How to parse array from JsonArray?

Question

I have JSON array like

"Headlines": [
 {
 "Title": "SPYRUS Announces Support for Windows To Go 10 Preview",
 "Date": "2/18/2015",
 "UTCOffset": 0,
 "Source": "Marketwire - News Releases",
 "Url": "http://www.redinews.com/news/?story=201502151176008.html",
 "Images": [],
 "Tags": [
 {
 "TagType": "Symbols",
 "TagValues": [
 "MSFT"
 ]
 },
 {
 "TagType": "Companies",
 "TagValues": [
 "Microsoft Corporation"
 ]
 },

I am accessing "Headlines" with this code using org.json.simple.parser.JSONParser

 JSONParser jsonParser = new JSONParser();
 JSONObject jsonObject = (JSONObject) jsonParser.parse(obj);
 JSONArray lang = (JSONArray) jsonObject.get("Headlines");
 System.out.println(lang);

but I need access "Tags" sub array and get TagType and TagValues

How to access it? will be good also know how to parse sub array with org.codehaus.jackson.

Thanks

Answer 1

see this link.

it explains how to iterate over an json array

the code should be something like this

JSONArray headlines = (JSONArray) jsonObject.get("Headlines");
 Iterator<String> iterator = headlines.iterator();
 while (iterator.hasNext()) {
 System.out.println(iterator.next());
 }

Answer 2

Check this

JSONParser jsonParser = new JSONParser();
 JSONObject jsonObject = (JSONObject) jsonParser.parse(obj);
 JSONArray lang = (JSONArray) jsonObject.get("Headlines");
JSONArray tag = lang.getJSONArray("tag"); 
for (int i = 0; i < tag .length(); i++) {
 JSONObject jsonobject = jsonarray.getJSONObject(i);
 JSONArray temp= jsonobject .getJSONArray("TagValues"); 
 String tagValue = temp.getString(0);
 String tagType = jsonobject.getString("TagType");
 }

Answer 3

Here is a code which really work, used simple json and org.codehaus.jackson togheter.

JSONParser jsonParser = new JSONParser();
 JSONObject jsonObject = (JSONObject) jsonParser.parse(obj);
 JSONArray lang = (JSONArray) jsonObject.get("Headlines");
 for (int i = 0; i < lang.size(); i++) {
 JSONObject jsonobject = (JSONObject) lang.get(i);
 Object subArray = jsonobject.get("Tags");
 ObjectMapper mapperNew = new ObjectMapper();
 JsonFactory factoryNew = mapperNew.getJsonFactory();
 JsonParser jpNew;
 System.out.println("sub Array " + subArray.toString());
 jpNew = factoryNew.createJsonParser(subArray.toString());
 JsonNode inputNew = mapperNew.readTree(jpNew);
 for (final JsonNode elementNew : inputNew) {
 Iterator<Map.Entry<String, JsonNode>> nodeIterator3 = elementNew.getFields();
 while (nodeIterator3.hasNext()) {
 Map.Entry<String, JsonNode> entry3 = (Map.Entry<String, JsonNode>) nodeIterator3.next();
 if (entry3.getKey() != null && entry3.getKey().equals("TagType")) {
 System.out.println("TagType " + entry3.getValue());
 }
 if (entry3.getKey() != null && entry3.getKey().equals("TagValues")) {
 System.out.println("TagValues " + entry3.getValue());
 }
 }
 }
