Applying JSON to XML or XML to JSON policies

As you have seen throughout this chapter, there are two data formats that we have been focusing on – XML and JSON. They are the most prominent in today's API landscape. We have demonstrated the use of the map policy and how it can provide the need for custom transformations from one format to another. There may be times, however, when you just need to convert your JSON to an XML representation, or your XML to some standard JSON representation.
