Hi,
I have a form with fields such as City, State and Zip.
I need to make a call like "http://cep.republicavirtual.com.br/web_cep.php?cep=91010000&formato=xml."
When the ZipCode field is full or as a button "Search" is clicked, the application will be done and the City and State fields will filled.
How can I do this?
