Any XML coders here?

Help! I need a gauge to automatically trigger the TAILHOOK animation above a certain speed. My own efforts have it constantly toggling. 
Aircraft is finished. A rather nifty compound helicopter that cruises at 235 knots. I'm using the tailhook to alter the rotor disk angle as I believe this is the ONLY thing left that will work on both FS2002 and FS9. I'm guessing the water rudder won't work at all, which is a shame as THAT doesn't put bl;oody silly messages on the screen while it's moving!
Thanks folks.
