jquery find and replace text, without element id

Question

I'm playing around with finding and replacing text.

The only problem I'm having is finding a text string, that is not attached to an element with an ID. Otherwise, it would be easy.

I'm trying something like this:

$("*").each(function () {
    $(this).html(this.html().replace('Original Text','New Text'));
});

Not working too well.
Anyone run into this before?

Also, if I have several words or phrases to find and replace, how does that affect the speed/processing power of the user's browser? Is it a memory hog?

Answer 1

$("*").contents().each(function() {
    if(this.nodeType == 3)
        this.nodeValue = this.nodeValue.replace("old", "new");
});
