Remove all child nodes of a node

Question

I have a node of DOM document. How can I remove all of its child nodes? For example:

<employee> 
     <one/>
     <two/>
     <three/>
 </employee>

Becomes:

   <employee>
   </employee>

I want to remove all child nodes of employee.

Answer 1

No need to remove child nodes of child nodes

public static void removeChilds(Node node) {
    while (node.hasChildNodes())
        node.removeChild(node.getFirstChild());
}

Answer 2

Just use:

Node result = node.cloneNode(false);

As document:

Node cloneNode(boolean deep)
deep - If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).
