Answer 1

wrap it in a plugin

(function($) {   
    $.fn.tagRemover = function() {           
        return this.each(function() {            
        var $this = $(this);
        var text = $this.text();
        $this.replaceWith(text);            
        });            
    }    
})(jQuery);

and then use like so

$('div span').tagRemover();
