Get element attributes in SAX XML parsing

In this example we shall show you how to get an Element’s Attributes using SAX XML parsing. Simple API for XML (SAX) is an event-driven, serial-access mechanism for accessing XML documents. It is frequently used by servlets and network-oriented programs that need to transmit and receive XML documents, because it is the fastest and least memory-intensive mechanism that is currently available for dealing with XML documents, other than the Streaming API for XML (StAX). We have created a Class, GetElementAttributesInSAXXMLParsing that is a handler that extends the DefaultHandler and overrides its startElement(String uri, String localName, String qName, Attributes attributes) API method. The basic steps of the example are described below:

  • Create a new instance of the GetElementAttributesInSAXXMLParsing class.
  • Obtain a new instance of a SAXParserFactory, that is a factory API that enables applications to configure and obtain a SAX based parser to parse XML documents.
  • Set the parser produced by this code so as not to validate documents as they are parsed, using setValidating(boolean validating) API method of SAXParserFactory with validating set to false.
  • Create a new instance of a SAXParser, using newSAXParser() API method of SAXParserFactory.
  • Use parse(File f, DefaultHandler dh) API method of SAXParser to parse the content of the specified XML file, using the specified handler of the example. The handler that we have implemented, overrides the startElement(String uri, String localName, String qName, Attributes attributes) API method of DefaultHandler. In this method, for each one of the given Attributes it takes its qualified (prefixed) name, its value, namespace URI and local name, using getQName(int index), getValue(int index), getURI(int index) and getLocalName(int index) API methods of Attributes,

as described in the code snippet below. 

package com.javacodegeeks.snippets.core;


import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class GetElementAttributesInSAXXMLParsing extends DefaultHandler {
	public static void main(String[] args) throws Exception {
		DefaultHandler handler = new GetElementAttributesInSAXXMLParsing();

		SAXParserFactory factory = SAXParserFactory.newInstance();



  SAXParser parser = factory.newSAXParser();


  parser.parse(new File("in.xml"), handler);
	public void startElement(String uri, String localName, String qName,
			Attributes attributes) throws SAXException {
		// get the number of attributes in the list

  int length = attributes.getLength();

  // process each attribute

  for (int i=0; i<length; i++) {


// get qualified (prefixed) name by index

String name = attributes.getQName(i);

System.out.println("Name:" + name);

// get attribute's value by index.

String value = attributes.getValue(i);

System.out.println("Value:" + value);

// get namespace URI by index (if parser is namespace-aware)

String nsUri = attributes.getURI(i);

System.out.println("NS Uri:" + nsUri);

// get local name by index

String lName = attributes.getLocalName(i);

System.out.println("Local Name:" + lName);
