yeah... you are right guys. I have matched two problems
reg exp are innocents .

Ok. Let's say so:
I have to read each line of a file and strip a particular string from there
(a string containing octal notation too)

the problem is actually the file.readline() that doesn't return
what I was expected to.

pardon my 'newbyeeeee'  but is there a way to read a  line xy from that file
and obtaining:

line xy:       \006\034abc

('\x06\x1cabc',)

 and not every single char in it like now ?
('\\006\\034abc\n',)

(before I start to reinvent the wheel ....... :)  )

Thank you
