[Bradley S. Huffman]

This subject sure does seem to come up alot, so I'll throw out my solution.

public static void sortContent(Element element, Comparator comparator) {
    // Get a List of the current children
    List contentList = element.getContent();

    // Temporarily remove all content
    element.setContent(null);           

    // All Elements, Text, Comments, etc. in contentList are now detached
    // from the parent element so it is safe to sort the list.
    Collections.sort(contentList, comparator);

    // Add the sorted content back
    element.setContent(contentList);
}
