scaler to array

[jamsman]

i have a string that contains the following:

{
'Attachment03' => {
'Filesize' => '3321',
'Filename' => 'res.xml',
'Description' => 'Miricals can come true'
},
'Attachment01' => {
'Filesize' => '3321',
'Filename' => 'res.xml',
'Description' => 'Does it work'
},
'Attachment02' => {
'Filesize' => '3321',
'Filename' => 'res.xml',
'Description' => 'Miricals can come true'
}
}


now the number of 'Attachments' can be any number i need to get this information in to some kind of array that also contains the other informtion in a field


any ideas

how would you want to store, all the values you have now, in your new "array"??

Why would you want an array?? when you have everything in a hash of hashes, which is more editable and a lot faster...

Are you sure it's a string? It looks like a data structure. If it really is a string (from a config file?) then you could autovivify it as a data structure like this

my $data;
eval "\$data = $string";
die $@ if $@; # syntax error in string

# now use your data like this
foreach my $att ( sort keys %$data ) {
  # att is Attachment01, Attachment02, Attachment03 in turn
  print "Filesize is $data->{$att}{Filesize}\n";
  print "Filename is $data->{$att}{Filename}\n";
  print "Description is $data->{$att}{Description}\n";
}

Is this what you are after?
