JAXB unmarshal list element by element

I need some help with unmarshalling some XML. Especially with unmarshalling a list of elements. See the following example:

@XmlRootElement(name="element")
public class Element
{
    private ArrayList<Element> children;

    public ArrayList<Element> getChildren() {
        return children;
    }

    @XmlElementWrapper(name = "children")
    @XmlElement(name = "element")
    public void setChildren(ArrayList<Element> children) {
        this.children = children;
    }
}

This will unmarshal the list perfectly, BUT what I need is an unmarshalling of all children element by element and adding them through some "addElement" method:

    public void addElement(Element element) {
        children.add(element)
    }

Is this possible with some simple annotation magic? Of course I could loop through the elements and call "addElement".
