Hello Alberto, thanks for the replies
I have implemented a class that has derived from DOMErrorHandler
and implemented the handleError method of that class.
Is this fine or the ErrorHandler interface itself must be implemented?
The DOMErrorHandler should be used with the DOMBuilder parser; the
ErrorHandler should be used with the XercesDOMParser parser.
They do the same job, but are different interfaces.

Yes

You need to declare a class deriving from the ErrorHandler interface,
and implement its virtual methods; the XML engine will call the
warning(), error() or fatalError() method of the interface whenever an
error occurs. You can then throw a custom exception to abort parsing, or
simply store the message in the class and let the XML engine try to
continue parsing/validating.
