从.config文件中删除特定元素

Question

我正在尝试从软件的配置文件中删除特定元素。它的格式类似于我以前可以解析的XML，但这一次似乎有所不同。由于它并没有真正包含任何敏感信息，因此我将在此处将配置文件放在我需要删除的元素中。对不起，很长的帖子。

<configuration>

我需要在最后删除“受信任的”值，但似乎无法找到一种找到它的方法。我仍然是所有这些。谢谢！

如果该值始终存在于其自己的线上，那么您不妨将其剪切而不是解析XML：

# element to remove
$string = '<value>trusted</value>'

# get all lines except the trusted element
$edited = Get-Content 'C:\path\to\file.config' | Where {$_ -NE $string}

# write back to file
$edited | Out-File 'C:\path\to\file.config'
