Who would win... Xena or Wonder Woman?

Someone in a Xena group asked as to who would win in a fight between these two ladies.

Here's the thing.. I don't see them ever fighting against each other, unless it's as allies, they both fight for the greater good of mankind.
Neither would win because they would have nothing to fight about.

Xena is a lethal fighter so if a fight between the two did come to pass then Wonder Woman wouldn't stand a chance.
