regex - JQuery change all elements text

Question

I need jquery to change numbers in all of pages. for example i want change 1 to ? so i tried this way:

$("*").each(function(){
    $(this).html(  $(this).html().replace(1,"?")  );
})

but this will change css rules and attributes also. is there any trick to escape css and attributes?

This isn't a job that jQuery naturally fits into. Instead of getting jQuery to fetch a flat list of all elements, recursively traverse through the DOM tree yourself, searching for text nodes to perform the replace on.

function recursiveReplace(node) {
    if (node.nodeType === Node.TEXT_NODE) {
        node.nodeValue = node.nodeValue.replace("1", "?");
    } else if (node.nodeType == Node.ELEMENT_NODE) {
        $(node).contents().each(function () {
            recursiveReplace(this);
        });
    }
}

recursiveReplace(document.body);
