XML - SAX Parsing Question

Question

Hi,
I am parsing XML using SAX parser and fill the values into the HashTable ( like Key value pair ).. so i can get the vaues for a particular key using hash get function.
For the following XML. There are 2 "subscriberNumber" attribute, one is under "sn:Subscriber" and the another is under "sn:SubscriberChange".
I can able to put this values in hash table and when i print the Hash table it is printing as sn:subscriberNumber=[1234567890, 1234567890] .. But how will i know which one is from "sn:Subscriber" and which is from "sn:SubscriberChange"
This is the XML :
<sn:SubscriberNotification>
<sn:notificationSubType>1120</sn:notificationSubType>
<sn:Subscriber>
     <cng:PaymentType>PostPaid</cng:PaymentType>
     <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:Subscriber>
<sn:SubscriberChange>
     <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:SubscriberChange>
</sn:SubscriberNotification>
Any suggestion and pointers are really helpful
Thanks,

Try something like this:
import java.util.Stack;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
class MyHandler extends DefaultHandler {
    Stack openTags = new Stack();
    public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
        if (qName.equals("sn:subscriberNumber")) {
            String parentTag = (String)openTags.peek();
            System.out.println("Parent tag of this <sn:subscriberNumber> is : <" + parentTag + ">");
        openTags.push(qName);
    public void endElement(String uri, String localName, String qName) throws SAXException {
        openTags.pop();
}Regards
