Question

看下面的xml示例，当您将其加载到powershell中时，不允许您在$ myXML.configuration.system.web之外的源进行点缀，因此不允许访问该元素的内部。这是因为元素名称中的句点吗？如果是这样，我无法更改，那么解决方法是什么？

我可以键入（例如）类型$ myXML.configuration.'system.web'，但是除非有意料之外，否则我将无法继续深入标签/元素，除非我做错了事（因此，）。我无法获取编译内部的程序集，甚至无法获取system.web内部的编译

我的最终目标是能够检查是否存在任何元素/值，如果不存在则将其添加，或者如果设置不正确则对其进行更改。

$path = "c:\temp\web2.config";
[xml]$myXML = Get-Content $path;

下面是xml内容

<?xml version="1.0" encoding="UTF-8"?>
