body: <p>I want to know if it's possible to validate a JSONPath expression.</p>
  
  <p>My JSONPath is <code>$.phoneNumbers[:1].type</code></p>
  
  <p>And my json is as follows:</p>
  
  <pre><code>{      
    "phoneNumbers": [
       {
         "type"  : "iPhone",
         "number": "0123-4567-8888"
       },
       {
         "type"  : "home",
         "number": "0123-4567-8910"
       }
    ]
  }
  </code></pre>
  
  <p>I want to know if I am using the right/valid JSONPath expression.</p>
