Extract 65-char string between forward slashes?

[pcorchary]

I've been trying to extract a field 'user_id' from lines like below. The field will always be 65 char long alphanumeric and usually be between forward slashes. (there is one case where it is in single quotes with text before and after.) I dont think there are any other 65-char strings to generate false positives.

This ...

(?P<FIELDNAME>\/[a-z0-9A-Z]{65}\/) 

isn't getting it ... can some REX guru tell me what I'm doing wrong, please? 🙂

Try this reg ex:

\[\/(?<field>\w{64})\/

small update on the regex, this will not include the \/ in the value of field:

(?\w{64})
