<?xml version="1.0" encoding="utf-8"?>
<appPool name="MyAppPool">
  <enable32BitAppOnWin64>true</enable32BitAppOnWin64>
  <managedPipelineMode>Integrated</managedPipelineMode>
  <managedRuntimeVersion>v4.0</managedRuntimeVersion>
  <autoStart>true</autoStart>
</appPool>

这是我正在尝试的：

#read in the xml
$appPoolXml = [xml](Get-Content $file)
 
#get the name of the app pool
$name = $appPoolXml.appPool.name
 
#iterate over the nodes and update the app pool
$appPoolXml.appPool.ChildNodes | % {
     #this is where the problem exists
     set-itemproperty IIS:\AppPools\$name -name $_.Name -value $_.Value
}

$_.Name返回节点的名称(即enable32BitAppOnWin64),这是正确的,但是.Value属性不返回任何东西.如何提取我想要的数据？
