Datamapper Return Null WSO2

Question

I have an API that will return XML data, I want to use datamapper to map some data and then return it to the client, but the API after using DataMapper keeps returning null.

see below

<?xml version="1.0" encoding="UTF-8"?>
<api context="/AllAdByCRN" name="AllAdByCRN" xmlns="http://ws.apache.org/ns/synapse">
    <resource methods="POST">

        </inSequence>
        <outSequence/>
        <faultSequence/>
    </resource>
</api>

I want to map data only not converting from XML to JSON.

You have to choose XML as input and output :

<datamapper config="gov:datamapper/NewConfig.dmc" inputSchema="gov:datamapper/NewConfig_inputSchema.json" inputType="XML" outputSchema="gov:datamapper/NewConfig_outputSchema.json" outputType="XML" xsltStyleSheet="gov:datamapper/NewConfig_xsltStyleSheet.xml"/>
