更新配置 xml 文件并使用 powershell 保存它

Question

我需要更新此配置文件，使 'newVersion' 的所有值都需要更新为单个值。

<configuration>
<runtime>
<assemblyBinding>
  <dependentAssembly>
        <assemblyIdentity name="A" 
publicKeyToken="5d861ad8ad8cd06f" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-65534.65534.65534.65534" newVersion="4.0.0.103" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="B" publicKeyToken="ae714df8cd90bc8f" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-65534.65534.65534.65534" newVersion="4.0.0.103" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="C" publicKeyToken="22955931b98512b6" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-65534.65534.65534.65534" newVersion="4.0.0.103" />
      </dependentAssembly>
      <dependentAssembly>
                <assemblyIdentity name="D"
                                  publicKeyToken="585a888b4a9ba2e3"
                                  culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-65534.65534.65534.65534"
                                 newVersion="2.5.0.1286"/>

              </dependentAssembly>
    </assemblyBinding>
  </runtime>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
  </startup>
</configuration>

我已经在下面试过了

$appconfig='file location'
$doc = (Get-Content $appconfig) -as [Xml]
$obj = $doc.configuration.runtime.assemblyBinding.dependentAssembly
$obj2 = $obj.assemblyIdentity | where {$_.name -eq 'D'}
$obj.bindingRedirect.newVersion="1.1.1.1"
echo $obj.bindingRedirect.newVersion
$doc.Save($appconfig)

我知道这只会改变"D"部分，如何改变上面的A，B和C。感谢您的帮助！

(gc C:\temp\config.xml) -replace '(newversion=)".*?"' ,'"1.1.1.1"' # if you want to save the file add |sc c:\temp\config.xml
