i have used below code:
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {

tempVal = "";
if (qName.equalsIgnoreCase("Category")) {
// create a new instance of Laptop
laptop = new Laptop();
laptop.setBrand(attributes.getValue("name"));
}
else if (qName.equalsIgnoreCase("article")) {

Use handler for startElement and endElement both of them. I suggest you use Stack as member of parser.
private tagStack = new Stack();
public void startElement(String uri, String localName, String qName,
Attributes attributes) {
...
else if (qName.equals("image")) {
if ("thumb_image".equals(tagStack.peek())) {
image = new Laptop();
image.setImageURL(attributes.getValue("url"));
}
}
// make sure it is at the end of method
tagStack.push(qName);
}
public void endElement(String uri, String localName, String qName) {
...
tagStack.pop();
}
If you want only thumb image and nothing more nested, you may set bool in_thumb_image to true from startElement() and false from endElement() if it is qName=="thumb_image". Stack is more generic. For higher levels, you may use tagStack.search();
And off topic. XML is case sensitive, ignoreCase should not be used in my opinion.
