Re: Seeking SAXException pattern

So I have this pattern all over my code. >> You could also throw a RuntimeException instead of a checked exception, if you don't want to wrap your exceptions or subclass SAXException; but most people do just wrap their exceptions and unwrap and rethrow them in a catch(SAXException) block around the parse. I think this sort of ugliness is pretty much inherent in a callback API, especially in Java. This is actually a very minor nit in working with SAX. You will likely soon the much bigger issues of whether or not the ErrorHandler is invoked for user-defined exceptions, and whether endDocument is or is not called for which exceptions. None of this is sufficiently standardized. All of it varies from one parser to the next. Assume nothing. -- Elliotte Rusty Harold elharo@m...
