in thread Why XML::Smart module can't work

Yes, after inserting print Dumper $XML_1, i got the ojbect, but why i can't print $ref?

My really intention is to parse the result of get request and print the result i wanted into a .csv file. 
#!/usr/bin/perl

use XML::Smart;
use Data::Dumper;
use warnings;
use strict;

my @array = ();
my %data = ();

open OUTFILE, '>result2.csv' or die $!;
open FILE, 'fund.txt' or die $!;

while (<FILE>)
{
      chomp;
      my $XML = XML::Smart->new("http://cmsbeta.morningstar.com/api/v2
+/2008428323/securities/$_"."/documents?colids=590&fields=*");
      print Dumper $XML;
  
      eval{
        %data = %{$XML->{Document}->{Content}->{People}};
         };
         
      for my $li (keys %data){
          print "$li:$data{$li}"."\n";
          push (@array,$data{$li});
          }

       print OUTFILE ("$_,","@array"."\n");
        @array = ();  
}     

close(OUTFILE);
close(FILE);
exit;

the result i got is

                          'g' => \*Object::MultiType::Saver::NULL,
                          'b' => \sub { "DUMMY" }

I still got nowhere.I can use XML::Simple to finish the similar task, but i think XML::Smart is more cool so i want to try it.

    That object you got back looks just like mine did when it failed to connect to the URL. Are you sure it is contacting the web server? Try printing "http://cmsbeta.morningstar.com/api/v2/2008428323/securities/$_"."/documents?colids=590&fields=*\n" and check you can connect to the resulting URL, with a browser, from the machine where your Perl is running

    Cheers,
    R.

      I use print Dumper object; and search the reason on line, finally it is resolved.

      Thanks!
