in thread explore a complexe hash structure return by Webservices::GData::YouTube

Thanks for reply, i will try to be more specific in my request.

I want to retrieve a particular data in structure type hash

To print all the hash, i use the code :

use strict; use warnings; use Data::Dumper; my $myquery="Robert Palmer"; use WebService::GData::YouTube; use WebService::GData::Error; my $yt = new WebService::GData::YouTube(); $yt->query()->q("$myquery")->limit(10,2); $yt->query($myquery)->maxresults(20); my $videos = $yt->search_video(); print Dumper($videos);

This will return:

$VAR1 = [ bless( { '_recorded' => bless( { '_children' => [], 'namespaces' => {} }, 'WebService::GData::YouTub +e::YT::Recorded' ), '_updated' => bless( { 'text' => '2012-12-10T13:35: +15.000Z', '_children' => [], 'namespaces' => {} }, 'WebService::GData::Node::A +tom::Updated' ), '_title' => bless( { 'text' => 'Robert Palmer - Add +icted To Love', '_children' => [], 'namespaces' => {} }, 'WebService::GData::Node::Ato +m::Title' ), '_id' => bless( { 'text' => 'tag:youtube.com,2008:v +ideo:XcATvu5f9vE', '_children' => [], 'namespaces' => {} }, 'WebService::GData::Node::Atom:: +Id' ), '_entity' => bless( { 'gd:etag' => 'W/"DEIFRH47eCp7 +I2A9WhNWEUk."', '_children' => [ bless( { 'te +xt' => '2009-12-25T07:54:08.000Z', '_c +hildren' => [], 'na +mespaces' => {} }, 'W +ebService::GData::Node::Atom::Published' ), bless( { '_c +hildren' => [], 'na +mespaces' => {} }, 'W +ebService::GData::Node::Atom::Summary' ), bless( { 'sr +c' => 'http://www.youtube.com/v/XcATvu5f9vE?version=3&f=videos&app=yo +utube_gdata', '_c +hildren' => [], 'ty +pe' => 'application/x-shockwave-flash', 'na +mespaces' => {} }, 'W +ebService::GData::Node::Atom::Content' ), bless( { 'ar +ray' => [ + bless( { + '_name' => bless( { + 'text' => 'RobertPalmerVEVO', + '_children' => [], + 'namespaces' => {} + }, 'WebService::GData::Node::Ato +m::Name' ), + '_uri' => bless( { + 'text' => 'http://gdata.youtube +.com/feeds/api/users/RobertPalmerVEVO', + '_children' => [], + 'namespaces' => {} + }, 'WebService::GData::Node::Atom +::Uri' ), + '_entity' => bless( { + '_children' => [ + $VAR1->[0]{ +'_entity'}{'_children'}[3]{'array'}[0]{'_name'}, + $VAR1->[0]{ +'_entity'}{'_children'}[3]{'array'}[0]{'_uri'} + ], + 'namespaces' => {} + }, 'WebService::GData::Node::A +tom::Author' ) + }, 'WebService::GData::Node::Atom::AuthorEntity' ) + ], 'ca +che' => {} }, 'W +ebService::GData::Collection' ), bless( { 'ar +ray' => [ + bless( { + '_children' => [], + 'scheme' => 'http://schemas.google.com/g/2005#kind +', + 'term' => 'http://gdata.youtube.com/schemas/2007#v +ideo', + 'namespaces' => {} + }, 'WebService::GData::Node::Atom::Category' ), + bless( { + '_children' => [], + 'label' => 'Music', + 'scheme' => 'http://gdata.youtube.com/schemas/2007 +/categories.cat', + 'term' => 'Music', + 'namespaces' => {} + }, 'WebService::GData::Node::Atom::Category' ) + ], 'ca +che' => {} }, 'W +ebService::GData::Collection' ), $VAR1->[0]{' +_id'}, bless( { 'ar +ray' => [ + bless( { + 'rel' => 'alternate', + 'href' => 'http://www.youtube.com/watch?v=XcATvu5f +9vE&feature=youtube_gdata', + '_children' => [], + 'type' => 'text/html', + 'namespaces' => {} + }, 'WebService::GData::Node::Atom::Link' ), + bless( { + 'rel' => 'http://gdata.youtube.com/schemas/2007#vi +deo.responses', + 'href' => 'http://gdata.youtube.com/feeds/api/vide +os/XcATvu5f9vE/responses', + '_children' => [], + 'type' => 'application/atom+xml', + 'namespaces' => {} + }, 'WebService::GData::Node::Atom::Link' ), + bless( { + 'rel' => 'http://gdata.youtube.com/schemas/2007#vi +deo.related', + 'href' => 'http://gdata.youtube.com/feeds/api/vide +os/XcATvu5f9vE/related', + '_children' => [], + 'type' => 'application/atom+xml', + 'namespaces' => {} + }, 'WebService::GData::Node::Atom::Link' ), + bless( { + 'rel' => 'http://gdata.youtube.com/schemas/2007#up +loader', + 'href' => 'http://gdata.youtube.com/feeds/api/user +s/2cgN9BQEA14z3ryXNmJjkA', + '_children' => [], + 'type' => 'application/atom+xml', + 'namespaces' => {} + }, 'WebService::GData::Node::Atom::Link' ), + bless( { + 'rel' => 'self', + 'href' => 'http://gdata.youtube.com/feeds/api/vide +os/XcATvu5f9vE', + '_children' => [], + 'type' => 'application/atom+xml', + 'namespaces' => {} + }, 'WebService::GData::Node::Atom::Link' ) + ], 'ca +che' => {} }, 'W +ebService::GData::Collection' ), $VAR1->[0]{' +_title'}, $VAR1->[0]{' +_updated'}, bless( { '_d +uration' => bless( { + 'seconds' => '236', + '_children' => [], + 'namespaces' => {} + }, 'WebService::GData::YouTube::YT::Duration' ), '_d +escription' => bless( { + 'text' => 'Music video by Robert Palmer perfo +rming Addicted To Love.
