Subject: Re: Use the characters "+" and "-" in regular expressions
Is there a way to use the character "+" and "-" in regular
expressions?
Yes, use character sets, e.g. [+] and [-]. If more characters are in a
set along with a hyphen, that hyphen needs to be the first element of
the set so as not to be interpreted as defining a range of characters.
So, the character set containing 0, 9 and hyphen is [-09] or [-90], not
[0-9], which would include all digits between 0 and 9, but not the
hyphen.
