update an xml file with jaxb and accessing to its elements

HI

I am working with jaxb .I has get my java classes from my schema xml .
My root element is binded to a java classs with getters and setters for its attributes and a method that returns a list of the other elements .

Code:

public List<Object> getContent() {
        if (content == null) {
            content = new ArrayList<Object>();
        }
        return this.content;
    }

I have an xml file that contains just the basic elements and i want to insert elemets and values of attributes .I succed to add attributes to my root element but how can i acceed by this method to other elements and use its methods? IDE:   Netbeans 6.5.1 Technology:  jaxb

jaxb/unmarshall-from-xml-using-jaxb-t5294.html
jaxb/marshal-java-object-to-xml-file-t5293.html

My problem that that the method getContent return different objects which are nodes .
I can just access to the root by :

Code:

root =(root)u.unmarshal(new FileInputStream("A.xml")

i want to access to the methods of the binded nodes .

When i access to the first node(E) just after the root and i want to display the name of the it first subnode with this code

Code:

System.out.println(E.getContent();.get(0).getClass().getName());

I get in output this:

javax.xml.bind.JAXBElement


Please i need an urgent help

am just wondering . we don't you try to do the following :

Code:

System.out.println(E.getContent().get(0).getClass().getName());


did u tried to do the following

Code:

System.out.println(E.getContent().getClass().getName());


i HAVE RESOLVED tHE PROBLEM :

List Li=E.getContent();
JAXBElement D=(JAXBElement)Li.get(0);//it returns jaxb
NOEUD Da=( NOEUD)D.getValue();

thanks a lot
