Attempt to bless into a reference while using XML::Twig

I am using the module XML::Twig for processing XML. While trying to run the nparse method with pretty_print option, I get an error. Following is the code:

use strict;
use XML::Twig;
use Data::Dumper;

my $xml_string = q{some xml string};
my $twig = XML::Twig->new();

$twig->nparse_pp( pretty_print => 'indented', $xml_string);

and the error message:

Attempt to bless into a reference at local/5.16/lib/perl5/XML/Twig.pm line 463.

Did I miss something?

Did I miss something

  • use strict; use warnings;
  • You never actually parse your $xml_string
  • you never declare or open $stdout. (Maybe you mean STDOUT)?
  • You use both XML::LibXML and XML::Twig.
  • nparse_pp implicitly sets pretty_print => 'indented' already.

Post some code that actually compiles and runs, and we might be able to help.

But perhaps you want something like;

my $twig = XML::Twig -> parse ( $xml_string );
$twig -> set_pretty_print ( 'indented' ); 
$twig -> print;
