Use Xerces – 2.0.2.jar if using jdk 1.6.

Directory structure in eclipse:

Sky.xml

 <?xml version="1.0"?>

<!DOCTYPE sky SYSTEM "sky.dtd">

<sky>

<employee>

<name>Sumit Kumar</name>

<email>sky@outlook.com</email>

</employee>

<employee>

<name>Sunil Kumar</name>

<email>skumar102@outlook.com</email>

</employee>

</sky>

<!ELEMENT sky (employee*)>

<!ELEMENT employee (name,email)>

<!ELEMENT name (#PCDATA)>

<!ELEMENT email (#PCDATA)>

SKYDOMReader.java:

package com.sky.parse.dom;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

import org.w3c.dom.Node;

import org.w3c.dom.NodeList;

public class SKYDOMReader {

      public static void main(String[] args) {

     

            try{

            DocumentBuilderFactory builderFactory=DocumentBuilderFactory.newInstance();

            DocumentBuilder documentBuilder=builderFactory.newDocumentBuilder();

            Document document=documentBuilder.parse("src/sky.xml");

            System.out.println("Root element :" + document.getDocumentElement().getNodeName());

            NodeList nodeList=document.getElementsByTagName("employee");

            for (int i = 0; i < nodeList.getLength(); i++){

                  Node node=nodeList.item(i);

                  Element eElement = (Element) node;

                      System.out.println("Name : "  + eElement.getElementsByTagName("name").item(0).getTextContent());

                      System.out.println("email : "   + eElement.getElementsByTagName("email").item(0).getTextContent());

            }

            }catch (Exception e) {

                  e.printStackTrace();

            }

           

      }

}

Output:
