Depending on whether you're dealing with an actual array, or an associative array (a hash), the answer could be either of the following:

my $search = $data[2];
[download]

...or...

my $search = $data{content};
[download]

...assuming your array or hash are named @data or %data.

And this assumes also that I understood your ambiguously worded question. If I misunderstood it, please rephrase it in a followup so we can gain a better understanding of your need.
