<Customers>

you can find the above xml there is no CountryCode in the second record and 4th records.
if that CountryCode is not present then i need to skip the total Customer tag.
so we were using the sax parcing in our application. can you please let me know... how to handle this code in SAX Parcing.

Hi Friend,

First of all remove & sign from your xml file,it contradicts.And then try the following code:

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

public class XMLParser{
Date date=new Date();
public static void main(String[] args) throws IOException{
XMLParser detail = new XMLParser("C:/customers.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 name;
boolean id;
boolean ccode;
boolean bcode;
boolean ano;

public void startElement(String uri, String localName,String element_name, Attributes attributes)throws SAXException{
if (element_name.equals("CustName")){
name = true;
}
if (element_name.equals("CustId")){
id = true;
}
if (element_name.equals("CountryCode")){
ccode = true;
}
if (element_name.equals("BranchCode")){
bcode = true;
}
if (element_name.equals("AccountNbr")){
ano = true;
}
}
public void characters(char[] ch, int start, int len) throws SAXException{
String str = new String (ch, start, len);

if (name){
System.out.println("Cust Name: "+str);
name = false;
}
if (id){
System.out.println("Cust ID: "+str);
id = false;
}
if (ccode){
System.out.println("Country Code: "+str);
ccode = false;
}
if (bcode){
System.out.println("Branch Code: "+str);
bcode = false;
}
if (ano){
System.out.println("AccountNbrs: "+str);
ano = false;
}

}
};
parser.parse(str, dHandler);
}
else{
System.out.println("File not found!");
}
}
catch (Exception e){

}
}
}

Thanks
