Given a string like:

Recipient: [email protected]

Action: failed

Status: 5.0.0 (permanent failure)

Diagnostic: No

How do I get the 5.0.0 and permanent failure only if it's always after Status: ? ?

Thanks

var regex = /Status: ([0-9.]+) (([a-zA-Z ]+))/

var result = string.match(regex);

var statusNumber = result[1];

var statusString = result[2];

You should extend these: [0-9.], [a-zA-Z ] selectors if you expect other characters in these values. For now the first one expects numbers and dots, the second characters and spaces
