arborescent xml

I have a xml tree that I want to browse

<?xml version="1.0" encoding="UTF-8"?>
<Ontology name="Ontology">
<DecisionMaker name="SalesManager">
<BusinessProcess name="Order" />
</DecisionMaker>
</Ontology>
but with this code

Code:

---

            List le=racine.getChildren();
            ListIterator le1=le.listIterator();
            while(le1.hasNext())
            {
                Element f=(Element) le1.next();
                System.out.println("f"+f.getName());
                String name=f.getAttributeValue("name");
                System.out.println("name"+name);
            }

---

I can not access to some nodes such "BusinessProcess" in this example
and i have as result:
fDecisionMaker
nSalesManager

when i added to my code after "System.out.println("name"+name);"

Code:

---

List h=f.getChildren();
ListIterator a1=h.listIterator(); 
while(a1.hasNext())
        {
            Element e=(Element) a1.next();
            le1.add(e);
        }

i have this error "The Content already has an existing parent "DecisionMaker""
i don't know what i do?please help me

That doesn't surprise me: the top level node (Ontology) has one child node (DecisionMaker) which has one child itself (BusinessProcess). Your iterator traverses the children of the top level node only. An Element extends a Node and a Node has a getChildNodes() method; try that on your DecisionMaker node ...

kind regards,

thanks
but i don't have this method "getChildNodes()" when i made

Code:

---

f.getChildNodes();

---

i hade error of unexistion method

I find that strange because an Element (an interface) extends the interface Node and getChildNodes() is defined in the Node interface ...

my problem is to browse all nodes in this arborescent and to read or to add other nodes
so how???
