Regex into an Array

NathanE has asked for the wisdom of the Perl Monks concerning the following question:

Hello all; I'm currently working on a project which implements some XML based vulnerability tests into a remote forensics environment which allows the use of Perl to automate functions. Now, my problem is that I can't do a regex match to registry keys (the software doesn't allow it for some reason), but I need to do some simple pattern matching against keys as the XML tests call for it. I've been succesful in doing it in some cases, but without brute forcing through every key in a stupid mannor, I would like to split some of the simpler regex searches into an array to be acted and searched upon. Here's an example of what I'm looking at here;

^SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\Zone
+s\\[0-4]$

^SOFTWARE\\Microsoft\\Fpc\\Arrays\\\{[^\\]+\}\\Extensions\\Proxy-Plugi
+ns\\\{FE440D49-AB26-11D2-A101-00C04FB6CFB6\}$

So, basically - I'm just looking to extract an array of all possible combinations given a regex. Any help on this would be greatly appreciated. Thanks agian and take care.

I think that Regexp::Genex might be of interest ... but note that what you're asking is an impossible task, as there are an infinite number of patterns that match `/[^\\]+/` since it's a one-or-more match and is unbounded ... (i'm assuming Regexp::Genex has some protection against that)	[reply] [d/l]

I'm not completely sure to have understood what your actual problem could really be. But you can cerainly put regexen into an array. The `qr//` operator is your friend; it returns a blessed reference into a `Regex` object.	[reply] [d/l] [select]

Please see Reverse engineering regular expressions for more on the complexities of such a task and some ideas on how to proceed. Two modules that might help are YAPE::Regex::Explain and grinder's Regexp::Assemble. HTH, planetscape	[reply]
