PowerShell - 从文本文件中查找并复制 URL，然后复制到由管道分隔的另一个文本文件

Question

我需要一个Powershell脚本，该脚本读取给定文件中出现的关键字"Match："和"Replace："，并将其前面的行复制到另一个文本文件中的新行，以管道分隔和结束。下面是示例。

输入

20/01/2016 00:00:18 Some Lines of Text here
20/01/2016 00:00:18 Some Lines of Text here
20/01/2016 00:00:18 Match: /test/OLD/Myfolders/Folders/Folder1/         
20/01/2016 00:00:19 Replace: /test2/NEW/currentfiles/  
20/01/2016 00:00:19 Some Lines of Text here
20/01/2016 00:00:20 Some Lines of Text here
20/01/2016 00:00:20 Some Lines of Text here
20/01/2016 00:00:20 Match: /match/2015/pages/
20/01/2016 00:00:20 Replace: /replace/2016/pages/
20/01/2016 00:00:21 Some Lines of Text here

输出

/test/OLD/Myfolders/Folders/Folder1/|/test2/NEW/currentfiles/|
/match/2015/pages/|/replace/2016/pages/|

所以每次找到关键字"Match："时，它前面的 URL 都会复制到新文本文件中的新行，后跟管道和"替换："前面的 URL

/Matching URL/|/Replacing URL/|
/Matching URL/|/Replacing URL/|

你可以试试这个：

Get-Content input.txt | ForEach-Object {
    if ($_.tostring().Contains("Match")) {
        $i = $_.tostring().IndexOf("Match")
        $url = $_.ToString().Substring($i+7).Trim() + "|"
    } elseif ($_.tostring().Contains("Replace")) {
        $i = $_.ToString().IndexOf("Replace")
        $url = $url + $_.ToString().Substring($i+9).Trim() + "|"| Out-File ouput.txt -Append
        $url = $null
    }
}
