Ok, that didn't really come across in your email.
http://augeas.net/
...does what you want. It has a lense (their term for a config file
description) for ISC dhcpd, which is a very similar syntax. It should be
relatively trivial to turn out a lense for ISC bind.
Or use Config::Parser, or adapt the script I sent round (which in fact
was the reason I wrote it); tokenisation of the bind config file is
easy, and the core grammar is straightforward because everything is
;-terminated, with the form:
item = thing+ block semicolon
thing = word | quoted-string
block = { item+ }

Not entirely. There is at least one construct that looks like this (using your
terms):
thing+ block thing block semicolon
For example, within the controls statement:
inet * allow { trusted; } keys { some.key; };

Named.conf logical blocks
Hi Guys, Does anyone have a sample grammar for pharsing named.conf into a data structure? Perl or PHP are preffered, but anything would be fine just to get a clear picture about grammar and logical blocks.

The only think I ever wrote was a quick python hack that used a big
regexp and an eat block function. Maybe it'll be of some interest, but
beware - regexp engines are not parsers, as jwz once famously pointed
out: You have a problem, and you decide to solve it with regexps. Now
you have two problems. ;o)
Anyway, break the regexp up and it's fairly obvious what it's doing. You
can get better results with a proper state-machine based parser.

def eat(toklist):
all = []
v = []
while toklist:
t = toklist.pop(0)
if t=='{':
inner = eat(toklist)
v.append(inner)
elif t=='}' and toklist and toklist[0]==';':
break

all.append(v)
v = []
else:
v.append(t)
return all
data = sys.stdin.read()
tokens = token_re.findall(data)

RE: Named.conf logical blocks
there is a perl module out there that may help:
http://cpan.uwinnipeg.ca/htdocs/BIND-Config-Parser/BIND/Config/Parser.html
I don't know - I'm not much of a perl monkey (or any of one, really), but I may
work for what you'd like.
