title: Accessing JSON elements using indexes in PL/SQL
body: <p>I want to access JSON inner elements in PL/SQL.I'm using oracle 12c release 2.</p>
  
  <pre><code>    `{"widget": [
      "debug": "on",
      "window": {
          "title": "Sample Konfabulator Widget",
          "name": "main_window",
          "width": 500,
          "height": 500
      },
      "image": { 
          "src": "Images/Sun.png",
          "name": "sun1",
          "hOffset": 250,
          "vOffset": 250,
          "alignment": "center"
      },
      "text": {
          "data": "Click Here",
          "size": 36,
          "style": "bold",
          "name": "text1",
          "hOffset": 250,
          "vOffset": 100,
          "alignment": "center",
          "onMouseUp": "sun1.opacity = (sun1.opacity / 100) * 90;"
      }
  ]} `
  </code></pre>
  
  <p>In the above JSON can I navigate through by using '.' or indexes in PL/SQL?
  i.e. <code>widget[0].window.width</code> to get an inner element width.</p>
  
  <p>I want to modify/add JSON elements using navigation instead of creating new object.
  Is this Possible ?
  Thanks.</p>
