The markup contains so many duplicated ID so, it is not a valid Markup. Instead I suggest you to remove the duplicate element, thus having a unique element on an array.
Here is a snippet for this purpose.
var list = {};
$('li').each(function() {
var id = $(this).attr('id');
if (list[id])
$(this).remove();
else
list[id] = $(this);
});
