XML Reading from outside the .unity3d

Is it possible to read an xml file from outside the .unity3d file?

I understand that Resource.Load can be used to load a content from within the Resources folder. But I believe this file again resides inside the .unity3d file. I want to read an xml file outside the .unity3d file (or any other path) so that I dont have the necessity to re-build my project again.

Any idea?

You need to use the .NET class with C#.
There is the System.Xml package that can be used for any purpose: load, save, append… etc.

Take a look at the MSDN page System.Xml Spazio dei nomi | Microsoft Learn
