jQuery is starting to be really enjoyable. This is an easy peasy way to make your own custom selector, which could be used to extract elements in a cleaner way. This also allows you to find any type of element based on one or more attributes which you couldn´t use the included selectors to find.
$.expr[':'].my_elements = function(obj){
var $this = $(obj);
return ($this.attr('special_attribute') != '');
};
Use the selector as usual:
$('h1:my_elements').css({color: "green"});
