Re^2: Accessing an AoHoAoH

CountZero, not sure I understand. Ran Data::Dumper and got:

$VAR1 = {
          'chapter' => 'Basic',
          'page' => [
                      {
                        'paragraph' => 'lesson1'
                      },
                      {
                        'paragraph' => 'lesson2'
                      }
                    ]
        };
$VAR2 = {
          'chapter' => 'Advanced',
          'page' => [
                      {
                        'paragraph' => 'lesson3'
                      },
                      {
                        'paragraph' => 'lesson4'
                      }
                    ]
        };

What am I missing? Thanks

That's what you should get if you write something like `dump @AoH;` because `@AoH` "flattens" to a one-element list in the list context of the function call. (This was just a guess, but I'm sure in what I'll write below.) This way, however, you can not easily access the contents of the deep datastructure, as you can't index the array in such a way that it flattens automatically, so you have to use a 0 as a first array index, just as CountZero said. To change, either use a scalar variable, or (perhaps better) use an array variable, just assign it like `@AoH= ({...}, {...}, ...);`, not `@AoH= [{...}, {...}, ...];`.	[reply] [d/l] [select]

Try `print Dump(\@AoH);` Then you see the extra level of the `@AoH` array CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply] [d/l] [select]
