sanguine_perl has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am stuck by the problem of using XML::Smart module, it can't work. Recently, I want to use XML::Smart to parse the XML response, but i can't get any results,so i test the return as follows: 
#!/usr/bin/perl

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

#open FILE1, 'run.xml' or die $!;

my $XML_1 = XML::Smart->new('run.xml');
my $ref = $XML_1->{product};
print $ref;

I expect to see the reference of response, but after running it 
C:\Users\rchen4\Desktop\Perl_XML>perl script2.pl

C:\Users\rchen4\Desktop\Perl_XML>

[download]
no result. XML::Smart and Object::MultiType are all installed. Could someone be helpful?

    can you insert print Dumper $XML_1; after my $XML_1 = XML::Smart->new('run.xml'); to check you really got an XML::Smart object.

    Cheers,

      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

      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,
