Can you give a string that you would expect the regex to match and
what the expected result would be? Currently, it looks like the
interesting part of the regex (.|\s)*? would match any character of
any length once. There seems to be some redundancy that makes it more
confusing then it needs to be. I'm pretty sure that . will also match
anything that \s will match or maybe you just need to escape . because
you meant for it to be a literal.
