将Powershell变量传递到XML

我首先要说的是，我确信这是一场骗局

问题是我很难弄清楚如何修改它以供我使用

我的XML是

<?xml version="1.0"?>
<ImageSHDriveConfig>
  <PartitionsFile>partitions.txt</PartitionsFile>
  <SSDSettings>
    <!-- <DriveManufacturer>ASMT</DriveManufacturer> -->
    <DriveManufacturer>ASMT</DriveManufacturer>
    <DriveMinSize>127000000000</DriveMinSize>
    <DriveMaxSize>129000000000</DriveMaxSize>
  </SSDSettings>
  <ImageSettings ImageType="WIM">
     <ImagePath>Z:\Public\Users\test\OnwardImages\V1WIM\RS_CLIENT_TEAM\19508.1000.191030-1730\</ImagePath>
    <!-- <ImagePath>BionicKnee-TH2_RELEASE</ImagePath> -->
    <WIMFileName>install.wim</WIMFileName>
    <SWMFileName>install.swm</SWMFileName>
    <SWMPattern>install*.swm</SWMPattern>
  </ImageSettings>
</ImageSHDriveConfig>

由此产生的错误是：

The property 'ImagePath' cannot be found on this object. Verify that the property exists and can be set.
At C:\OnwardInjecting\tests\xmltest.ps1:7 char:1
+ $XML.ImageSettings.ImagePath="$ImagePath"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : PropertyNotFound

如何将Powershell$ImagePath传递到XML中

从我试图遵循的示例来看，这个解决方案可能适合：

谢谢你的帮助

您的简单测试代码有什么问题？发生了什么？很好的问题！我补充了之前的遗漏。感谢您指出这一点。因此，

config.xml

是在外部创建的，根据提供的代码，您的脚本将只设置

元素的值？是否保证该元素始终存在，或者有时您的脚本可能正在创建它？如果在使用

[xml]$xml=（Get Content$XMLname）

读取该元素时，该元素在文件中不存在，则相应的属性也将不存在。@BACON脚本仅提供该元素的值。XML中已经存在字段，因此每次读取文件时都保证存在该字段。再加上下次读取该文件时，该元素仍将在上次运行脚本时存在。您的简单测试代码有什么问题？发生了什么？很好的问题！我补充了之前的遗漏。感谢您指出这一点。因此，
