Re: XML::Simple "transforming data"

[Thelonious]

XML::Simple's interface is pretty odd in that it outputs something different than it takes in by default. (Maybe it could be even a little more simple - and more Perlish...?) But there's an option:

ForceArray => 1 *# in - important*
    This option should be set to '1' to force nested elements to be
    represented as arrays even when there is only one.

...that you can use like so:

use XML::Simple;

my $xml = XMLin(join('',<DATA>),ForceArray => 1);

print XMLout($xml);

...I think that it outputs something very similar to what you're looking for...

I think it'll do exactly what he wants if you add "RootName=>'meta'" to the call to XMLOut()
