在 PowerShell 中将 SOAP XML 行转置为列

Question

我一直在编写一个脚本，我想将以下 SOAP xml 响应元素从行转置到列，但我没有成功找到正确的解决方案。我正在使用 PowerShell 5.1.1.

以下是支持问题证据的 XML 要素：

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
 <soap:Body>
  <deviceListResponse xmlns="http://SERVERURL.domain/">
   <return>
    <items>
     <first>device.deviceid</first>
     <second>123456789</second>
     <key>device.deviceid</key>
     <value>123456789</value>
    </items>
    <items>
     <first>device.uri</first>
     <second>127.0.0.1</second>
     <key>device.uri</key>
     <value>127.0.0.1</value>
    </items>
    <items>
     <first>device.longname</first>
     <second>DESKTOP-123ABC456</second>
     <key>device.longname</key>
     <value>DESKTOP-123ABC456</value>
    </items>
    ...
   </return>
  </deviceListResponse>
 </soap:Body>
</soap:Envelope>

我使用 Invoke-WebRequest to HTTP POST 通过 -Body 参数获取设备信息。正文被认为是以下内容：

$body = @"
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ei2="http://SERVERURL.domain/">
   <soap:Header/>
   <soap:Body>
      <ei2:deviceList>
         <ei2:username>example@domain.com</ei2:username>
         <ei2:password>$($env:password)</ei2:password>
         <ei2:settings>
            <ei2:key>customerID</ei2:key>
            <ei2:value>123456</ei2:value>
         </ei2:settings>
      </ei2:deviceList>
   </soap:Body>
</soap:Envelope>
"@

我怎样才能制作出像样的东西，以便我可以在 PSCustomObject 方法中使用它？

编辑 1：我确实在使用 Invoke-WebRequest 方法时声明了 XML 变量。

以下将网络服务响应中的 <items> 元素转换为单个 [pscustomobject] 实例的属性，使用：

Select-Xml提取感兴趣的元素
结合一个ForEach-Object call that builds up a(n ordered) hash table来自感兴趣的子元素
之后转换为 [pscustomobject] 实例：

# Simplified sample response from the web service.
$xmlText = @'
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
 <soap:Body>
  <deviceListResponse xmlns="http://SERVERURL.domain/">
   <return>
    <items>
     <first>device.deviceid</first>
     <second>123456789</second>
     <key>device.deviceid</key>
     <value>123456789</value>
    </items>
    <items>
     <first>device.uri</first>
     <second>127.0.0.1</second>
     <key>device.uri</key>
     <value>127.0.0.1</value>
    </items>
    <items>
     <first>device.longname</first>
     <second>DESKTOP-123ABC456</second>
     <key>device.longname</key>
     <value>DESKTOP-123ABC456</value>
    </items>
   </return>
  </deviceListResponse>
 </soap:Body>
</soap:Envelope>
'@

# Initialize the ordered hashtable that will collect the key-value pairs
# from the XML
$oht = [ordered] @{}

# Loop over all <items> elements and add their <key> and <value>
# child elements as key-value pairs to the output hashtable.
Select-Xml -Content $xmlText //ns:items -Namespace @{ ns = 'http://SERVERURL.domain/'} |
  ForEach-Object {
    $oht[$_.Node.key] = $_.Node.value
  }

# If necessary, convert the ordered hashtable to a customobject.
$customObj = [pscustomobject] $oht

以上在 $customObj 中产生以下 [pscustomobject] 实例：

device.deviceid device.uri device.longname
--------------- ---------- ---------------
123456789       127.0.0.1  DESKTOP-123ABC456
