[Pyparsing] ip address

[dikshie <di...@gm...>]

hi,
how to parse ipaddress from "irregular"log file?
for example my log file might be start with '***************'
or '***********start************' or '00000000000000'
and then follof by ip address.

i tried to use:

in_file = open(sys.argv[1], "r")
integer = Word( nums )
ipAddress = delimitedList( integer, ".", combine=True )
ip = ipAddress.parseString(line)
print ip

but fail

regards,

This will get any number of integers... even one. You want four specifically.

line? What's line? You're getting an un-helpful error here because you did a "from pyparsing import *". That's a bad plan. Never do an "import *".

Try this instead:

in_file = open(sys.argv[1], "r").read()
integer = Word( nums )
ipAddress = Combine(integer + "." + integer + "." + integer + "." + integer)
ip = ipAddress.searchString(in_file)
print ip
