title: parse a yml file which has . in key using shyaml
body: <p>I have the following yaml file - </p>
  
  <pre><code>ex1:
    name: abcd
  ex.2:
    name: xyz
  </code></pre>
  
  <p>When I trying doing -</p>
  
  <p><code>cat a.yml| shyaml get-value ex.2.name</code></p>
  
  <p>It throws an error -</p>
  
  <p><code>Error: invalid path 'ex.2.name', missing key 'ex' in struct.</code></p>
  
  <p>I tried escaping the . using \ but couldn't get it to work. Is there a way I can parse this yaml file? I would like to avoid writing shell scripts for this.</p>
