How do I remove empty json nodes in Java with Jackson?

Question

I\'m a beginning java programmer, so I\'m sorry if my question is kind of dumb.

I have a JSON object that looks like this:

{
\"element1\" : {
    \"g

I haven't tested it, but you probably want something like this:

public static void stripEmpty(JsonNode node) {
    Iterator it = node.iterator();
    while (it.hasNext()) {
        JsonNode child = it.next();
        if (child.isObject() && child.isEmpty(null))
            it.remove();
        else
            stripEmpty(child);
    }
}
