function outputObj(o) {
    var txt = "",
        depth = 0;
    var sp = function(n) {
        var s = "";
        for (var i = 0; i < n; i++) {
            s += "&nbsp&nbsp&nbsp&nbsp&nbsp.";
        }
        return s;
    };
    var sub = function(obj) {
        var attr;
        for (attr in obj) {
            if ((typeof obj[attr]) !== "object") {
                txt += sp(depth) + "[attr:" + attr + " - depth:" + depth + " - value:<b>" +
                           obj[attr] + "</b>]<br>";
            } else {
                txt += sp(depth) + "[attr:" + attr + " - depth:" + depth + "]...<br>";
                depth++;
                arguments.callee(obj[attr]);
            }
        }
        depth--;
        return txt;
    };
    return sub(o);
