上面是存储在文本文件中的数据集，要求是分析数据并选择servername，date，patch并将该数据放入具有服务器名称，日期和补丁详细信息的自定义Power Shell对象中。请帮我做到这一点
解决方法
使用switch -Regex -File遍历文本文件中的每一行都可以解决问题。
下面的代码解析了所有污秽，但是您可以注释掉结果中不希望出现的任何属性
$result = switch -Regex -File 'D:\Test\patches.txt' {
'^[-\w]+$' { $server = $_ }
'[AP]M$' { $date = [datetime]::ParseExact($_,'F',[cultureinfo]'en-US') }
'^(\d+)\s+(\w+)\s+(KB\d+)\s+(\d+\s[KM]B)\s+(.+)' {
# create and output an object
[PsCustomObject]@{
Server = $server
Date = $date
X = $matches[1]
Status = $matches[2]
KB = $matches[3]
Size = $matches[4]
Title = $matches[5]
}
}
}
# output on screen
$result | Format-Table -AutoSize
# output to CSV file
$result | Export-Csv -Path 'D:\Test\patchresults.csv' -NoTypeInformation
使用示例文件输出
