Re: Java and XML

[dbestk <dbestk@yahoo.com>]

I agree with Ron.  Returning a collection of objects
is going to be a lot faster than returning an XML
document.  If you return a collection, you can use the
Iterator interface to navigate through the collection.
 Same goes for passing in an xml document as a
parameter to a method call.  XML is nice for passing
information to external clients or maybe storing your
data in a config file, but using XML internally to
applications doesn't seem like a very good or
efficient way to do things.
