Creating an Iterator

The next step is to create an iterator to parse the stream:

while(reader.hasNext()) {
    XMLEvent event = (XMLEvent)reader.next();
    if (event.getEventType() == event.CHARACTERS) {
        writer.add(ms.getNewCharactersEvent(event.asCharacters()));
    } else {
        writer.add(event);
    }
}
writer.flush();
