I couldn't understand questions 1 & 2, so I haven't answered them.

| 3/ If i understand the event-based philosophy, an XML parser do not

| Comment()" called within the code of the parser !) ?

That's right. A sensible way to deal with this might be to take a
layered approach and give the parser just a simple SAX-like event
interface with callbacks for all the different events.

Then, you might make a special client to the event interface that uses
the event callbacks to build a DOM tree.

Your event interface would probably have more events than SAX, so a
SAX driver would probably use another special event client that only
echoed some of the events to the SAX handlers.
