parsing an nmap result

I'm working on a project with Python 2.6 on linux and I am using nmap from the terminal to get those scan result, I get this inside a string:

Starting Nmap 6.47 ( http://nmap.org ) at 2015-06-28 23:15 IDT

Nmap scan report for 10.0.0.4

Too many fingerprints match this host to give specific OS details
Network Distance: 0 hops

OS detection performed. Please report any incorrect results at http://nmap.org/submit/ .
Nmap done: 50 IP addresses (4 hosts up) scanned in 56.74 second

I want to parse it into something like this: (example of the first block)

['10.0.0.5', [['62078/tcp', 'open', 'iphone-sync']], '70:3E:AC:22:A0:B0', 'Apple Mac OS X 10.7.0 (Lion) - 10.9.2 (Mavericks) or iOS 4.1 - 7.1 (Darwin 10.0.0 - 14.0.0)']

this is the pattern I want [IP, [list of [port, state, service], MAC, OS] Is there an easy way to do that with Python?

Have you looked at the following Python modules?

  • python-nmap: This is a python class to use nmap and access scan results from python3
  • python-libnmap: Python NMAP library enabling you to start async nmap tasks, parse and compare/diff scan results

In particular, python-nmap is exactly what you want to do.

python-nmap usage example:

>>> import nmap
>>> nm = nmap.PortScanner()
>>> nm.scan('127.0.0.1', '22-443')
>>> nm.command_line()
'nmap -oX - -p 22-443 -sV 127.0.0.1'
>>> nm.scaninfo()
{'tcp': {'services': '22-443', 'method': 'connect'}}
>>> nm.all_hosts()
['127.0.0.1']
>>> nm['127.0.0.1'].hostname()
'localhost'
>>> nm['127.0.0.1'].state()
'up'
>>> nm['127.0.0.1'].all_protocols()
['tcp']
>>> nm['127.0.0.1']['tcp'].keys()
[80, 25, 443, 22, 111]
>>> nm['127.0.0.1'].has_tcp(22)
True
>>> nm['127.0.0.1'].has_tcp(23)
False
>>> nm['127.0.0.1']['tcp'][22]
{'state': 'open', 'reason': 'syn-ack', 'name': 'ssh'}
>>> nm['127.0.0.1'].tcp(22)
{'state': 'open', 'reason': 'syn-ack', 'name': 'ssh'}
>>> nm['127.0.0.1']['tcp'][22]['state']
'open'

>>> for host in nm.all_hosts():
>>>     print('----------------------------------------------------')
>>>     print('Host : %s (%s)' % (host, nm[host].hostname()))
>>>     print('State : %s' % nm[host].state())
>>>     for proto in nm[host].all_protocols():
>>>         print('----------')
>>>         print('Protocol : %s' % proto)
>>> 
>>>         lport = nm[host][proto].keys()
>>>         lport.sort()
>>>         for port in lport:
>>>             print ('port : %s\tstate : %s' % (port, nm[host][proto][port]['state']))
