Create new DocumentBuilderFactory

   <source lang="java">

import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.ParserConfigurationException; public class TryDOM {

 public static void main(String args[]) {
   DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
   DocumentBuilder builder = null;
   try {
     builder = builderFactory.newDocumentBuilder();
   } catch (ParserConfigurationException e) {
     e.printStackTrace();
     System.exit(1);
   }
   System.out.println("Builder Factory = " + builderFactory + "\nBuilder = " + builder);
 }
