3.0 Further acronyms SAX (simple API for XML) and DOM (document object model).

3.1 SAX

• Both SAX and DOM are application programming interfaces which basically equates to a set of classes that define a standard set of mechanisms to read and write XML data.

• The SAX API is an event-driven protocol, because the technique works by first registering handlers with the SAX parser, after which the parser invokes the callback methods whenever it sees an XML tag.

• The methods in this handler class perform the application-specific functionality during the parse.

• The SAX API is one of the simplest interfaces to use and handle XML.

• There are a number of implementations in different programming languages (C, java, C++, etc).
