title: Puppet - How to get all values in the same level of the hierarchy?
body: <p>Let's say that I have the following data in the heira:</p>
  
  <pre><code># web01.example.com.yaml
  mykey: one
  </code></pre>
  
  <p>and</p>
  
  <pre><code># web02.example.com.yaml
  mykey: two
  </code></pre>
  
  <p>Both of them in the same level in the heira.
  I want to get an array that merge all the values of specific key in the heira.
  Is it possible?</p>
