OCaml - Accessing absolute paths

I'm developing an application where I implement the GUI in QtQuick and the logic in OCaml, using lablqt. In QtQuick I use a FileDialog to select a file. I need to use the path that the FileDialog returns in my OCaml program but I get an error every time I do this.

The path returned by FileDialog is file:///home/thomas/Desktop/Sudoku/example.txt This is the correct path, but when I try to acces this file in OCaml I get the following error:

Fatal error: exception Sys_error("file:///home/thomas/Desktop/Sudoku/example.txt: No such file or directory")

How can I convert this path gotten from the FileDialog to a path I can use in OCaml?

You need to remove the protocol part from the returned url, i.e., this file://. You can do this either manually, or use uri library, that will handle it for you.
