RSS FEED default servlet for every page

Hello guys,

I want to create a RSS component for every page.

Iam not sure I am thinking the right way.

I want to write a servlet which returns xml of the actual node and give the title, the description and the modify date as RSS-XML to the user. But I don't know how to write one servlet which is called for every page under:

• example.com/examplepage.rss.xml
• example.com/examplepage1.rss.xml
• example.com/examplepage2.rss.xml
• ...

the servlet should be callable as default for every page.

How can I achieve this? Can someone point me in the right direction.

up to now I have the following servlet which renders for a specific resoureType but I am searching for a wildcard or something to call it for every path or specific root path and all of its children.

@SlingServlet(resourceTypes = "geometrixx/components/homepage",
   selectors = "rss",
   extensions = "xml",
   methods = "GET",
   metatype =true)
public class SimpleServlet extends SlingSafeMethodsServlet {
   @Reference
   private Repository repository;
   @Override
   protected void doGet(final SlingHttpServletRequest req,
  final SlingHttpServletResponse resp) throws ServletException, IOException {
  resp.setContentType("application/json");
   String keys[] = repository.getDescriptorKeys();
   JSONObject jsonobject = new JSONObject();
  try {
  jsonobject.put("test", "testvalue");
   } catch (JSONException e) {
  e.printStackTrace();
   }
  resp.getWriter().println(jsonobject.toString());
   }
