Hi, thanks. When you press Extract the extracted data shows in the Extracts tab in menu. It doesn't do anything immediatelly. That's not good UX and i'm gonna adress it somehow as someone else already suggested.

Or there were no data in Extracts after you tried to extract something? If you don't mind please open up an issue with sample data and xpath in https://github.com/Masa331/xml_fiddler/issues and i will look into it
