in thread Bind zone file search

The m modifier will not help here. I (incorrectly) assumed that there was only one zone stanza per file. Processing multiple zone stanzas requires globally matching and preventing part of the regex from being 'greedy.' Try the following line:

$hash{$1} = $2
   while $data =~ /zone\s+"([^"]+)".+?masters\s+{[\s#\/]*([a-zA-Z0-9.-
+]+)[\s#\/;]*}/sg;

You'll note that: while has replaced if, there's a ? right after the + preceding masters, and the globally modifier is used.

while is used to process all matches; the ? prevents the regex from being 'greedy,' so it doesn't start the match at the beginning of a zone stanza and end the match with the last stanza.

This is really close, but not quite right. This regex is matching commented zone directives and if the comment is found after the real one is overwriting good answers for bad ones. I need to avoid commented stanzas. Since commented stanzas include comment characters prior to the match of zone, I think I need a way to ensure that matches on the word zone. Am I thinking correctly?	[reply]

By "commented," do you mean those containing either the "//" or "#" characters? Do you want to avoid all zone stanzas that contain those characters and use only those zone stanzas that don't contain those comment characters, i.e., "//" and "#"?	[reply]

right, I need to avoid stanzas that begin with the // or #	[reply]
