title: Access Data Dumper nested Perl Hash
body: <p>I have a Perl hash reference <code>$artifact</code> that I am printing using Data::Dumper.</p>
  
  <p>The output of <code>print Dumper ($artifact);</code> returns the following.</p>
  
  <pre><code>$VAR1 = bless( {
               '_content' =&gt; '{
    "results" : [ {
  "uri" : "http://localhost:port/myfile.tar"
     } ]
  }',);
  </code></pre>
  
  <p>However, I am having trouble trying to specifically access the value of URI, i.e. I want to check if <code>uri</code> has a value or not.</p>
  
  <p>Thanks!</p>
  
  <p>Edit: Just some context. I am using the 'artifact_search' method from the Artifactory::Client perl module</p>
