For parsing the XML, check out the API documentation for

org.w3c.dom.Document
javax.xml.parsers.DocumentBuilder
javax.xml.parsers.DocumentBuilderFactory

Then use XPath to find specific nodes in the document. See

javax.xml.xpath.XPathExpression
javax.xml.xpath.XPath
javax.xml.xpath.XPathFactory

If you have problems with any part, post again

Harold's free on-line book is loaded with examples. A bit old but still perfectly usable.

thank to Second Post...
is help a lot....
i can get the node that i want in xml
using xpath can get any node from different lvl of root....

share what i done

public class XPathAttribute {

    public static void main(String[] args)
            throws ParserConfigurationException, SAXException,
            IOException, XPathExpressionException {

        DocumentBuilderFactory domFactory =
                DocumentBuilderFactory.newInstance();
        domFactory.setNamespaceAware(true);
        DocumentBuilder builder = domFactory.newDocumentBuilder();
        Document doc = builder.parse("src/a.xml");
        XPath xpath = XPathFactory.newInstance().newXPath();
        XPathExpression expr =
                xpath.compile("//g/f/*/text()");
        Object result = expr.evaluate(doc, XPathConstants.NODESET);
        //for loop for expr
        NodeList nodes = (NodeList) result;
        for (int i = 0; i < nodes.getLength(); i++) {
            System.out.println(nodes.item(i).getNodeValue());
        }
    }
}
