Sort a set of li tags alphanumerically

Question

I\'ve been playing around trying to get a function that will sort a selection of li tags by their content but currently to no avail (at least no speed/accuracy);

Answer 1

var sortList = function () {
    var ul = document.getElementsByTagName("ul"),
    ol = document.getElementsByTagName("ol"),
    sort = function (x) {
        var a, li;
        for (a = 0; a < x.length; a += 1) {
            li = x[a].getElementsByTagName("li");
            li = li.sort();
            x[a].innerHTML = li.join("");
        }
    };
    sort(ul);
    sort(ol);
};
