I've got a file full of log and I'm trying to extract some data from those log, a log look like:
IP_adress - - [Date_time] "method" response_nb time "page" "UA" "IP_adress"
I want to extract the IP_adress and UA. Is using a regex a good idea to extract data from those log or is there some other way to do it properly?
Just split the string and get last two elements.
>>>
>>> str = 'IP_adress - - [Date_time] "method" response_nb time "page" "UA" "IP_a
dress"'
>>> tmp_list = str.split()
>>>
>>> tmp_list
['IP_adress', '-', '-', '[Date_time]', '"method"', 'response_nb', 'time', '"page
"', '"UA"', '"IP_adress"']
>>> tmp_list[-1]
'"IP_adress"'
>>> tmp_list[-2]
'"UA"'
>>>
If first IP Adress is required...
>>> tmp_list[0]
'IP_adress'
>>>
Replace double quotes as below from last IP Adress.
>>>
>>> tmp_list[-1].replace('"','')
'IP_adress'
>>>
