Convert Arduino fs:File* into c++ std::File*

Question

it seemed too easy. I stored an xml file on a sdcard connected to my esp32. I use the SD.open() function to access the files stored on the sdcard. For parsing the xml file I downloaded the tinyxml2 library and tried to use the xmlDocument.LoadFile() function.

The problem is that the xmlDocument.LoadFile function is using a std::File pointer. The SD.open() function return an fs::File pointer.

The resulting error message in my ArduinoIDE is:

No matching function for call to tinyxml2::XMLDocument::LoadFile(fs::File*).

Does anybody has an idea how to convert the fs::File* into std::File*?

Thank you very much!

Thank you so much.

as @Galik mentioned, his hint was the key for me. But in the long run @Juraj suggestion to use json the better way.
