在保留空格的同时修改 xml [英] Modify xml while preserving whitespace

问题描述

我在尝试在保留空格的同时替换 XML 文件中的属性时遇到了几个问题.

I'm running into several problems trying to replace an attribute in an XML file while preserving whitespace.

$xml = [xml](get-content data.xml)
$xml.Path.To.Attribute = $value
set-content data.xml [String]$value

结果:删除了微不足道的空格(即换行符)

Result: Insigificant whitespace (namely newlines) are removed

$xml = new-object xml
$xml.PreserveWhitespace = true
$xml.PreserveWhitespace

结果:PreserveWhitespace 仍然是 false

$xml = get-content data.xml
$xml = [regex]::replace($xml, "pattern", "replacement")
set-content data.xml $xml

结果:[regex]::replace 弄乱了行尾

我在这里吃疯狂的药丸吗?

Am I taking crazy pills here?

推荐答案

问题都是相关的:Get-Content 返回文本文件的行，而不是文本本身.当转换回字符串时，这些行会完全合并.

The problems were all related: Get-Content returns lines of the text file, not the text itself. When cast back to a string, the lines are combined outright.

最好的解决方案是使用:

The best solution was to use:

$xml = [xml]([System.IO.File]::ReadAllText("data.xml"))
