When to Use a Cursor or Event Iterator API
The cursor API is less verbose and less powerful than the event API. Presumably, it is more efficient at what it does and creates fewer temporary objects. Both the cursor and event iterator API are forward only API. However, the event iterator API provides a peek() feature to get the next event, as was demonstrated in SimpleXmlEventWriter. The event iterator API has many other capabilities that we didn't cover here, such as the ability to filter, buffer, persist, and compare events[i].
