well yes, I currently use JSON to do a similar recursive directory list output, where I don't need to retain the order of the pages:
use strict;
use warnings;
use JSON;
sub rec_tree {
my $n = $_[0] = {};
my @s;
find( sub {
$n = (pop @s)->[1] while @s and $File::Find::dir ne $s[-1][0];
return $n->{$_} = data_me($_) if -f;
/$bandir/ and $File::Find::prune = 1;
/$hidedir/ and $File::Find::prune = 1;
push @s,[ $File::Find::name,$n ];
$n = $n->{$_} = {};
}, $_[1]);
$_[0]{$_[1]} = delete $_[0]{'.'};
}
my $out;
rec_tree($out,shift);
my $jsout = JSON->new->allow_nonref->encode($out);
but as I mentioned, a similar recursive approach to parsing the @path data above defeats me, hence the hard coding, which at least retains the correct order in the output..

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
