Hi folks,

Greetings!

I looked into the XML reference code coming together with the installer package. It seems there is a relationship between struct members and XML elements. But I didn't find example to construct a struct to match with my XML contents. Please advise.
It seems it is a nested structure with customized value. How do I handle this into a C++ struct?

Many thanks!
