我正在尝试查找超出阈值限制的所有Azure实例。我的系统检测到了这些实例，现在我想从文本中提取所有机器并采取行动。我只有PowerShell作为一个选项来识别以下文本中以RD*开头的所有实例。

您似乎正在显示某种HTML报告，并希望使用Powershell进行解析。对于此解决方案，您需要将报告保存在.html文件中。
假设您已执行了此操作，并将报告保存到D:Report.html的磁盘上然后你可以做：
# read the report file as string
$htmlReport = Get-Content -Path 'D:Report.html' -Raw
# create a Regular Expression object to capture the RD machines and their issues
$regex = [regex] '<dt>(?<Name>RD[^<]*)</dt><dd>(?<Issue>[^<]+)</dd>'
$matches = $regex.Match($htmlReport)
while ($matches.Success) {
New-Object -TypeName PSObject -Property ([ordered]@{ Name = $matches.Groups['Name'].Value; Issue = $matches.Groups['Issue'].Value })
$matches = $matches.NextMatch()
}
使用你给出的报告，这将产生
Name Issue
