Can I iterate through a NodeList using for-each in Java?

Question

I want to iterate through a NodeList using a for-each loop in Java. I have it working with a for loop and a do-while loop but not for-each.

Node

The validated solution is very useful, but here I share an improved solution based on the valid one, this helps you iterate as well, but easy to use, and secure:

public class XMLHelper {
    private XMLHelper() { }

    public static List getChildNodes(NodeList l) {
        List children = Collections.emptyList();
        if (l != null && l.getLength() > 0) {
            if (l.item(0) != null && l.item(0).hasChildNodes()) {
                children = new NodeListWrapper(l.item(0).getChildNodes());
            }
        }
        return children;
    }

    public static List getChildNodes(Node n) {
        List children = Collections.emptyList();
        if (n != null && n.hasChildNodes()) {
            NodeList l = n.getChildNodes();
            if (l != null && l.getLength() > 0) {
                children = new NodeListWrapper(l);
            }
        }
        return children;
    }

    private static final class NodeListWrapper extends AbstractList implements RandomAccess {
        private final NodeList list;
        NodeListWrapper(NodeList l) {
            list = l;
        }
        public Node get(int index) {
            return list.item(index);
        }
        public int size() {
            return list.getLength();
        }
    }

}

Usage:

 for (Node inner : XMLHelper.getChildNodes(node)) { ... }
