XML路径包含引号，使用PowerShell脚本更改值并保存到原始文件[重复]

Question

我想用PowerShell脚本修改以下两个路径中的值，

使用以下代码获取值。如何修改它们并保存到原始文件中？

例如： 1.将以下路径的值改为5.0

([xml] (Get-Content -Raw file.xml)).Map.StyleGroup.RootTopicDefaultsGroup.DefaultSubTopicShape.RightMargin

2.将以下路径的值改为false

([xml] (Get-Content -Raw file.xml)).Map.Custom.UpdatedNamedView

1. 保存到原始文件

注意： 使用替换方法不起作用，因为实际文档中有很多相同的字段

文件.xml：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ap:Map xmlns:ap="http://schemas.mindjet.com/MindManager/Application/2003" OId="pdhXhObhC0avKT9HfmeUMQ==" xmlns:pri="http://schemas.mindjet.com/MindManager/Primitive/2003" xmlns:cor="http://schemas.mindjet.com/MindManager/Core/2003" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.mindjet.com/MindManager/Application/2003 http://schemas.mindjet.com/MindManager/Application/2003 http://schemas.mindjet.com/MindManager/Core/2003 http://schemas.mindjet.com/MindManager/Core/2003 http://schemas.mindjet.com/MindManager/Delta/2003 http://schemas.mindjet.com/MindManager/Delta/2003 http://schemas.mindjet.com/MindManager/Primitive/2003 http://schemas.mindjet.com/MindManager/Primitive/2003">

PowerShell 为 Microsoft powershellgallery.com 中的 XML 和其他模块提供特定的 cmdlet。
