Hi,

There are more than one id tag and url in the example you gave.
Let's take the example you gave as one line as it arrives as given in the OP. Please note that how those line(s) are inputted (or arrives to use your words) into the perl script was not shown.
You can do like so:

use warnings;
use strict;

my $line =

If then you need put your data in an hash, you could simply just do

 my %hash_contain;
  
  if(...){
    ...
   %hash_contain = @arr;
  }
[download]

Since, you will always have itag ids and urls(except otherwise, which was not told us), then your hash look like so:


  35 => ...,
  44 => ...,

Hope this helps.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
