> As of now groovy supports clone node feature without cloning parents.
> We can add following custom methods in some util class to make cloning more advanced :
> 1:
> {code}
> private Node cloneNode(Node node, Node parentNode) {
>     Object newValue = node.value()
>     Node clonedNode = new Node(null, node.name(), new HashMap(node.attributes()), newValue)
>     if (newValue instanceof NodeList) {
>         NodeList nodes = (NodeList) newValue
>         newValue = cloneNodeList(nodes, clonedNode)
>     }
>     clonedNode.setValue(newValue)
>     clonedNode.setParent(parentNode)
>     return clonedNode
> }
> {code}
> 2:
> {code}
> private NodeList cloneNodeList(NodeList nodeList, Node parentNode) {
>     NodeList result = new NodeList(nodeList.size())
>     for (int i = 0; i < nodeList.size(); i++) {
>         Object next = nodeList.get(i)
>         if (next instanceof Node) {
>             result.add(cloneNode((Node) next, parentNode))
>         } else {
>             result.add(next)
>         }
>     }
>     return result
> }
> {code}
