将 pnputil 输出解析为特定类的已发布名称 [英] Parse pnputil output to published name for specific class

问题描述

在 PowerShell 中，在我输入pnputil.exe -e"后，我会得到一个驱动程序信息列表，如下所示.我需要从列表中获取班级监视器的发布名称并将oem8.inf"存储到 $monitor_name 中.我可以使用哪个命令来搜索 class = monitor 并将其发布的名称提取到变量中.因为属性发布名称"有空格，所以我不知道如何使这个工作.

In PowerShell, after I type "pnputil.exe -e", I get a list of driver info as below. I need to get class monitor's published name from the list and store "oem8.inf" into $monitor_name. Which command can I use to search for class = monitor and extract it's published name to a variable. Because the attribute "published name" has space, so I have no idea how to make this work.

Published name :            oem8.inf    
Driver package provider :   HP
Class :                     Monitors
Driver date and version :   07/25/2013 2.2.0.0    
Signer name :               Microsoft Windows Hardware Compatibility Publisher

Published name :            oem6.inf
Driver package provider :   Canon
Class :                     Printers
Driver date and version :   06/21/2006 6.1.7600.16385
Signer name :               Microsoft Windows

Published name :            oem1.inf
Driver package provider :   Microsoft
Class :                     Printers
Driver date and version :   06/21/2006 10.0.14393.0
Signer name :               Microsoft Windows

推荐答案

ConnorLSW 的有用回答就是方法去，他的方法说明了一个重要的观点:

ConnorLSW's helpful answer is the way to go and his approach illustrates an important point:

如果您使用 PowerShell cmdlet，则不需要字符串操作来提取信息 - PowerShell 的面向对象特性允许与传统的输出文本解析技术相比，这些解决方案更强大、更方便.

If you use PowerShell cmdlets, there is no need for string manipulation in order to extract information - PowerShell's object-oriented nature allows for solutions that are both more robust and more convenient compared to traditional output-text-parsing techniques.

也就是说，如果需要，PowerShell 也具有强大的字符串解析功能:

That said, if needed, PowerShell has powerful string parsing features too:

$monitor_name = pnputil.exe -e | Select-String -Context 2 'Class :\s+ Monitors' | 
  ForEach-Object { ($_.Context.PreContext[0] -split ' : +')[1] }

使用您的样本输入，这会产生:

With your sample input, this yields:

oem8.inf
