PowerShell 根据字典循环替换指定目录下所有文件中的字符串

PS:

# 定义要搜索的目录和关键字-替换字符串对
$directory = "D:\xxx\xxx"
$replacements = @{
    "<variable_type>JVM</variable_type>" = "<variable_type>CURRENT_JOB</variable_type>"
    "<variable_type>PARENT_JOB</variable_type>" = "<variable_type>CURRENT_JOB</variable_type>"
    "<variable_type>ROOT_JOB</variable_type>" = "<variable_type>CURRENT_JOB</variable_type>"
}

# 获取所有 .kjb 和 .ktr 文件
Get-ChildItem -Path $directory -Recurse -Include *.kjb, *.ktr | ForEach-Object {
    $filePath = $_.FullName
    $content = Get-Content -Path $filePath

    # 遍历每个关键字-替换字符串对进行替换
    foreach ($key in $replacements.Keys) {
        $content = $content -replace [regex]::Escape($key), $replacements[$key]
        
        $matches = Select-String -Path $filePath -Pattern $key
        if ($matches) {
            $newContent = $content -replace [regex]::Escape($key), $replacements[$key]
            # 将修改后的内容写回文件
            $newContent | Set-Content -Path $filePath
            Write-Output "Replaced keyword in file: $filePath $key" 
        }
    }
}
