    What do you think (?<=) and (?=) do? Why did you write them?

    The regex you wrote matches a string like 4444B within a longer substring, so maybe you're doing something else wrong.

    This might do what yo uwant:
    The \b restricts the matches to word boundaries, so it won't report matches in the middle of a longer "word" (which may include digits), like "123456789ABCD".
