title: json parsing using spath
body: <p>I have a json log as shown below </p>
  
  <pre><code>{
  action: Get, 
  applicationName: abc,
  controller: Main, 
  ip: 123.123.123.123, 
  logLevel: INFO, 
  loggerType: abcdef, 
  machineName: windows, 
  message: {"Value":{"Data":{"Items":[{"FieldType":"abc","Value":""},{"FieldType":"abcd","Value":""},{"FieldType":"123","Value":""}],"EncryptedDocKey":"123456","Domain":"Order","Partner":"India","Carrier":"Idea"},"RequestTrackerId":"7894561230","Message":"OK"},"Formatters":[],"ContentTypes":[],"DeclaredType":null,"StatusCode":null}

  }
  </code></pre>
  
  <p>All the fields are indexed correctly. I am looking to extract json data in message element. I would like to extract FieldType,EncryptedDocKey,Domain,Partner,Carrier,RequestTrackerId in to its own fields using spath .</p>
  
  <p>any other alternative options are also welcome. Thanks you for your help. </p>
  
  <p>Tried regex but it did not work</p>
