Jackson - Recursive parsing into Map<String, Object>

I'm trying to simplify my code: I want to store key and values (all strings).

I'm actually using a Map<String, Object> to store it. hat way Object could be a value (String) or a new node (Map<String, Object>).

How could I simplify this code? A recursive function would be good.

try {
    JsonParser jsonParser = new JsonFactory().createJsonParser(content);

    jsonParser.nextToken();
    while (jsonParser.nextToken() != JsonToken.END_OBJECT) {
        jsonParser.nextToken();

        if (jsonParser.getCurrentToken() == JsonToken.START_OBJECT) {
            while (jsonParser.nextToken() != JsonToken.END_OBJECT) {
                String key = jsonParser.getCurrentName();
                jsonParser.nextToken();

                if (jsonParser.getCurrentToken() == JsonToken.START_OBJECT) {
                    mData.put(key, new HashMap<String, Object>());
                    while (jsonParser.nextToken() != JsonToken.END_OBJECT) {
                        String subkey = jsonParser.getCurrentName();
                        jsonParser.nextToken();

                        if (jsonParser.getCurrentToken() == JsonToken.START_OBJECT) {
                            Map<String, Object> subdata = (Map<String, Object>) mData.get(key);
                            subdata.put(subkey, new HashMap<String, Object>());
                            while (jsonParser.nextToken() != JsonToken.END_OBJECT) {
                                String subsubkey = jsonParser.getCurrentName();
                                jsonParser.nextToken();
                                Map<String, Object> subsubdata = (Map<String, Object>) subdata.get(subkey);
                                LogHelper.d("data[" + key + "][" + subkey + "][" + subsubkey + "]=" + jsonParser.getText());
                                subsubdata.put(subsubkey, jsonParser.getText());
