Stop regex capturing after double spaces

Question

I'm trying to match the content of a string up to the occurrence of a double space (ignoring the case when the double space is after the autor/name identifier) or any other character different than A-Z or a single blank space, until the moment I came up with the following regular expression, although the \S does match anything except a blank space.

(AUTOR|NAME):?([A-Z ]\S)+


AUTOR:  LEANDRO LUCIANI  TAVARES -- This should match up to 'AUTOR:  LEANDRO LUCIANI'

AUTOR LEANDRO LUCIANI \TAVARES -- This should match up to 'AUTOR LEANDRO LUCIANI' discarding anything after the backslash

AUTOR       LEANDRO TAVARES -- This should match up to 'AUTOR       LEANDRO TAVARES'

Edit:

I am trying to run it on C# so it must be compatible with the .NET implementation of regular expressions.

Thanks in advance, Leandro Tavares

Answer 1

What you are looking for is probably something like that:

(AUTOR|NAME)[\s:]\s*([A-Z]+( [A-Z]+)*)

Answer 2

This PCRE works for me:

/(AUTOR|NAME):?\s*([A-Z ]+?)(?:  | \\|\\|$)/
