If you change the game, you change the win. Tell us all of the contexts in which you hope to find your desired string.

JavaFan's regex worked for your first example because you showed a short, unambiguous introduction to your goal string. /\S/ matches on non-whitespace; there's no whitespace in your first example between /has address / and your goal string. Note that the single space following the last 's' is included in the regex.

Matching on /A/ doesn't work in your second example because the introduction to your goal string is not /A/; it's /A\s+/. This would not be real smart; it's not likely to be unique.

Formulate your problem clearly. Prepare a short list of all the various forms of input data you expect to see; and for each form, desired output. Then it is easy, even possible, to construct a solution.
