it want extract bold ones. 5 digit number(german). should not match telephone numbers 43564 366334 or 45433 / 45663,etc in example above.

i tried ^\b\d{5} thats not beginning.

some hints me working?

thanks hints

you add negative look-ahead assertion avoid matches phone numbers.

\b[0124678][0-9]{4}\b(?!\s?[ \/-]\s?[0-9]+)

if you're using ruby 1.9, can add negative look-behind assertion well.
