I have situation where in the regular expression is something like this:
^b?A+b?$
So b may match at the start of the string 0 or 1 times, and A must match one or more times. Again b may match at the end of the string 0 or 1 times.
Now I want to modify this regular expression in such way that it may match b either at the start or at the end of the string, but not both.
How do I do this?
Theres a nice “or” operator in regexps you can use.
