Parse perl array

Question

I\'m not familiar with perl and am trying to edit an irssi translation script. The result from a web request returns as:

$result = {
 \"data\" => {
  \"transl         


        

Answer 1

That would be

$result->{data}->{translations}->[0]->{translatedText};

$result is a hash ref. The key 'data' points at yet another hash ref, which has a key 'translations' pointing at an array ref. The first and only element in that array ref has a key 'translatedText' which points at the data of interest: 'Halloween'.

Answer 2

"Halloween" could be obtained as:

$result->{"data"}->{"translations"}->[0]->{"translatedText"}

The arrows after the first one can be omitted, so an even shorter variant would be:

$result->{"data"}{"translations"}[0]{"translatedText"}

Basically you have multiple indirections at different levels:

• reference to a hash
• its "data" key being a reference to another hash
• the "translations" key of the last hash being a reference to an array
• the first element of that array is a reference to a hash
• the "translatedText" key of that hash is a string
