Subject: (Maybe) a simple question about regex

Hello!

I think that I am missing a very simple concept about regex.

s = '0123456789'
s.scan(/\d\d/) #-> ["01", "23", "45", "67", "89"]

Now I want to exclude "45".
How can I express it in the regex?
When it's only one character, I can use ^.
But for 2 characters, I don't think I can use it.

What I want is:

s = '0123456789'
s.scan(some_regex) #-> ["01", "23", "67", "89"]

What should some_regex be?

Can somebody help me?

Sam
