in reply to A data structure for XML generation

If you've defined two explicit cases for $inner (scalar or array ref), you can always differentiate it from a hash ref, so why not just make the \%attr optional and just omit the empty hashes {}?

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

I also think your example had a couple minor errors (extra array ref and no punctuation between 'children' and its children.)

    Yes, I certainly thought of that. And you will often simply provide content without attributes, so I think that is a nice shorthand.
      You may use something like the lol structure of the method new_from_lol in HTML::Element, I think it is very compact and easy to handle.
