As I just mentioned in a reply to Don, exceptions provide for cleaner
code and they help avoid bugs by enabling more compile-time checking.
It's easy to write

  parser.setFeature("org.xml.sax.features.namespaces", true);

and forget to check the return value, but it's harder to forget to
catch an exception.


All the best,


David
