Subject: Problem with getting RegEx to work

All,

I'm a novice when it comes to Ruby so I'm hoping that one of you guys
can explain the following to me.

The following line works as I expected it to and prints "This is a
test" with one word per line:
" -XThis -Xis -Xa -Xtest ".scan( /-X(.*?)\s/ ) { |x| puts x }


However this line only prints 4 lines of empty text:
" -XThis -Xis -Xa -Xtest ".scan( /\s-X(.*?)/ ) { |x| puts x }

Can someone explain this to me?
Thanks.
