Hi Aditya,
You can use XSLT mediator [1] for this purpose. You could pass your
current response
from AggregateMediator to an XSLT mediator and build the required response.
I have tried with the attached XSLT and received below output.
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
<jsonObject>
<id>1</id>
<make>TAHB</make>
<children>
<kid>1</kid>
</children>
<children>
<kid>2</kid>
</children>
<name>Home</name>
<area>5000sqft</area>
<children>
<id>2</id>
<make>Tonda</make>
<name>Car</name>
<model>Tmaze</model>
</children>
<children>
<id>3</id>
<make>Tamsung</make>
<name>Mobile</name>
<model>S8</model>
</children>
</jsonObject>
</soapenv:Body>
</soapenv:Envelope>
