Mark please that was only a part of the message. Thank you for the explanation, but can you explain me XML Pull Parser, the line I asked for, and maybe a link or two where to find simple examples on how to start using it, or to start parsing XML? I wouldn't ask in this group if I only wanted to cry on my own shoulders because of the java system.
