Re: [json-lib-user] use dot notation implemented anywhere?

[Ben A. <tw....@gm...>]

well, here's the simple implementation I put in one of my utility classes
(THIS IS UNTESTED):

    public static Object dot(JSONObject jo, String notation) {
        Object o =3D null;
        try {
            String[] tokens =3D notation.split(".");
            for (int i=3D0; i<(tokens.length-1); i++) {
                jo =3D jo.optJSONObject(tokens[i]);
            }
            o =3D jo.opt(tokens[tokens.length-1]);
        } catch (Exception e) {
            // do nothing
        }
        return o;
