The first step is to simplify the problem. Don't worry so much about
all of the optional stuff, look at the possibilities and see what they
have in common. Then you can write an expression that will match the
common bits and skip over the optional bits.
There have been two or three examples posted that will work. Pick one
and give it a try.
