Exception for missing data

Question

I was wondering what kind of exception should one throw for missing data. For example if an xml node doesn\'t contain data. It would be easy to \"throw new Exception(...

Answer 1

Do not call "throw new Exception", because you don't know how to handle the exception.

Define your own exception. Be more specific, such as XMLDataMissingException. Then you can give a meamingful message to user or log it.
