PowerShell uses the .Net framework XmlDocument so you could call the load method to load the xml into an XmlDocument object like this:
PowerShell 使用 .Net 框架 XmlDocument，因此您可以调用 load 方法将 xml 加载到 XmlDocument 对象中，如下所示：
#Option 1
$doc = New-Object System.Xml.XmlDocument
$doc.Load("http://ilo-ip/xmldata?item=All")
#Option 2
[xml]$doc = (New-Object System.Net.WebClient).DownloadString("http://ilo-ip/xmldata?item=All")
# Your XML will then be in the $doc and the names of the XML nodes can be used as
# properties to access the values they hold. This short example shows how you would
# access the value held in the SPN nodes from your sample XML
Write-Host $doc.RIMP.HSI.SPN
If your looking for more information on working with the XML once it has been loaded check out Dr. Tobias Weltner's eBookat PowerShell.com, chapter 14covers XML.
如果您在加载 XML 后寻找有关使用 XML 的更多信息，请查看PowerShell.com 上Tobias Weltner 博士的电子书，第 14 章介绍了 XML。

Sure. You can use the .NET WebClient object to download XML from the web and then use the [xml] type to interpret a string as XML like so:
当然。您可以使用 .NET WebClient 对象从 Web 下载 XML，然后使用 [xml] 类型将字符串解释为 XML，如下所示：
$url = "http://blogs.msdn.com/powershell/rss.xml"
[xml]$xml = (new-object System.Net.WebClient).DownloadString($url)
$xml.rss.channel | Foreach {$_.item} |
Where {[DateTime]$_.pubDate -gt (Get-Date).AddMonths(-1)} |
Format-Table Title
