How do you use a SAX parser?
SAX parser methods to override
The important methods to override are startElement() , endElement() and characters() . SAXParser starts parsing the document, when any start element is found, startElement() method is called. We are overriding this method to set boolean variables that will be used to identify the element.
How do you make a SAX parser?
Using a SAX Parser
- Import the JAXP classes.
- Get an instance of the SAXParserFactory class.
- Using the instances of the SAXParserFactory class and the SAXParser class, generate an instance of the parser.
- Get the XMLReader from the SAXParser instance.
- In the XMLReader, register an instance of the event-handling classes.

What is the advantage of SAX parser?
The general advantages of SAX include: The nature of a streaming model means that you need far less memory to process large XML documents. You do not have to process the entire document. Use callback procedures to identify and respond to only the XML elements you are interested in.
What is SAX in WT?
