Hi, I'm trying to extract a num from a string. This string is in fact
some number of headers separated by \r\n or \n. for now I just need to
extract the value of "Content-Length" (case insensitive) header.

Why don't you use Net::Http? IIRC this gives you individual header
fields already.

For example:

irb> headers =3D "Via: via1,via2,\r\n via3\r\nFrom:
from_user@domain\nContent-length: 22\r\nTo: to_user@domain\n"

I do the following:

irb> headers.scan(/content-length\s*:\s*([0-9]*)/i).to_s.to_i
=3D> 22

In case the "Content-Length" header exist but has empty value I get 0
with the above code (that's what I need in fact).

Is there any way faster to do the same? any help?

headers[/content-length:\s*(\d+)/i, 1].to_i

Cheers

robert
