deciphering a regular expression
Posted on 2012-03-30
Sorry for the simple question, but I'm not familiar with regular expressions.
Does the following regex [0-9][A-Za-z][0-9][A-Za-z] mean the following:
The first character has to be a number 0-9 then the next character has to be a-z (uppercase or lowercase) then the next character has to be a number 0-9 and then finally the last character must be a-z (uppercase or lowercase)?
Is that correct?
