捕获多行，多组到Powershell变量 [英] Capture multiline, multi-group to Powershell variables

问题描述

理想情况下，我想从ipconfig创建一个对象，该对象允许我们向下钻取每个适配器的属性，如下所示:$ ip.$ lan.$ mac作为lan适配器的mac地址.

Ideally, I would like to create an object from ipconfig that allows us to drilldown to each adapter's attributes like this: $ip.$lan.$mac for the lan adapter's mac address.

首先，我想开发一种方法来将每个适配器匹配将这3组(适配器类型，适配器名称，适配器属性)捕获到Powershell变量中(首选对象):

To start, I would like to develop a way to capture these 3 groups (adapter type, adapter name, adapter attributes) per adapter match into Powershell variables (objects are preferred): https://regex101.com/r/wZ3sV1/1

这里有一些想法可以捕获以太网适配器"部分的三个部分，但是它们仅捕获以太网适配器本地连接:":

Here are some ideas to capture three parts of the Ethernet adapter section, but they are only capturing "Ethernet adapter Local Area Connection:":

$ip = ipconfig /all

$ip_lan = $ip | Select-String -pattern "(Ethernet [^a]*adapter) (Local[^:]+):\s*(([^\n]+\n)*)" -AllMatches | Foreach {$_.Matches} | ForEach-Object {$_.Value}

$regex_lan = [regex]"(Ethernet [^a]*adapter) (Local[^:]+):\n*(( +[^\n]+\n)*)"
$regex_lan.Matches($ip)
$regex_lan.Matches($ip).value

还有，有没有办法像这样捕获组提取的名称?:

Also, is there a way to capture the name of the group extraction like this?:

   Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller

成为描述= Realtek PCIe GBE系列控制器

becomes Description = Realtek PCIe GBE Family Controller

推荐答案

我知道这并不能直接回答您的问题.而不是使用Regex解析ipconfig的输出.相反，您可以使用Get-NetIPConfiguration来获取更易于处理的powershell对象.

I know this doesn't directly answer your question. But rather than parsing the output of ipconfig with Regex. You could instead use Get-NetIPConfiguration to get a powershell object that is easier to deal with.

PS> $ip = Get-NetIPConfiguration
PS> $ip

InterfaceAlias       : Ethernet
InterfaceIndex       : 12
InterfaceDescription : Intel(R) Ethernet Connection I217-LM
NetProfile.Name      : xyz.com
IPv4Address          : 10.20.102.162
IPv6DefaultGateway   :
IPv4DefaultGateway   : 10.20.102.1
DNSServer            : 10.20.100.9
                       10.20.100.11
                       10.20.100.13

PS> $ip.IPv4Address

IPAddress         : 10.20.102.162
InterfaceIndex    : 12
InterfaceAlias    : Ethernet
AddressFamily     : IPv4
Type              : Unicast
PrefixLength      : 23
PrefixOrigin      : Dhcp
SuffixOrigin      : Dhcp
AddressState      : Preferred
ValidLifetime     : 05:16:53
PreferredLifetime : 05:16:53
SkipAsSource      : False
PolicyStore       : ActiveStore
PSComputerName    :

因此，您可以执行以下操作以获取要获取的值.

Thus you can do the following to get the values you are looking to acquire.

$ip.InterfaceAlias
$ip.InterfaceDescription
$ip.IPv4Address.IPAddress

要获取MAC地址，可以使用Get-NetAdapter cmdlet.

To get the MAC the address you can use the Get-NetAdapter cmdlet.

$adapter = Get-NetAdapter
$adapter.MacAddress

您可以使用InterfaceIndex将这两个信息关联起来.然后返回一个哈希表，使每个哈希表都可访问.下面创建了这些组合对象的数组.

You can correlate the two pieces of information using the InterfaceIndex. Then return a hashtable that makes each accessible. The following creates an array of these combined objects.

$combined = Get-NetIPConfiguration | ForEach-Object {
    $adapter = Get-NetAdapter -InterfaceIndex $_.InterfaceIndex
    @{ IP = $_; Adapter = $adapter }
}
