Not really sure if I interpret this correctly. Is your protocol text or
binary? "Content-Length: \d+" seems to imply ASCII; if thats the case I guess
you can just do something along the line of:
>>> import re
>>> p = re.compile(r'^Content-Length: (\d+)')
>>> m = p.search("Content-Length: 123")
>>> int(m.group(1))
123
No?
If its a binary protocol, look at the struct module and the functions pack()
and unpack()
