And what does, "does not work" mean this time?

I got a pretty clear error message when running your script:

Global symbol "$data" requires explicit package name ...

Which led me to this line:

push @data, $data->[0]{'xml_api_reply'}{'weather'}{'report_date'} = {' +-data' => $today };

Which I changed to this:

push @data, $weather_data->[0]{'xml_api_reply'}{'weather'}{'report_dat +e'} = {'-data' => $today };

Now it runs without errors.

    It runs, but look at the extra line added to end end of the file:
    ... $VAR1->[1] = $VAR1->[0]{'xml_api_reply'}{'weather'}{'report_date'};

      Ah, ok. Try these changes:

      # no need for this loop: # for my $w_data (@$weather_data) { # push @data, $w_data; # } # Now add 'report_date' key and its value at the appropriate level. #push @data, $weather_data->[0]{'xml_api_reply'}{'weather'}{'report_da +te'} = { '-data' => $today #}; push @{$weather_data->[0]{'xml_api_reply'}{'weather'}{'report_date'}}, + { '-data' => $today }; # print Dumper(\@data); print Dumper(\$weather_data);

    Here is the answer:
    $data[0]{'xml_api_reply'}{'weather'}{'report_date'} = {'-data' => $tod +ay };

    No need to use push!

marto wonders what fresh hell the firefox update has brought, apart from maxing out CPUs
1nickt was looking into Firefox Extended Support releases yesterday. You don't have to go with the updates!
[erix]: wonderfully red sun here
[LanX]: FF has become a source of instability :(
[1nickt]: erix not so wonderful for the lungs :-(
[erix]: the stuff is pretty high up as I understand it; I have not felt any effect on lungs/breathing
