从字符串中提取同一匹配项的多个实例

Question

I need to extract the value of all instances of pattern match of ssid in a string.

interface_info = '''Interface wlan1-cabin-2  
                ifindex 37  
                wdev 0x300000003  
                addr 06:53:1a:4e:07:02  
                ssid SSID3  
                type AP  
                channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz  
        Interface wlan1-cabin-1  
                ifindex 36  
                wdev 0x300000002  
                addr 06:53:1a:4e:07:01  
                ssid SSIDTEST2  
                type AP  
                channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz  
        Interface wlan1  
                ifindex 7
                wdev 0x300000001  
                addr 06:53:1a:4e:07:00  
                ssid SSID1 
                type AP  
                channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz  '''

ssid_regex = re.compile('ssid (\w+)')              
ssid_extract = re.search(ssid_regex,interface_info)

print (ssid_extract)

returns a value for first match only. I need to extract the value of every ssid match [SSID3, SSIDTEST2, SSID1}. SSID3

Actual SSID3
expected [SSID3, SSIDTEST2, SSID1]

!/usr/bin/env python

import re interface_info = '''
phy#3
Interface wlan1-cabin-1
ifindex 36
wdev 0x300000002
addr 06:53:1a:4e:07:01
ssid SSIDTEST3
type AP
channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz
Interface wlan1
ifindex 7
wdev 0x300000001
addr 06:53:1a:4e:07:00
ssid SSIDTEST2
type AP
channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz
phy#2
Interface wlan0
ifindex 6
wdev 0x200000001
addr 02:ac:1a:4e:07:00
ssid SSID1
type AP
channel 149 (5745 MHz), width: 80 MHz, center1: 5775 MHz

''' interface_info = re.sub(re.compile('^\\s+', re.MULTILINE), '', interface_info) ssid_regex = re.compile('ssid (\\w+)') ssid_extract = re.findall(ssid_regex, interface_info[interface_info.index("Interface wlan1"):])

print (ssid_extract) print (type(ssid_extract))

print(str(interface_info))
