How can I get the response body in WSO2 ESB - json

Question

The response format like this in WSO2 ESB：
<testresponse xmlns="http://abcd/service">
<cookie>yummy</cookie>
<product>YM11</product>
<place>US</place>
</testresponse >
But I just want the body, how can I do?
<cookie>yummy</cookie>
<product>YM11</product>
<place>US</place>
The goal is to transform the xml in a JSON object like the following
{
"cookie": "yummy",
"product": "YM11",
"place": "US"
}

You can use the payloadFactory
<payloadFactory media-type="xml">
<format>
<jsonObject>
<cookie>$1</cookie>
<product>$2</product>
<place>$3</place>
</jsonObject>
</format>
<args>
<arg evaluator="xml" expression="//cookie"/>
<arg evaluator="xml" expression="//product"/>
<arg evaluator="xml" expression="//place"/>
</args>
</payloadFactory>
But as already commented you need an enclosing element if not your xml will simply not be valid. If the goal is to output Json this element should be called jsonObject (find more info here : https://docs.wso2.com/display/EI600/JSON+Support).
If you don't need XML the best approach would be to directly build your json object
<payloadFactory media-type="json">
<format>
{
"cookie": $1,
"product": $2,
"place": $3
}
</format>
<args>
<arg evaluator="xml" expression="//cookie"/>
<arg evaluator="xml" expression="//product"/>
<arg evaluator="xml" expression="//place"/>
</args>
</payloadFactory>
