Tools > Map Compare is your go-to tool for just about anything. Add filters for Cache Type and Disabled/Archived. Select the event types (if on a PC press ctrl to select multiple options), select Archived and show One Found. Select Location to reflect the area concerned (keep blank for whole world if needed).
This will produce a map showing all events you have attended, under which is a list (select your name under the map first). If you are a paid member of Project GC this can be added to a vGPS and then exported to a GPX, text file or spreadsheet.
