如何使用export-CliXml导出Invoke-RestRequest返回的原始XML

Question

如何使用PowerShell从eXist获得仅<notes/>的curl结果？

PS /home/nicholas> 
PS /home/nicholas> $url='http://localhost:8080/exist/rest/db/scripts/notes.xq'
PS /home/nicholas> 
PS /home/nicholas> $url                                                       
http://localhost:8080/exist/rest/db/scripts/notes.xq
PS /home/nicholas> 
PS /home/nicholas> $result=Invoke-RestMethod -Method Get -Uri $url -Headers @{"Content-Type" = "text/xml"}
PS /home/nicholas> 
PS /home/nicholas> $result
notes

PS /home/nicholas> 
PS /home/nicholas> $result | Export-Clixml ./result.xml
PS /home/nicholas> 
PS /home/nicholas> Get-Content ./result.xml                                                               
<Objs Version="1.1.0.1" xmlns="http://schemas.microsoft.com/powershell/2004/04">
<Obj RefId="0">
<XD>&lt;notes /&gt;</XD>
</Obj>
</Objs>
PS /home/nicholas> 
PS /home/nicholas> exit
nicholas@mordor:~$ 
nicholas@mordor:~$ curl http://localhost:8080/exist/rest/db/scripts/notes.xq
<notes/>nicholas@mordor:~$ 
nicholas@mordor:~$ 

为什么上面的XML有XD标签，目的是什么？

帮助文件说明：

描述

Export-Clixmlcmdlet创建公共语言基础结构(CLI(一个或多个对象的基于XML的表示形式并将其存储在文件中。然后可以使用Import-Clixmlcmdlet重新创建基于该文件的内容保存的对象。有关详细信息关于CLI，请参阅语言独立性(/dotnet/standard/语言独立性(。

This cmdlet is similar to `ConvertTo-Xml`, except that `Export-Clixml` stores the resulting XML in a file. `ConvertTo-XML` 
returns the XML, so you can continue to process it in PowerShell.
A valuable use of `Export-Clixml` on Windows computers is to export credentials and secure strings securely as XML. For an 
example, see Example 3.

调用OuterXml工作：

PS /home/nicholas> 
PS /home/nicholas> $url                                                                                   
http://localhost:8080/exist/rest/db/scripts/notes.xq
PS /home/nicholas> 
PS /home/nicholas> $result=Invoke-RestMethod -Method Get -Uri $url -Headers @{"Content-Type" = "text/xml"}
PS /home/nicholas> 
PS /home/nicholas> $result.OuterXml                                                                       
<notes />
PS /home/nicholas> 
PS /home/nicholas> ($result | ConvertTo-Xml).OuterXml                                                     
<?xml version="1.0" encoding="utf-8"?><Objects><Object Type="System.Xml.XmlDocument">System.Xml.XmlDocument</Object></Objects>
PS /home/nicholas> 

但是你怎么检查它是XML呢？或者，甚至成型良好？
