String PowerShell将两个字符串之间的文本替换为日期和时间

我一直在尝试如何在PowerShell中执行以下操作，但运气不佳

---

我想替换messageid>和之间的所有内容。这个示例应该可以帮助您实现所需的结果

$text = @'
Some line of text
random text <messageid> who knows </messageid> some other text
another line
'@

$text -replace '(?s)(?<=messageid>).+?(?=</messageid)',(Get-Date).ToString('dddd dd-MM-yyyy HH:mm:ss')

Some line of text
random text <messageid>Monday 12-10-2020 21:54:04</messageid> some other text
another line

$text=@'
一行文字
随机文本谁知道其他文本
另一行
'@
$text-替换“（？s）（？）。+？（？）=实际的原始文本是什么？嘿，道格，大意是：9348399343-38493-Det-100
$text = @'
Some line of text
random text <messageid> who knows </messageid> some other text
another line
'@

$text -replace '(?s)(?<=messageid>).+?(?=</messageid)',(Get-Date).ToString('dddd dd-MM-yyyy HH:mm:ss')

Some line of text
random text <messageid>Monday 12-10-2020 21:54:04</messageid> some other text
another line

'<MessageID>9348399343-38493-Det-100</MessageID>' -replace '(?s)(?<=messageid>).+?(?=</messageid)',(Get-Date).ToString('dddd dd-MM-yyyy HH:mm:ss')

<MessageID>Monday 12-10-2020 21:58:56</MessageID>
