Answer 1

Are you sure you have implemented the handler correctly? You still lack characters() and endElement().

startElement() is only used to identify the tag you’re reading. Use a temporary variable to store stuff in characters(), and save the data in endElement().

Maybe that is the problem. I’m not sure.
