Element.findElement - confusion

Hello

I'm kind of confused on how to use Element.findElement.

I've something like this:

if (Event.findElement(event,'A')) {
   var elm = Event.findElement(event,'A');
   alert(elm.nodeName);
} else {
  alert('no link');
}

var elm = Event.findElement(event,'A');
   alert(elm.nodeName);

returns #document! since the Event.findElement is not a 'A' tag, why does it 
still goes through if condition and not the else stuff?

how could I do this so it would handle this properly.

thank you in advance for your help.
