XML and Tree Model !!!

Question

I am wanting to implement the tree model from xml data.
I am new to this so would appreicate any help filling in the gaps. My aim is to reflect this xml file in a JTreeTable format (I have left out the table model implementation.)
A sample xml file looks like this :
<?xml version="1.0" ?>
<exam>
<Column class="xTableModel">Attribute</Column>
<Column class="String">Value</Column>

<Id>1</Id>

</Question>

How I am Reading the file:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder parser = factory.newDocumentBuilder();
doc = parser.parse(xmlfile);
Tree Model Methods. //Not really sure what i am doing here.
public Object getChild(Object node, int i)
Node parent = ((Node) node);
Object child = parent.getChildNodes().item(i);
return child;
public int getChildCount(Object node)
Node parent = ((Node) node);
// int child = parent.getChildNodes().getLength();
return 1;
public boolean isleaf(Object node)
Node parent = ((Node)node);
Node child = parent.getFirstChild();
return (child == null);
}

you can use a adapter pattern to convert the xml element to a TreeModel, this can be used by JTree
