Using regex to extract a string including a space between other strings and whitespace-CodePudding

I have the following output from my wireless controller and also the regex statement below. I am trying to parse out the various values using regex named capturing groups. The space in the 'Global/whatever Lab/Lab01' value is throwing everything after that value off. Is there a way to repalce the \S after the group to capture the whole value of 'Global/whatever Lab/Lab01'? Thank you.

CodePudding user response：

maybe try doing something similar to replacing \S with [\S ] I don't know if there's anything like an escape code you can use to represent the space between the []

CodePudding user response：

When you need to match a multi-word field value, make sure you can describe the format of the field(s) next to it. Once you know the rules, you can match the "unknown" field with a mere .*? pattern.

See an example solution:

(?P<ap_name>\S )\s (?P<slots>\d )\s (?P<model_number>\S )\s (?P<ether_mac>\S )\s (?P<radio_mac>\S )\s (?P<location>.*?)\s (?P<country>[A-Z]{2,})(?:\s (?P<ip_address>\d{1,3}(?:\.\d{1,3}){3}))?\s (?P<state>\S )

See the regex demo.

Now, the location group pattern is (?P<location>.*?) and it matches any char, 0 or more occurrences but as few times as possible, other than line break chars, and it is possible here since the next group pattern, country group, is now (?P<country>[A-Z]{2,}) and matches any substring of two or more uppercase ASCII letters.

Note I also "spelled out" the ip_address group pattern and made the whole part with initial whitespaces optional, (?:\s (?P<ip_address>\d{1,3}(?:\.\d{1,3}){3}))?.
