mr007619 has asked for the wisdom of the Perl Monks concerning the following question:
Hello Monks - I have read over perlreftut and perldsc enough times to get through most of my issues - but I'm now experiencing a problem I can't get past: Below is an example Data Dumper output.
$VAR1 = { 'somethingunknown' => [ { 'attachedto' => 'Server1 +', 'val2' => 'x.x.x.x', 'expires' => '7', }, { 'attachedto' => undef, 'val2' => 'x.x.x.x', 'expires' => '7', }, ] }; $VAR1 = { 'someothername' => [ { 'attachedto' => 'server4', 'val2', => 'xyz', 'expires' => '24' } ] };
My problem is, I would typically access data using something like
print $element->{'somethingunknown'}[0]{'val2'}";While I'm using a loop how do I know that what I'm looking for is $element->{'somethingunknown'} vs $element->{'someothername'}. Any help would be much appreciated. Everything I've tried to do to access the actual name of the value just gives me errors, either telling me it's a hash or I can't splice an array that way etc.
