[lug] Regex Help

[Chris McDermott]

You could try this:

/https?:\/\/[^\/]+\/specificpath/


https?:\/\/ - this will match either "http://" or "https://"
[^\/]+ - this will match anything *except* a "/" character



It worked for at least some preliminary testing:

[chris at bull sandbox]$ ./test.pl http://www.example.com/specificpath
Yay!
[chris at bull sandbox]$ ./test.pl https://www.example.com/specificpath
Yay!
[chris at bull sandbox]$ ./test.pl https://192.158.282.12/specificpath

Yay!
[chris at bull sandbox]$ ./test.pl https://192.158.282.12/blah/specificpath
Boo!
[chris at bull sandbox]$ ./test.pl
https://192.158.282.12/blah/balh/specificpath
Boo!
[chris at bull sandbox]$ ./test.pl
https://www.cnn.com/blah/balh/specificpath

Boo!
