in reply to regular expression

The initial deathstar ( .* ) is greedy, qv.

IOW, there's nothing left for your capture after leading .* matched everything in your string.

Read, instead, about look-aheads or try capturing the first Sanity_001_ and the balance of the string (to a second capture clause), and printing/saving only $2 -- either can help you, but learning about look-aheads (and the general category, of which it's a part, "look arounds") will help you greatly, even in the short term.
