Remarks
Regular expression "^user"
matches a string begins with
"user", not "Auser".
Regular expression "user$"
matches a string ends with
"user", not "userA".
None
zo* can map to "z" and "zoo".
zo+ can map to "zo" and "zoo",
but not "z".
For example, "1-9" means
numbers from 1 to 9
(inclusive); "a-h" means from a
to h (inclusive).
For example, [1-36A] can
match only one character
among 1, 2, 3, 6, and A.
For example, (123A) means a
string "123A"; "408(12)+" can
match 40812 or 408121212.
But it cannot match 408. That
is, "12" can appear
continuously and it must at
least appear once.
