Getting web data into file

By script I need to go to “vpnbook.com” and open the “Openvpn” tab
On that page I need to get the “username:vpnbook” and the next line “password:???”
I need to put those two into line one and two of a file “pwfile”

When I have those I need to execute openVPN with the --auth-user-pass [up] userpassword option so that it sets up automatically

--auth-user-pass [up] : Authenticate with server using username/password.
up is a file containing username/pass

Thanks for any pointers.

I can also get that data from the below site without a TAB needed I see
