If you require each array to have the following format you can complete eliminate the array around the child tags. The position alone is enough to determine whether or not an array element is a nested tag. Eliminating the extra square brackets around each tag set would help keep the indentation from going halfway across the page or more.

  [0] tag name
  [1] attribute hash reference
  [2] data
  [3] ...: one array ref for each nested tag

Your sample data would then look like this:

[ family => { name => 'Kawasaki' } => undef,
  [father => {} => 'Yasushisa' ],
  [mother => {} => 'Chizuko' ],
  [children => {} => undef,
    [girl => {} => 'Shiori'],
    [boy  => {} => 'Yasuke'],
    [boy  => {} => 'Kairi']
  ]
]
