Readline and record separator

[Johny]

Is it possible to change record separator when using readline?
As far as I know readline reads characters until found '\n' and it is
the end of record for readline.
My problem is that my record consits several '\n' and when I use
readline it does NOT read the whole my record.
So If I could change '\n' as  a record separator for readline, it
would solve my problem.
Any idea?
Thank you
