xml - 使用 powershell 将具有多个值的元素添加到现有的 xml 文件

问题描述

我正在自动化 SQL 报告服务，我需要将代理设置添加到 web.config 文件。我尝试在 powershell 中执行此操作，但我无法弄清楚如何通过 powershell 执行此操作。

我需要将以下 xml 代码添加到现有 web.config XML 文件的末尾

  <system.net>
    <defaultProxy enabled="true" useDefaultCredentials="true">
      <proxy bypassonlocal="True" proxyaddress="http://ocs.kennisnet.nl:3128" />
    </defaultProxy>
  </system.net>

完整的 xml 文件需要是：

<configuration>
  <system.web>
    <pages validateRequest="false">
      <controls>
        <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

我发现了很多代码示例，但似乎都没有工作，我设法创建了下面的代码，但它没有保存文件，而且我不知道如何添加第二个键值。希望你们中的一个人在这方面比我更熟练..

$file="web.config"
[xml]$xmlDoc = [System.Xml.XmlDocument](Get-Content $file)

$newEl=$xmlDoc.CreateElement("system.net")
$xmlDoc.configuration.AppendChild($newEl)  
$xmlDoc.Save($file)

$newEl=$xmlDoc.CreateElement("defaultProxy")   
$nameAtt1=$xmlDoc.CreateAttribute("enabled")
$nameAtt1.psbase.value="true"  
$newEl.SetAttributeNode($nameAtt1)  

$nameAtt2=$xmlDoc.CreateAttribute("useDefaultCredentials")  
$nameAtt2.psbase.value="true"    
$newEl.SetAttributeNode($nameAtt2) 
$xmlDoc.configuration["system.net"].AppendChild($newEl)  

$xmlDoc.Save($file)

最终结果需要创建完整的 XML 文件，如上图所示。

请帮忙...

解决方案

以下将在运行时元素之后插入新的 XML 数据：

$webconfig = [xml](Get-Content C:\temp\web.config)
$newxml = [xml](Get-Content c:\temp\new.xml)

$newNode = $webconfig.ImportNode($newxml.'system.net',$true)
$InsertAfterNode = $webconfig.configuration.runtime
$null = $webconfig.configuration.insertAfter($newNode,$InsertAfterNode)
$webconfig.Save("c:\temp\web.config")

$newNode存在，以便我们拥有该InsertAfter()方法的正确对象类型。对应的ImportNode()方法输出我们想要的对象类型。$true被传递，以便我们导入 的所有后代元素system.net。

我在处理文件时使用了完整路径。我相信该.Save()方法通常需要完整路径，因为它默认为特定目录。请注意，这不是通用代码，它依赖于您专门提供要插入新数据的元素。
