Different rules to read a Text File (Line by Line) in VB

Good afternoon,

I am working with Visual-Studio 2010 and I need to read one text file line by line and compare each line to some set of rules (some of these depend of others).

The idea is: I am taking the configuration from almost 500 Cisco equipments (Routers, Switches, IPS, Firewalls) and compare the configurations with a set of rules depending on the Hardware and the purpose for each command.

How can I create a set of rules with variables such as "If Begin with" or "If end with" or "If contains" and so on but that I can add new rules WITHOUT modifying the source code (I don't know if I am clear) but having like a ListBox where I can add/delete/modify the rules, and one big script that can understand these rules?

Any help will be appreciated!

------- Modify:

If you know of a script previously created that allows to "Create" a "Language" to compare text strings according a modifyble set of rules, it will be awesome!

I think the Regex class is your best friend: have a look at the "Remarks" section in its documentation page[^].

But, how do I create some sort of "Rule list" that I can Create/Delete/Modify/re-order?

I've been trying with ListView, but it doesn't seem to be the best way.

Oh, and Thanks!

Perhaps a quick example will help you to understand me:

I got this text:

Cisco Adaptive Security Appliance Software Version 8.0(5)
Device Manager Version 6.3(1)

Compiled on Mon 02-Nov-09 21:22 by builders
System image file is "disk0:/asa805-k8.bin"

And line by line I will need:

1st line: "If the first characters are "Cisco Adaptative Security Appl..." take the part after "Version" and print.
2nd line: The same with the 6.3(1)
Ignore 3rd and 4th
5th Line: take System Image Filename (between ") without the ".

And in some lines I will need to validate three or four things at the same time.
