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.

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).

public static void removeAllChildren(Node node) {
    NodeList nodeList = node.getChildNodes();
    int i = 0;
    do {
        Node item = nodeList.item(i);
        if (item.hasChildNodes()) {
            removeAllChildren(item);
            i--;
        }
        node.removeChild(item);
        i++;
    } while (i < nodeList.getLength());
}
