Detailed Description

Filters a string according to a given regex.

Regex behavior:

A regex containing a capture group will produce only the matched content of that capture group, otherwise the whole regex match is returned. All capture groups after the first one will be ignored.

Example regex:

Input	Regex	Result
Highway 61 revisited	\d+	61
Highway 61 revisited	Highway \d+	Highway 61
Highway 61 revisited	Highway (\d+)	61
Highway 61 revisited	\w+	Highway
Highway 61 revisited	(\w+) (\d+)	Highway (not an error)
