Im using WSO2 ESB and DDS to make an API to read data from database and finally I got this respone. How to convert this XML to Json using script mediator? Give me an example please.

<?xml version='1.0' encoding='UTF-8'?> <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
<soapenv:Body>
    <employeeCollection xmlns="http://employee.us.wso2.com">
        <employee>
            <EmployeeID>17</EmployeeID>
            <FirstName>jak</FirstName>
            <LastName>123</LastName>
            <Team>ok</Team>
        </employee>
        <employee>
            <EmployeeID>18</EmployeeID>
            <FirstName>jak</FirstName>
            <LastName>123</LastName>
            <Team>ok</Team>
        </employee>
        <employee>
            <EmployeeID>19</EmployeeID>
            <FirstName>jak</FirstName>
            <LastName>123</LastName>
            <Team>ok</Team>
        </employee>

    </employeeCollection>
</soapenv:Body>

And this is the configuration

<resource methods="POST" uri-template="/team">
  <inSequence>
     <sequence key="conf:/SendSelectWithTeam"/>
     <call>
        <endpoint>
           <address uri="https://192.168.2.165:9453/services/EmployeesDataService/" format="soap12"/>
        </endpoint>
     </call>

     <respond/>
  </inSequence>

回答1:

If you just want to convert this directly to json, you don't need to do it manually using script mediator.

You can update the out sequence of your ESB proxy (or API) like this and it will convert the response xml to json.

<outSequence>
     <property name="messageType" value="application/json" scope="axis2"/>
     <send/>
</outSequence>

See WSO2 Docs for more details.

Edit:

In your case, if you use <respond> mediator, it will bypass out sequence, and my suggestion won't work. You have 2 options to get it working.

1) Use Send mediator instead of call and respond mediators.

2) Use loopback mediator instead of respond mediator.

Please change the proxy outSequence settings in config file like below:

  <outSequence xmlns="http://ws.apache.org/ns/synapse">
   <property name="messageType" value="application/json/badgerfish" scope="axis2" type="STRING"></property>
   <send></send>
</outSequence>
