For example, you can extract data using JSONPath and then apply a SpEL processor to the extracted data. Assume you have a service that resolves to the following JSON response.
   "name": "Joe Bloggs",
   "city": "London",
   "country": "UK"

You have a requirement to extract the country and transform the value to United Kingdom whenever the current value is UK. You would add a JSONPath processor to select the country followed by a SpEL expression to transform the selection, as shown in the following figure.

Reusing chained processors

You can make a chained processor reusable by creating it as a named value processor. Then you can construct more complex processor chains made up of those named value processors.
