ATG REST Webservices - XML response

Question

Hi,
I need to build an ATG REST component which returns the response in XML format and it is done.
The question that I have here is that, in the XML response, the response XML that I exactly want is embedded inside <atgResponse>..</atgresponse> tag.
For ex:
The actual response that I need in the client side.
<address>
<address1>123 Main st</address1>
<address2>Apt 12</address2>
<city>Attleboro</city>
<state>MA</state>
<zip>02073</zip>
</address>
The response that I am getting back from my REST component:
<atgResponse>
<address>
<address1>123 Main st</address1>
<address2>Apt 12</address2>
<city>Attleboro</city>
<state>MA</state>
<zip>02073</zip>
</address>
</atgResponse>
Do I need to handle the logic of taking the xml that I needed from the XML response that is coming from my REST component, in the client side only?
The other concern that I have is, I do not want my client application to know that I am using ATG REST services.
Appreciate any help in this.
Thanks in advance,

I have not tried it but I would probably try to extend XMLOutputCustomizer and override sendToOutputStream(Object pDocument, DynamoHttpServletResponse pResponse) method as per the requirement. Here pDocument would actually be an instance of org.dom4j.Document so you can access and update its root element. You can also process other output elements as well by iterating through the elements and when done write the Document object through org.dom4j.Document to XMLWriter. Something like below:
Document doc = (Document)pDocument;
//process Document object
org.dom4j.io.XMLWriter writer = new org.dom4j.io.XMLWriter(pResponse.getWriter(), createDefaultOutputFormat());
writer.write(doc)Override the default /atg/rest/output/XMLOutputCustomizer configuration to refer your class and see if it serves your purpose.
