in reply to Re^14: Bind zone file search
in thread Bind zone file search

Try the following modified regex in the subroutine:

/(?<!#|\/)\s*zone\s+"([^"]+)".+?masters\s+{[\s#\/]*([a-zA-Z0-9.-]+)[\s +#\/;]*}/sg

Added:

(?<!#|\/)\s*zone ^ ^ ^ | | | | | + - 0+ whitespaces | + - Match "zone" and 0+ whitespaces that are not preceded by an " +#" or "/" + - Negative lookbehind
