Maybe you can use this example as a base: 
#!/usr/bin/perl
use warnings;
use strict;
# by jdporter of perlmonks, converts a dir tree to xml
use File::Find;
use XML::Simple;
#my $root = shift or die "Usage: $0 rootdir\n";
my $root = shift || '.';

my %tree;

find(
   sub
   { #print "$File::Find::name\n"; 
     my @path = split m,/,, $File::Find::name; 
     my $tree = \%tree; 
     $tree = (($tree->{'dir'} ||= {})->{shift @path} ||= {}) 
        while @path > ( -d _ ? 0 : 1 ); @path and # it's a file 
           push @{ $tree->{'file'} ||= [] }, shift @path; }, 
           $root ); 
           
print XMLout( \%tree );
