Remove empty list item with jquery

I have a list which is dynamically built, but there are empty list items which need removing.

<ul>
<li>www</li>
<li>www</li>
<li>www</li>
<li></li>
<li></li>
<li></li>
</ul>

How do I开发者_如何学运维 do this with JQuery?

---

$('ul li:empty').remove();

---

$('ul li').filter(function() {return $(this).text()​​​​​​​ == '';}).remove();​

---

$('ul').find('li').each(function(){
    if($(this).is(':empty'))
        $(this).remove();
});

Please use Andy's implementation (above mine :))
