JavaFX: How to save application data in a xml file and restore back?

I've several check boxes, text fields and two buttons (Save & Open) like this:

Let say after checking the check boxes some or all and filling the text fields some or all when user will click on the save button, it will open a file chooser and save the selected and filled information into a xml file.

And when user click on the open button he can choose the previously saved xml file using the file chooser.

So what I want is when user choose the previously saved xml file I want to parse the stored data and according to that data I want to check only those check boxes and fill only those text fields which user checked and filled at the time of saving please help me how can I achieve this.
