Answer 1

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">
<description/>
<target>
<endpoint>
<address uri="http://www.w3schools.com/webservices/tempconvert.asmx" format="soap11"/>
</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/">
<web:Celsius>$1</web:Celsius>
</web:CelsiusToFahrenheit>
</format>
<args>
<arg evaluator="json" expression="$.celsius"/>
</args>
</payloadFactory>
<header name="Action"
value="http://www.w3schools.com/webservices/CelsiusToFahrenheit"/>
</inSequence>
<outSequence>
<log>
<property xmlns:p="http://www.w3schools.com/webservices/"
name="TEMPERATURA_SALIDA"
expression="//p:CelsiusToFahrenheitResponse/p:CelsiusToFahrenheitResult"/>
</log>
<payloadFactory media-type="json">
<format>
"Temperatura" : {
"EnFahrenheit" : $1
}
</format>
<args>
<arg xmlns:p="http://www.w3schools.com/webservices/"
evaluator="xml"
expression="//p:CelsiusToFahrenheitResponse/p:CelsiusToFahrenheitResult"/>
</args>
</payloadFactory>
<property name="messageType" value="application/json" scope="axis2"/>
<send/>
</outSequence>
</target>
</proxy>
