We have already discussed about the DOM Parser of JAXP<\/a>. This article will focus on Reading XML file using SAX Parser:<\/p>\n

\"SAX<\/a>
SAX Parser<\/figcaption><\/figure>\n

SAXParser object can obtained from the SAXParserFactory <\/strong>and then we can process the document using that parser.
\nThe most important interface in SAX parser class is ContentHandler<\/strong>. This interface requires a number of methods that the SAX parser invokes in response to various parsing events. The major event-handling methods are: startDocument, endDocument, startElement, and endElement.<\/strong>
\nThe easiest way to implement this interface is to extend the DefaultHandler <\/strong>class, defined in the org.xml.sax.helpers<\/strong> package. That class provides do-nothing methods for all the ContentHandler events.<\/p>\n

The example program extends that class.
\npublic class SAXLocalNameCount extends DefaultHandler {<\/strong><\/p>\n

Example :<\/p>\n

Locator to indicate the current position of SAX Parser.<\/em><\/p>\n
