javascript - Is there any onDocumentChange event?

Is there any event in Internet Explorer, that is fired whenever DOM is changed? For example:

document.attachEvent("ondocumentchange", function () {
    alert("you've just changed DOM!");
});

And when I execute:

document.appendChild(document.createElement("img"));

Window with text "you've just changed DOM!" appears.

I try to emulate "advanced" CSS selectors (e.g. +, >, [attr]) in IE6 using Javascript. However to work properly with dynamic content, they would have to be recalculated after each change in document.

Brute-force "solution":

(function (previousInnerHTML) {
    return function () {
        if (document.body.innerHTML !== previousInnerHTML) {
            alert("you've just (at max 33ms ago) changed DOM");
        }
        setTimout(arguments.callee, 33);
    };
})(document.body.innerHTML)();
