How to write a parser and a widget (in the form of buttons) that will expand like a tree when pressed?

Answer 1

1. Decompose
Write parser and widget = write parser + write widget
2. Understand
I need to write an xml parser, for that I'll google it . Perhaps it makes sense to google something more specific , for sure my problem has already been solved before me. For the widget, I need a graphical interface, I'll google about it too . I note that people most often advise tkinter, it is worth paying attention to .
3. Write
