Answer 1

What about this: (js fiddle demo)

var StripTags = function (desiredClass)
{
    var nodes = document.querySelectorAll('.' + desiredClass);
    for (var i = 0; i < nodes.length; i++)
        nodes[i].parentNode.removeChild(nodes[i]);
}

StripTags("tooltip_left");
StripTags("tooltip_right");
StripTags("tooltip_bottom");
