* getElementsByTagName
The getElementsByTagName() method accesses all elements with the specified tagname.

var vals = [];
// Populate the array
for(var i = 0, l = lis.length; i < l; i++)
vals.push(lis[i].innerHTML);
// Sort it
vals.sort();
// Sometimes you gotta DESC
if(sortDescending)
vals.reverse();
// Change the list on the page
for(var i = 0, l = lis.length; i < l; i++)
lis[i].innerHTML = vals[i];
}
