Try payload/enrich mediators ..

Answer 2

you could use the payloadfactory mediator in ESB 4.8.1, take this xml as an example. you need to do some changes :-) but it´s an start:

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="JsonToXMLProxy"
       transports="https http local"
       startOnLoad="true"
       trace="disable">

      </endpoint>
      <inSequence>
         <log>
            <property name="TEMPERATURA_ENTRADA" expression="json-eval($.celsius)"/>
         </log>
         <payloadFactory media-type="xml">
            <format>
               <web:CelsiusToFahrenheit xmlns:web="http://www.w3schools.com/webservices/">

            </format>
            <args>
               <arg evaluator="json" expression="$.celsius"/>
            </args>
         </payloadFactory>
         <header name="Action"

                      expression="//p:CelsiusToFahrenheitResponse/p:CelsiusToFahrenheitResult"/>
         </log>
         <payloadFactory media-type="json">
