No, not at all.
The trick is finding the precise dividing line, the code complexity/data

RegEx solutions are conveniently compact to write, but given the
complexity of the RegEx subsystem they tend to be slower than more
brute-force solutions.
Being a benchmarking fan I couldn't resist testing this latest case,
extracting numerals from an alphanumeric string.
Below is a test
That is interesting and nice.
I have only run one test but it was mixed pretty good
my result was 94 67 with the repeat for each being the
fastest method.
Thanks to both Mark Richard for the valuable help.
