将迭代 SOAP XML 行转置为 PowerShell 中的列

Question

在的后续 post 中，我希望能够从 result 项目集中迭代键值对，如下所示：

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
 <soap:Body>
  <deviceListResponse xmlns="http://SERVERURL.domain/">
  <!-- Item 1 -->
   <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>
 <!-- Item 2 --> 
  <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-Bus</second>
  <key>device.longname</key>
  <value>DESKTOP-Bus</value>
  </items>
 </return>
 </deviceListResponse>
</soap:Body>
</soap:Envelope>

如何在 PowerShell 脚本中实现此目的？提前致谢。

Answer 1

只需要对 :

进行相对较小的调整

# Assume that $xmlText contains the XML text to parse.

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

Select-Xml -Content $xmlText //ns:items -Namespace @{ ns = 'http://SERVERURL.domain/'} |
  ForEach-Object {
    # See if an entry already exists for the key at hand.
    if ($oht.Contains($_.Node.key)) {
      # Convert the entry value into an array on demand and 
      # append the value at hand.
      [array] $oht[$_.Node.key] += $_.Node.value
    }
    else {
      # Create the entry, using the value as-is.
      $oht[$_.Node.key] = $_.Node.value
    }
  }

$customObj = [pscustomobject] $oht

$customObj # output

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

device.deviceid        device.uri             device.longname
---------------        ----------             ---------------
{123456789, 123456789} {127.0.0.1, 127.0.0.1} {DESKTOP-123ABC456, DESKTOP-Bus}

请注意，{ ... } 附件只是 PowerShell 输出格式化系统（可能令人困惑）表示值是集合（数组）的方式。
