XML::Simple in Perl - Values

Let's consider this XML.

<acme>
  <name role="main">Bugs Bunny</character>
</acme>

 

 

Data::Dumper can be used to understand how XML::Simple is interpreting the XML. Here is an example of how to use Data::Dumper.

#!/usr/bin/perl
use strict;
use warnings;
use XML::Simple;
use Data::Dumper;

my $xml= XMLin("example.xml");
print Dumper $xml;

 

Which will produce the following.

  • "name" is the root key
  • "content" and "id" are child keys below the root key
  • "Bugs Bunny" is a value of the "content" key
  • "1" is a value of the "id" key 
  • Data inside of { } is interepreted as a hash
$VAR1 = {
          'name' => {
                     'content' => 'Bugs Bunny',
                     'role' => 'main'
               }
        };

 

In this example, "Bugs Bunny" will be printed.

print $xml->{'name'}->{'content'};

 

In this example, "main" will be printed.

print $xml->{'name'}->{'role'};
