Many thanks to everyone who replied to my RE scoping problem. I have been able
to simplify my code considerably. Much appreciated.
I have a data structure like this (this is simplified - each image has many
fields):
$database = {
imagedata => {
'image1' => {
'filename' => [ 'foo.gif' ],
},
'image2' => {
'filename' => [ 'bar.gif' ],
},
'image3' => {
'filename' => [ 'foobar.jpg' ].
}
}
};
I am extracting the filename for each image using:
foreach $id ( keys %{ $database->{ 'image' } } ) {
push @filenames, $database->{ 'image'}->{ $id }->{ 'filename' }[ 0 ];
}
Is there any way I can generate a list of filenames without using a foreach
loop? I feel I should be able to access it by referring the the keys of the
imageX hash as a list, but I can't get my head around the syntax.
TIA,
Richard
