Re^6: Regex to match a Cisco ACL by Anonymous Monk on May 22, 2011 at 17:14 UTC
Thanks a bunch! Your updated code is indeed amazing, for its level of detail and re-usable tokens. It just gives a greater level of control and granularity over matching schema without having to resort to a code that looks like hieroglyphics. In hindsight, it was silly of me to ask again without checking the grammar. The last 3 rules failing is no surprise since the grammar doesn't account for it yet. I should produce a complete code soon, for the sake of others looking for the same stuff. May I ask whether it is possible to code multi-line grammar also in to regex? For e.g the below section of config file `object-group network NOC-NC-NC1 network-object 192.162.137.0 255.255.255.0 network-object 192.162.146.0 255.255.255.0 object-group network NOC-NC-NC2 network-object 192.162.131.0 255.255.255.0 network-object 192.162.134.0 255.255.255.0` [download] Should be read into a hash of arrays as: `$object_hash{"NOC-NC-NC1"} => ["192.162.137.0 255.255.255.0","192.162. +146.0 255.255.255.0"] $object_hash{"NOC-NC-NC2"} => ["192.162.131.0 255.255.255.0","192.162. +134.0 255.255.255.0"]` [download]	[reply] [d/l] [select]

object-group network NOC-NC-NC1
 network-object 192.162.137.0 255.255.255.0

 network-object 192.162.134.0 255.255.255.0

Should be read into a hash of arrays as:

$object_hash{"NOC-NC-NC1"} => ["192.162.137.0 255.255.255.0","192.162.
+146.0 255.255.255.0"]
$object_hash{"NOC-NC-NC2"} => ["192.162.131.0 255.255.255.0","192.162.
+134.0 255.255.255.0"]
