Powershell:查找和替换由换行符分割的单词 [英] Powershell: Find and replace words split by newline

问题描述

所以我有一个看起来像这样的文本文件:

So I have a text file that looks something like this:

Members : {USER\member1, USER\member2, US
           ER\member3, USER\member4, USER
           \member5, USER\member6}

我想删除USER\.下面的代码会删除它，但当它被换行符分割时不会删除它，例如当 US 在一行而 ER\ 在另一行时.

and I would like to remove USER\. The following code removes it but not when it's split by a newline, for example when US on one line and ER\ on another line.

Foreach-Object { %{$_.Replace('USER\', '') }

把 `n 或 `r 放在里面是行不通的.任何帮助表示赞赏.

Putting `n or `r in there doesn't work. Any help is appreciated.

推荐答案

试试这个:

PS > ((Get-Content .\t.txt) | % { $_.Trim() }) -join "" -replace "USER\\"
Members : {member1, member2, member3, member4, member5, member6}

如果文本在字符串数组中，请使用您的变量切换 (Get-Content .\t.txt).如果您在字符串(不是数组)变量中有文本，请使用:

If the text is in a string-array, switch out (Get-Content .\t.txt) with your variable. If you have the text in a string(not array) variable, use:

($MYSTRINGVAR.Split("`r`n") | % { $_.Trim() }) -join "" -replace "USER\\"

EDIT 只需修改成员"部分:

EDIT Just modify the "Members" part:

$text = (Get-Content .\input.txt) -join "`r`n"
($text | Select-String '(?s)(?<=Members : \{)(.+?)(?=\})' -AllMatches).Matches | % {
        $text = $text.Replace($_.Value, ($_.Value -split "`r`n" | % { $_.Trim() }) -join "" -replace "USER\\")
}
$text | Set-Content output.txt
