regex - Extract a specific word from string in PostgreSQL -

-

i using pgadmin version 1.16.1 , need extract words 'login' , 'logout' result column

url  "http:/login-v1.abcd.com/service/abc/integration"  "http:/xxxxxxxxlogout" "https:/login-v1.abcd.com/service"

result

 url                                                 action    "http:/login-v1.abcd.com/service/abc/integration"    login   "http:/xxxxxxxxlogout"                              logout "https:/login-v1.abcd.com/service"                   login

how can this?

use substring() regular expression:

with t(txt) (values       ('http:/login-v1.abcd.com/service/abc/integration')     ,('http:/xxxxxxxxlogout')     ,('https:/login-v1.abcd.com/service')     ) select txt, substring(txt '(login|logout)') action t
