Read XML file into hashmap and create new object

Question

I am trying to read XML into a HashMap, I am trying to read each XML node and create new object based on its contents.

How do I retrieve the value of each node of the XML?

For example : I need to retrieve birthdate value within my for loop and use it to create a new studentInfo object.

xml :

<students xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:noNamespaceSchemaLocation="students.xsd"><description>A bunch students and courses</description><student studentID="0144085" gender ="M"><firstname>Jack</firstname>
  <lastname>Blogs</lastname> <birthday day="21" month="04" year="1983"/><paper>Data Structures and Algorithms</paper><paper>Distributed and Mobile Systems</paper>     <paper>Software Engineering</paper><paper>Highly Secure Systems</paper><paper>Engineering Computations</paper><paper>Object Oriented Programming</paper></student>

code :

                //jf : set StudentINfoSet class properties
            this.description =  rootXMLNode.getElementsByTagName( "description" ).item( 0 ).getTextContent();
            studentMap =  new HashMap<String, StudentInfo>();
            NodeList nodeList = document.getElementsByTagName( "student" );
            for (int i = 0; i < nodeList.getLength(); i++) {
                Node currentNode = nodeList.item(i);
                StudentInfo si = new StudentInfo(Integer.toString(i)){};
                /*
                 * String studentID, String firstName, String lastName,
        String birthdate, String gender, char studentGender
                 * */
                this.studentMap.put(Integer.toString(i), si);
            }
            System.out.println("Number of students : "+nodeList.getLength());

I would use JAXB, see example here http://www.mkyong.com/java/jaxb-hello-world-example/
