在PowerShell中带有嵌入式双引号的正则表达式模式 [英] Regex pattern with embedded double quotes in PowerShell

问题描述

需要使用PowerShell在文档上搜索以下关键字:

Following keyword need to be searched on document using PowerShell:

["Allowed Acquisition Clean-Up Period" 

$keyword = ""
Get-Content $SourceFileName | Select-String -Pattern $keyword

我要搜索的字符串中有双引号，所以我在如何在此 $ keyword 中提及.

String which I'm searching for has double quotes in it, so I'm struggling how to mention in this $keyword.

推荐答案

显然，您不仅有双引号，而且还有一个方括号.方括号是正则表达式中的元字符(用于定义字符类)，因此您也需要转义这些字符.

Apparently you not only have double quotes, but also an opening square bracket. Square brackets are meta-characters in regular expressions (for defining character classes), so you need to escape those too.

用单引号定义表达式:

$keyword = '\["Allowed Acquisition Clean-Up Period"'

或使用反引号对嵌套的双引号进行转义:

or escape nested double quotes with backticks:

$keyword = "\[`"Allowed Acquisition Clean-Up Period`""
