AS3 refer to other movieclips from a movieclip

[Forbiden Chaos]

I have two movieclips on the stage... man and enemies, inside man there is a movieclip called sword, inside enemies there is a movieclip called enemy then inside that a movieclip called float.

stage -> man -> sword
stage -> enemies -> enemy -> float

Is there anyway I can refer to sword from within enemy?
the code would be for a hitTest like:

if (float.hitTestObject("way to refer to sword"))==true{
         nextFrame();
}
