var ie = function(v, p, needle, undef) {
 
needle = p.getElementsByTagName('br');
 
while(
p.innerHTML = '<!--[if gt IE ' + (++v) + ']><br><![endif]-->',
needle[0]
);
 
return v > 4 ? v : undef;
 
}(3, document.createElement('p'));

(you'll need to test p.getElementsByTagName('br')[0] in the while loop)

@cowboy: needle is live nodelist, don't need to re get in loop

How did I not know that? That's really interesting, thanks!
