Really? Using a little XOM code as an example, I find

    for (int i = 0; i < element.getChildCount(); i++) {
        Node child = element.getChild(i);
        if (child instanceof Element) {

just as easy as

    Elements children = element.getChildElements();
    for (int i = 0; i < children.size(); i++) {

And is getChildElements("bar") in JDOM and XOM really more convenient
that dom4j Node.selectNodes("child::bar")? It isn't as powerfull. Is it
faster? Maybe/maybe not. Will that still be true next year? Agian maybe/maybe

But again, this late in the game, this is all just a mental exercise.
