Hi All guys!
i'm pretty new on regex, i have learned something by the way, but is still pour knowledge!
so i want ask you for clarification on how it work!
assuming i have the following strings, as you can see they can be formatted little different way one from another but they are very similar!
DTSTART;TZID="America/Chicago":20030819T000000
DTEND;TZID="America/Chicago":20030819T010000
DTSTART;TZID=US/Pacific
DTSTART;VALUE=DATE
now i want replace everything between the first A-Z block and the colon so for example i would keep
DTSTART:20030819T000000
DTEND:20030819T010000
DTSTART
DTSTART
so on my very noobs knowledge i have worked out this shitty regex! :-(
preg_replace( '/^[A-Z](?!;[A-Z]=[\w\W]+):$/m' , '' , $data );
but why i'm sure this regex will not work!? :-)
Pls help me!
PS: the title of question is pretty explaned, i want also know how for example use a well know string block for match another...
preg_replace( '/^[DTSTART](?!;[A-Z]=[\w\W]+):$/m' , '' , $data );
..without delete DTSTART
Thanks for the time!
