Question

我正在尝试从批处理文件的输出中创建PowerShell PSObject。

我正在调用这样的批处理文件，它给了我一个包含批处理文件输出的对象：

function browseGateway {
  & $migrationUtilityScript "browse" "-z" "$sourceGateway" "-showIds" "--hideProgress" |
    select -Skip 1 |
    Tee-Object -Variable gatewayItems |
    Out-Null |
    Sort-Object
  Clear-Host
  return $gatewayItems
}

输出如下：

folder          27fa3a0eb01caf5f1e31b6aeadd68d35    _Management and internal
folder          2ab9e48a1b83968c3844d93bc0919919    Mediclinic
folder          2c0a788b7f39a0415b423f14c0aa9e9c    OAuth
folder          a49ab6404138110fbd6c993cc9b87e46    customers
folder          b015056834707a42a07bcbfbbeb0a6dd    Users
folder          b015056834707a42a07bcbfbbeb2ca34    Product Offerings
folder          e001cfd0c1c1ffaa18e187b5e72fc718    OTK-3.2.00
policy          20a437bb3db29c1700a4f074773ffa41    DemoLogo
service         2ab9e48a1b83968c3844d93bc08ba780    kevinGMU

service         3afaef13bd772e8e25acfe85c4d101a7    Error
service         88f089fba30183fc4f18b7b7d05f5889    test

我想将它们放入PowerShell对象中进行进一步处理：

第1栏：类型
第2列：ID
第3栏：姓名

我很确定你需要使用New-Object，但我不完全确定如何对信息进行排序。我是否需要为每个单词使用正则表达式并将其进一步拆分？

Answer 1

由于您在制表符分隔文件中有效阅读，因此您无需使用RegEx，尽管您当然可以采用这种方式。在$items对象中输入原始输入后，可以使用以下语句将其转换为PSObject数组：

$items| ForEach-Object {
  $properties = $_ -Split "`t"
  New-Object PSObject -Property @{
    Type = $properties[0].Trim();
    ID = $properties[1].Trim();
    Name = $properties[2].Trim();
  }
}

结果：

Name                     ID                               Type
----                     --                               ----

如果您想使用RegEx，只需将$_.Split换成等效的$_ -Match <RegEx>，而不是引用$properties数组，而是引用$matches变量。在Jouni Heikniemi博客上有一个exceptionally good run down of RegEx in PowerShell。

你可以用一些-split s很容易地做到这一点 - 对于像这样简单的东西，正则表达式有点过分。

$Content = (Invoke-WebRequest "http://pastebin.com/raw/591dk6Gj").Content

$FinalObj = $Content -split "`r`n" | % {
    $Delimited = $_ -split "`t"

    [PSCustomObject]@{
        Col1 = $Delimited[0]
        Col2 = $Delimited[1]
        Col3 = $Delimited[2]
    }
}

return $FinalObj

你最终得到的$ FinalObj包含：

Col1            Col2                             Col3
