Yup, they're HTML, all right. Now I'm thinking of moving this code to a separate command line app that I can call from the main application. It should work, but I'm not sure if I'd need to provide a runloop for the HTML importing to work. Well, easy enough to try. If not, I'll have to find some other method for importing the HTML._______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
