****edit****

ok the glove has been thrown down…

var elements = (document.getElementsByTagName('li'));
var vals = [];
for(var i=0;typeof(elements[i])!='undefined';vals.push(elements[i++].getAttribute('value')));

no library 3 lines of code…

epicly faster

---

var myVals = [];
$('li','ul').each(function(){
  myVals.push($(this).attr('value'));
});

and using jquery’s map function…

var myVals = [];
$('li','ul').map(function(){
  myVals.push($(this).attr('value'));
});

and they are both equally as fast..
