re.finditer issue, output is blank - anna - Feb-07-2019
Hi All,
trying below code, running with out error, however output is blank.
import re
from ciscoconfparse import CiscoConfParse
from ciscoconfparse.ccp_util import IPv4Obj
with open("conf.txt") as file:
data = file.read()
interface_ips = re.finditer(r"^(interface (?P<intf_name>.*)\n)"
r"( .*\n)*"
r"( ip address (?P<ipv4_address>\S+) (?P<subnet_mask>\S+))\n"
r"( description (?P<description>.*))\n",
data,re.MULTILINE)
for intf_ip in interface_ips:
print("%s %s/%s %s" % (intf_ip.group("intf_name"),
intf_ip.group("ipv4_address"),
intf_ip.group("subnet_mask"),
intf_ip.group("description")))below is my input file.interface Eth-Trunk1.120

In your regex, ip address comes before description, in the input file, it's the opposite.
Also, if this is a common file format, you might want to try looking up an existing parser instead of doing your own regex-based parsing.
