How can I return data (string array) from the SAXParser handler?

Question

With the below code I want to return a array of data back from the SAX parser for each data inside the nodes. I have a array list which will keep the data under each leaf node. How do I use this data outside the handler or return it? -

public class ReadXMLFile {

   public static xmldataparser(String argv[]) {

    try {

    SAXParserFactory factory = SAXParserFactory.newInstance();
    SAXParser saxParser = factory.newSAXParser();

    DefaultHandler handler = new DefaultHandler() {

    boolean burl = false;
    boolean bip = false;
    List<String> a = new ArrayList<String>();

    public void startElement(String uri, String localName,String qName, 
                Attributes attributes) throws SAXException {

        System.out.println("Start Element :" + qName);

        if (qName.equalsIgnoreCase("URL")) {
            burl = true;
        }

        if (qName.equalsIgnoreCase("IP")) {
            bip = true;
        }



    }

    public void endElement(String uri, String localName,
        String qName) throws SAXException {

        System.out.println("End Element :" + qName);

    }

    public void characters(char ch[], int start, int length) throws SAXException {

        if (burl) {
            System.out.println("URL : " + new String(ch, start, length));
            a.add(new String(ch, start, length));
            burl = false;
        }

        if (bip) {
            System.out.println("IP : " + new String(ch, start, length));
            bip = false;
            a.add(new String(ch, start, length));
        }


    }

     };
  }
return <the array from the handler(this is where I need help)>
 }
}

If you make the variables that store your result (e.g. a in this case) public or create a getter method for them, you will be able to access them and use any information stored there in code outside of the handler class.

Create another class and extends DefaultHandler. Create method in handler class(ex:-sample). Before calling SAXParser.parse(filename,handler) make a call sample method. Create list as a global variable. You can add the required values to the list. Finally return the list from the sample method.
