Receiving Events with SAX

 

The following are the building blocks of a typical SAX application.

SAXXMLReader
SAXXMLReader implements the ISAXXMLReader interface. SAXXMLReader consumes the XML and throws events to the handlers that you set for the reader. First you create an instance of SAXXMLReader, and then set a ContentHandler and an ErrorHandler for receiving events from the reader.

IVBSAXContentHandler
The ContentHandlerImpl.cls class implements the IVBSAXContentHandler interface. IVBSAXContentHandler catches events thrown by the reader. The main events are: startDocument, endDocument, startElement, endElement, and characters.

IVBSAXErrorHandler
The ContentHandlerImpl.cls class implements the IVBSAXErrorHandler interface. IVBSAXErrorHandler catches any errors raised during the read process. At this time, MSXML supports only the fatalError method.

Application
The application consists of code that typically creates an instance of the SAXXMLReader, sets the content handler and error handler for the reader, and then calls the parse or parseURL method of the SAXXMLReader to process an XML file.
