The instance is empty. That's because you read all of it and passed it to the first regex. Change to: side = urlopen(http://www.website.no;).read() then: liste = compile_obj.findall(side) liste = compile_obj2.findall(side) That reads the site's contents once, then you can do whatever you want with it in your program. I'm not sure why you had the self. reference to compile_obj, so mix to fit your circumstances :) Brian - -- - ---[Office 68.6F]--[Outside 54.2F]--[Server 100.6F]--[Coaster 69.6F]--- - ---[ LADY MARY (367013060) @ 47 36.3071 -122 23.1817]--- Software, Linux, Microcontrollers http://www.brianlane.com AIS Parser SDKhttp://www.aisparser.com -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.8 (Darwin) Comment: Remember Lexington Green! iD8DBQFJBi/UIftj/pcSws0RAjtiAJ45Sp++yj8jUhir6lwehLqRzBJswwCfREh7 J83jy1sN1xf8Gi+dWZs9GNM= =8YQT -END PGP SIGNATURE- ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

The instance is empty. How can I easiest pick up more information from the site without opening it more than once? Just remember the data. It's like reading a file, you can't read the same file twice without re-opening, but you can remember the (string) data from the file and use it however you want to: data = side.read() liste = self.compile_obj.findall(data) liste2 = self.compile_obj2.findall(data) Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
