we have a requirement to transmit data from one system to another, basically it will be a complex JSON provided to us and then we should be able to forward it either in JSON string or XML.string

Now to achieve JSON to XML there are api available for ClipboardPage class in java like adoptJSONObject, getXML. but the problem is the XML generated is not desirable as it can contain pega naming convention for lists like pagelist, repeating index = 1.

How can I create a standard XML, which can be accepted outside by a non-pega application?

I am attaching an example for instance: file "whatIGet" is constructed using pega api and file "whatToAchieve" is what I want to get.

Also I wrote below function to convert JSON to XML.
 

PublicAPI tools = (PegaAPI) ThreadContainer.get().getPublicAPI();
PRThread thread = tools.getThread();
String retValue = "";
if(jsonString.length()>5){
  try{
    ClipboardPage responseDataPg = tools.createPage("$ANY", "JsonPageConvXML");
    responseDataPg.adoptJSONObject(jsonString);
    retValue = responseDataPg.getXML();
    thread.removePage(responseDataPg);
  } catch(Exception e) { 
    throw new PRRuntimeException(e); 
  }
}

return retValue;
