[Dev] [ESB] [Payload Factory Mediator] - How to remove namespaces

[Rajkumar Rajaratnam]

Hi,

I am trying to use Payload Factory Mediator to transform a request.

*Original request's body*

<soapenv:Body>




*<m0:getQuote xmlns:m0="http://services.samples <http://services.samples>">
<m0:request><m0:symbol>IBM</m0:symbol></m0:request></m0:getQuote>*
</soapenv:Body>

*What I want*

<soapenv:Body>


*<GetQuote><symbol>IBM</symbol></GetQuote>*
</soapenv:Body>

*My Synapse configuration*

      <in>
         <payloadFactory media-type="xml">
            <format>
               <GetQuote>
                  <symbol>$1</symbol>
               </GetQuote>
            </format>
            <args>
               <arg xmlns:m0="http://services.samples";
                    evaluator="xml"
                    expression="//m0:symbol"/>
            </args>
         </payloadFactory>
         <class name="org.wso2.esb.mediator.ProtoBufMediator"/>
      </in>


*But what I get in the transformed message's body is*

<soapenv:Body>
<GetQuote *xmlns="http://ws.apache.org/ns/synapse
<http://ws.apache.org/ns/synapse>"*>
<symbol>IBM</symbol>
</GetQuote>
</soapenv:Body>

*My intention is not to have any namespaces inside message body. How can I
achieve this?*



I tried removing namespace inside my custom mediator using,

*mc.getEnvelope().getBody().getFirstElement().getAllDeclaredNamespaces().remove();*

It gave the following error when I send request from my client.
