DDLSAX2FileHandler.h - description

begin: Tue Oct 23 2001 email: case@.nosp@m.ucdh.nosp@m.ep.uc.nosp@m.davi.nosp@m.s.edu

DDLSAX2FileHandler has the same structure as the DDLSAX2ConfigHandler as they both inherit from DDLSAX2Handler which inherits from Xerces C++ DefaultHandler. SAX2 is event driven. So, when the start of an element is encountered in the XML, then a call is made to the handler's startElement. The same for endElement.

The design of DDXMLElement allows for processing whichever type of Element the XML Parser encounters.
