Your original expression looked right to me, please post some sample code
so we can see what you are doing, and remember that:

Escape characters need to be doubly escaped if the regex is embedded in a
C-string (the first escape gets gobbled up by the compiler).

That the regex_match algorithm *does not* search through the string, it
only matches the whole of the input or not at all (use regex_search to
search the input for a match.
