    //get the node name and get the class name
    NodeList nodeList = document.getElementsByTagName("className");
    Node node = nodeList.item(0).getFirstChild();
    String className = node.getNodeValue();

    //return an object through the class name
    Class tempClass = Class.forName(className);
    Object object = tempClass.newInstance();
    return object;
