Hi Friend,

Try the following code:

import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import java.io.*;
import java.util.*;
import java.text.SimpleDateFormat;

public class XMLParser{
Date date=new Date();
public static void main(String[] args) throws IOException{
XMLParser detail = new XMLParser("buyer.xml");
}
public XMLParser(String str){
try{
File file = new File(str);
if (file.exists()){
SAXParserFactory parserFact = SAXParserFactory.newInstance();
SAXParser parser = parserFact.newSAXParser();
System.out.println("XML Data: ");
DefaultHandler dHandler = new DefaultHandler(){
boolean id;
boolean name;
public void startElement(String uri, String localName,String element_name, Attributes attributes)throws SAXException{
if (element_name.equals("BuyersID")){
name = true;
}
if (element_name.equals("utcc:IssueDateTime")){
name = true;
}
}
public void characters(char[] ch, int start, int len) throws SAXException{
String str = new String (ch, start, len);
if (id){
System.out.println("id: "+str);
id = false;
}
if (name){
System.out.println("name: "+str);
name = false;
}
}
};
parser.parse(str, dHandler);
}
else{
System.out.println("File not found!");
}
}
catch (Exception e){
System.out.println("XML File hasn't any elements");
e.printStackTrace();
}
}
}

Thanks
