在VB中读取文本文件(逐行)的不同规则 [英] Different rules to read a Text File (Line by Line) in VB

问题描述

下午好，

我正在使用Visual Studio 2010，需要逐行读取一个文本文件，并将每一行与一组规则进行比较(其中一些规则取决于其他规则).

我的想法是:我从将近500台Cisco设备(路由器，交换机，IPS，防火墙)中获取配置，并将配置与一组规则进行比较，具体取决于硬件和每个命令的用途.

如何创建带有变量的规则集，例如如果以...开头"，如果以...结尾"或如果包含"等等，但是我可以在不修改源代码的情况下添加新规则(我不知道(如果我很清楚)，但是就像一个ListBox，可以在其中添加/删除/修改规则，还有一个可以理解这些规则的大脚本?

任何帮助将不胜感激！


-------修改:

如果您知道先前创建的脚本，该脚本允许创建"语言"以根据可修改的规则集比较文本字符串，那就太棒了！

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!

推荐答案

我认为Regex类是您最好的朋友:在其

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

也许一个简单的例子可以帮助您理解我:

我收到了这段文字:

Cisco自适应安全设备软件版本8.0(5)
设备管理器版本6.3(1)

由builders于2009年11月2日星期一21:22编译
系统映像文件为"disk0:/asa805-k8.bin"

而我需要逐行:

第一行:如果第一个字符是"Cisco Adaptative Security Appl ..."，则在版本"之后打印并打印.
第二行:与6.3(1)相同
忽略第三和第四
第五行:取系统映像文件名(在之间")，不带.

在某些情况下，我需要同时验证三到四件事.

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.
