Log Parsing with Regex

Question

I\'m trying to parse an Apache Log with regex using Python and assign it to separate variables.

ACCESS_LOG_PATTERN = \'^(\\S+) (\\S+) (\\S+) \\[([\\w:/]+\\s[         


        

Answer 1

You need to make your group 7 optional by adding a ?. Use the following regex:

^(\S+) (\S+) (\S+) \[([\w:/]+\s[+\-]\d{4})\] "(\S+) (\S+)\s*(\S+)?\s*" (\d{3}) (\S+)
                                                                 ↑
