Question

I want a regex that can match either one group, or two groups. Here is an example of how it looks. Either like this:

(key)

Or like this:

(key “value”)

So far I’ve come up with an expression which matches the latter example. But I have no idea how to modify it so it matches either the first one, or the latter one. Here it is:

\((?P<property_key>[^() ]+) "(?P<property_value>[^"]*)"\)

Answer 1

I believe you are looking for regex pattern

\((?P<property_key>\w+)(?:\s+"(?P<property_value>\w+)")?\)
