But in reality, none of the main parsers have all these features at the same time.

By contrast, however, an event-based API provides interfaces on handlers.

At this time, we may also say, one event has occurred.

A SAX parser reads the document character by character or token by token.

The following callback methods are provided in both of them (note, although callback methods are typically used in SAX parser as I mentioned before, Xerece J's DOMParser actually also provides most of these callback methods) Yes, of course, because the use of a DOM parser and a SAX parser is independent.

For example, if your application needs to work on two XML documents, and does different things on each document, you could use a DOM parser on one document and a SAX parser on another, and then combine the results or make the processings cooperate with each other.

If, however, the instructor adopts such a grading policy that the students who got 90 points or more, are assigned A's and the others are assigned B's, then probably he'd better use a SAX parser.
