Hi, Is it possible to get the value of "output:media-type" through QueryProcessor? I am currently trying to use BaseX as a view renderer for a Spring MVC application. The view is rendering fine using embedded BaseX. However, I can't figure out how to get the "output:media-type" value from the XQuery so that I can set the response header during runtime. I can set the content-type through the controller in Spring. But I would rather not have to do it in two separate places. Below is the relevant code snippet from the view renderer. try(QueryProcessor proc = new QueryProcessor(query, context)) { Iter iter = proc.iter(); //response is HTTPServletResponse response.setContentType(????); try(Serializer ser = proc.getSerializer(response.getOutputStream())) { for(Item item; (item = iter.next()) != null;) { ser.serialize(item); } } } Any suggestion? Thanks Andrew
