Javascript Replace All words

I need to replace all the words in a DOM (web page in memory) using jquery and javascript. I need to transform this:

<html>
<head>
    Hi to all
</head>
<body>
    Hi to all
</body>
</html>

Into this: 

<html>
    <head>
        Bye to all
    </head>
    <body>
        Bye to all
    </body>
</html>

But without modifying the tags (ONLY THE VALUES IN THERE)

One try is:

jQuery.fn.replaceEachOne = function (objective, rep) {
    return this.each( function(){
                $(this).html( $(this).html().replace( new RegExp('(\\s'+objective+'\\s(?![[\\w\\s?&.\\/;#~%"=-]*>]))', "ig"), rep) );
            }
        );
}

But it continue replacing the tag values and breaks the page if I put it.

Help!!!

Finally...

Thanks to everyone...

jQuery.fn.replaceEachOne = function (objective, reposition) {
    this.contents().each(function(){
        if (this.nodeType == Node.ELEMENT_NODE) {
            $(this).replaceEachOne(objective, reposition);
        } else if (this.nodeType == Node.TEXT_NODE) {
            var label = document.createElement("label");
            label.innerHTML = this.nodeValue.replace(objective, reposition);
            this.parentNode.insertBefore(label, this);
            this.parentNode.removeChild(this);
        }
    }); 
}

if you don't want it to change your tags, why do you modify the "html"and not just the text?

jQuery.fn.replaceEachOne = function (objective, rep) {
    return this.each( function(){
                $(this).text( $(this).text().replace( new RegExp('(\\s'+objective+'\\s(?![[\\w\\s?&.\\/;#~%"=-]*>]))', "ig"), rep) );
            }
        );
}

One way that would do it albeit inefficiently would be:

var element = document.getElementsByTagName('html')[0];
element.innerHTML = element.innerHTML.replace('Hi to all', 'Bye to all');

The 'Hi to all' in quotes can also be replaced with a regex if you want.

Im guessing that there are going to be other elements in the header rather then just replacing everything with the new text. Try out something like this

$(function(){
  var element = $('body, head').find('*:contains("Hi to all")');
  element.html('Bye to all');
});
