perlquestion roidlagratte Hi everybody ! I used Webservices::GData::YouTube to retrieve some informations on the web site Youtube. I can retrieve some data from the hash return by query and search_video (for exemple i can retrieve with ${hash}{'_entity'}{'children'}[4]{'array'}[0]['scheme'} who return http://schemas.google.com/g/2005#kind ) but i can retrieve the url thumbnail in 480 or other pixels size. I suspect the usage of Webservices::GData::Node::Atom::Id necessary and i thing it's only a problem to explore the hash. but i can find some help on the man page of this module If someone could help me i would be very graceful. Below a Dump of the hash generate by Data::Dumper. Thanks very much and sorry for my bad english.
