修改xml节点使用powershell的值

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？

eg: 1.将下面路径的值改为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

3.保存到原文件

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">

Answer 1

• 将您的输入文件解析为[xml] (System.Xml.XmlDocument) 实例并保存该实例。

• 通过PowerShell's adaptation of the XML DOM，使用点符号修改该实例的元素。

• 使用[xml] 实例的System.Xml.XmlDocument.Save 方法将修改后的DOM 保存到（原始）文件中。

# Get the full path of the input file.
$filePath = Convert-Path file.xml

# Parse the file into an XML DOM.
[xml] $xml = Get-Content -Raw $filePath

# Modify the attributes of interest.

$xml.Map.StyleGroup.RootTopicDefaultsGroup.DefaultSubTopicShape.RightMargin = '5.0'

$xml.Map.Custom.UpdatedNamedView = 'false'

# Save the modified DOM back to the input file.
# Note: Be sure to use a *full* path, because .NET's working dir
#       usually differs from PowerShell's.
$xml.Save($filePath)
