I'm trying to **get this given node value from the Sitecore configuration** (Sitecore 9 instance).

My first approach was to **read the configuration file** on which this value is defined. Pretty standard...

The issue is that I just realized that a customer can **add another configuration file to patch this value**, what would make my first approach return a wrong value.

What is the best way of reading the final computed Sitecore configuration (what we see in the `/showconfig.aspx`)?
