XOM API for Processing XML with Java

[Wolfgang Hoschek <whoschek AT lbl.gov>]

Not that it's a significant problem, but I'd transform recursions into 
iterations when doing so is obvious and clarity does not suffer:

nu.xom.Element

        private static boolean isAncestor(Node parent, Node child) {
                while (true) {
                        if (child == parent) return true;
                        if (parent == null) return false;
                        parent = parent.getParent();
                }
        }

instead of:

        private static boolean isAncestor(Node parent, Node child) {
                if (child == parent) return true;
                if (parent == null) return false;
                else return isAncestor(parent.getParent(), child);
        }

(No need to hope that hotspot would some intelligent magic)
