Character Description
| The alternation character (|) allows either expression on its side to match the
target string. The expression "a|b" will match ‘a’ as well as ‘b’.
. The dot (.) will match any character.
* The asterisk (*) indicates that the character to the left of the asterisk in the
expression should match 0 or more times.
+ The plus (+) is similar to the asterisk but there should be at least one match of
the character to the left of the + sign in the expression.
? The question mark (?) matches the character to its left 0 or 1 times.
[ ] Brackets ([ and ]) enclosing a set of characters indicates that any of the
enclosed characters may match the target character.
