我尝试使用正则表达式，但只能更新1个值：

<valuesToReplace>
  <valueToReplace>
    <regExSearch>(\/PIP_Log[\w\W]*?[pP]roperties[\w\W]*?[lL]ibraries[\w\W]*?[pP]ypi[\w\W]*?"repo":\s)"(.*?[^\\])"</regExSearch>
    <replaceWith>__PATValue__</replaceWith>
  </valueToReplace>

  <valueToReplace>
    <regExSearch>('\/LS_New[\w\W]*?[pP]roperties[\w\W]*?[tT]ypeProperties[\w\W]*?"domain":\s"(.*?[^\\])")</regExSearch>
    <replaceWith>__LSDomainName__</replaceWith>
  </valueToReplace>
</valuesToReplace>

我在哪里丢失了？？？

你不应该直接偷看和戳入序列化文件（例如Json文件）。改为使用cmdlet反序列化文件，对对象进行更改并使用cmdlet再次序列化：

JSON是一种数据结构。您不使用正则表达式，因为

convertfromjson

创建了一个漂亮的PS对象。

foreach($valueToReplace in $configFile.valuesToReplace.valueToReplace)
        {
          
            $regEx = $valueToReplace.regExSearch
            $replaceValue = '"' + $valueToReplace.replaceWith + '"'
          
            $matches = [regex]::Matches($json, $regEx)
            
            $matchExactValueRegex = $matches.Value | Select-String -Pattern """repo\D:\s*(.*)" | % {$_.Matches.Groups[1].Value}
            $updateReplaceValue = $matches.Value | Select-String -Pattern "repo\D:\s\D__(.*)__""" | % {$_.Matches.Groups[1].Value}
            $updateReplaceValue = """$patValue"""
    
    $json1 = [regex]::Replace($json, $matchExactValueRegex , $updateReplaceValue)
    
    $matchExactValueRegex1 = $matches.Value | Select-String -Pattern """domain\D:\s*(.*)" | % {$_.Matches.Groups[1].Value}
            $updateReplaceValue1 = $matches.Value | Select-String -Pattern "domain\D:\s\D__(.*)__""" | % {$_.Matches.Groups[1].Value}
            $updateReplaceValue1 = """$domainURL"""
     
          
            $json = [regex]::Replace($json1, $matchExactValueRegex1 , $updateReplaceValue1)
          }
          else
          {
            Write-Warning "Inactive config value"
          }
        
        
        $json | Out-File $armFileWithReplacedValues

$Data = ConvertFrom-Json $Json
$Data[0].properties.typeproperties.domain = '_LSDomainName__'
$Data[1].properties.activities.typeproperties.libraries[1].pypi.repo = '__PATValue__'
