使用PowerShell标识以RD*开头的实例名称

我正在尝试查找所有超出阈值限制的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作为一个选项来标识以下文本中以RD*开头的所有实例

{DescriptionEntryId=343578460；
问题:
已为此xxxxxx的59个不同实例触发xxxxxx
描述：设置此项以识别问题验证：警告RDXXXXXXXX在15分钟内达到阈值（2）。评估窗口期间的数据点范围在2.393和6.054之间。RDXXXXXXXX达到阈值（2）满足时间为15分钟中的15分钟。评估窗口期间的数据点范围在2.722和6.813之间。RDXXXXXXXXXXXX阈值（2）满足时间为15分钟中的15分钟。评估窗口期间的数据点范围在2.481和5.909之间。RDXXXXXXXXXXXXXXXX阈值（2）在15分钟中的14分钟内达到。评估窗口期间的数据点范围在1.412和6.588之间。RDXXXXXXXXXXXX在15分钟中的15分钟内达到阈值（2）。评估窗口期间的数据点范围在3.375和6.24之间。RDXXXXXXXXXXXXXXXX达到阈值（2）在15分钟中的15分钟内满足。评估窗口期间的数据点范围在2.382和6.863之间。RDXXXXXXXXXXXX在15分钟中的14分钟内满足阈值（2）。评估窗口期间的数据点范围在0.418和11之间。RDXXXXXXXXXXXXXXXX在阈值（2）之间满足时间为15分钟中的15分钟。评估窗口期间的数据点范围在3.059和6.667之间。RDXXXXXXXXXXXX阈值（2）满足时间为15分钟中的15分钟。评估窗口期间的数据点范围在2.255和7.5之间。RDXXXXXXXXXXXXXXXX阈值（2）在15分钟中的15分钟内满足。评估窗口期间的数据点范围在2.545和5.291之间。RDXXXXXXXXXX阈值（2）在15分钟中的14分钟内满足。评估窗口期间的数据点范围在1.691和5.6之间。RDXXXXXXXXXXXXXX阈值（2）在15分钟中的14分钟内满足。评估窗口期间的数据点范围在2到6.755之间。RDXXXXXXXXXX在15分钟中的15分钟内满足阈值（2）

您似乎正在显示某种HTML报告，并希望使用Powershell解析该报告。对于此解决方案，您需要将报告保存在.HTML文件中

假设您这样做了，并将报告保存到磁盘
D:\report.html
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()
} 

非常感谢，我会在我的脚本中加入这一点，你推荐任何正则表达式工具来让像我这样的新蜜蜂使用regex变得容易吗？我个人喜欢RegexBuddy，但它不是免费的。网上有很多regex测试人员，比如google for it，你会找到一个你喜欢的。
