I am a newbie to json parsing, I have grabbed a json string from a request and now I need to parse it with java. I'm using simple-lib for this. But I'm really stuck as I'm not familiar with it. I need to extract following data
I used following java code for that but it's not giving me the result I need, please someone help me...
JSONParser parser = new JSONParser();
try {
Object obj = parser.parse(new FileReader("test.json"));
JSONObject jsonObject = (JSONObject) obj;
JSONArray msg = (JSONArray) jsonObject.get("content");
Iterator<String> iterator = msg.iterator();
while(iterator.hasNext()) {
System.out.println(iterator.next());
}
Sample JSON
{
"status": 200,
"message": "ok",
"timestamp": "2014-05-22T14:29:56.824+03:00",
"pagesCount": 1,
"version": "1.1",
"pages": [
{
"number": 100,
"subpages": [
{
"number": 1,
"timestamp": "2014-05-22T13:41:41.116+03:00",
"content": "text"
},
Something like this perhaps?
JSONParser parser = new JSONParser();
JSONObject jsonObject = (JSONObject) parser.parse(new FileReader("test.json"));
JSONArray pages = (JSONArray) jsonObject.get("pages");
if (pages != null) {
for (Object p : pages) {
JSONObject page = (JSONObject) p;
JSONArray subPages = (JSONArray) page.get("subpages");
if (subPages != null) {
for (Object sp : subPages) {
JSONObject subPage = (JSONObject) sp;
System.err.println(subPage.get("content"));
}
}
}
}
