zip\":\"90210\",\"lastupdated\":\"2012-02-13T00:00:00.000-05:00\"}]"
        + "</string>";

Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
    DocumentBuilder db = dbf.newDocumentBuilder();
    InputSource is = new InputSource();
    is.setCharacterStream(new StringReader(xml));
    doc = db.parse(is);
} catch (Exception e) {
    e.printStackTrace();
}

doc.getDocumentElement().normalize();
String text = doc.getDocumentElement().getTextContent();
System.out.println(text);

try {
    // testing whether the json string is valid or not
    JsonParser jsonParser = new JsonParser();
    JsonElement jsonElement = jsonParser.parse(text);
    System.out.println("Valid JSon");

    System.out.println("isArray : " + jsonElement.isJsonArray());

    JsonArray jsonArray = jsonElement.getAsJsonArray();
    JsonObject jsonObject = jsonArray.get(0).getAsJsonObject();
    System.out.println("id : " + jsonObject.get("id"));
    System.out.println("type : " + jsonObject.get("type"));
    System.out
            .println("description : " + jsonObject.get("description"));
    System.out.println("category : " + jsonObject.get("category"));
    System.out
            .println("subCategory : " + jsonObject.get("subCategory"));
    System.out.println("inNetwork : " + jsonObject.get("inNetwork"));
    System.out.println("outNetwork : " + jsonObject.get("outNetwork"));
    System.out.println("code : " + jsonObject.get("code"));
    System.out.println("zip : " + jsonObject.get("zip"));
    System.out
            .println("lastupdated : " + jsonObject.get("lastupdated"));

} catch (JsonSyntaxException e2) {
    // TODO Auto-generated catch block
    e2.printStackTrace();
}

Note: - (ofcourse you can try without GSON and use native JSON parser )
