Answer 1

myString = $('<div />').html(myString).find('div').replaceWith(function() {
    var p = $('<p />');
    p.html($(this).html());
    $.each(this.attributes, function(index, attr) {
        p.attr(attr.name, attr.value);  
    });
    return p;
}).end().html();

Javascript with regular expression:

myString = myString.replace(/<(\/)?div[^>]*>/g, '<$1p>');

Also see my jsfiddle .

=== UPDATE ===

myString = myString.replace(/<(\/)?div([^>]*)>/g, '<$1p$2>');

Answer 3

Trying something with jQuery, however, I am not sure if it is any better than what alex suggested.

var $replaceString=$(replaceString);

$("div",$replaceString).each(
    function()
    {
        var $p=$(document.createElement('p')).html($(this).html());
        //add code to add any attribute that you want to be copied over.
        $(this).after($p);
        $(this).remove();
    }
);
