( [id://3333]=superdoc: print w/replies, xml ) Need Help??

DISREGARD BELOW!!! I figured it out... I forgot to use encode_json on $data{$key} to properly format the output. Thanks for the help and suggestions!

That works! Thank you for the reply. The only issue I am having now is with the output. I'm trying to get the output to be in the form:

$key . "\t"' . $data{$key} . "\n";

But when I iterate through the %data hash, the key and the tab come out as expected, but the value comes out as an array reference. I've tried to dereference it with no success. The dumper output for one key->value pair of the %data hash shows this:

'5557a6bed3793133754d288e2b58763a' => [ [ 2197, 840, 751, 6 ], { '16501' => 1 } ]

This looks as though the value contains both an array and a hash. Is there a way I can dereference those so that my output prints those values out as a string rather than the reference? For example, I currently get this:

5557a6bed3793133754d288e2b58763a ARRAY(0x441c780)

When what I'm after is this:

5557a6bed3793133754d288e2b58763a [[2197,840,751,6],{"16501":1}]

...and here's the code I'm using to output the pairs:

foreach $key (keys %data) { print $key . "\t" . "$data{$key}" . "\n"; }

Any ideas how to dereference that $data{key} to get the string instead of the array reference?

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
