Question

我正在尝试查找超出我的阈值限制的所有Azure实例。我的系统检测到实例，现在我想从文本中提取所有机器并采取措施。在下面的文本中，我只有PowerShell作为一个选项来标识所有以RD *开头的实例。

似乎您正在显示某种HTML报告，并希望使用Powershell对其进行分析。对于此解决方案，您需要将报告保存为.html文件。

让我们假设您已这样做，并将报告保存到D:\Report.html的磁盘上然后您可以这样做：

# 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()
}

使用您提供的报告，这将会产生

Name           Issue                                                                                                                       
----           -----
