Reading web page information

Hello everybody,
I would like to know if there is a way, using for example a Wifi or Ethernet shield to make Arduino read information from a web page. Simple text data in a known format.

Best,
Diego

With an ethernet shield and the client sample sketch loaded, you should be able to make it fetch any web page. Mapping the web server name to an IP address is not trivial. Handling the returned data is not trivial, but it isn't terribly hard, either. The issues are likely to center around the minimal memory of the Arduino and how much of that is used by the ethernet code.

Thanks a lot for your answer! It seems it is easiear to handle the info by a computer and the serial comunicate with arduino, isn't it?

Cheaper, too.
