Hello Fraser,
Here are some explanations about the Transformer filter with a sample code.
Application application = new Application(component.getContext()) {
@Override
public synchronized Restlet createRoot() {
Router router = new Router(getContext());
Representation xsltRepresentation = <your xslt
transformation as a StringRepresentation, or FileRepresentation,
etc.>;
Transformer transformer = new
Transformer(Transformer.MODE_RESPONSE, xsltRepresentation);
transformer.setNext(MyResource.class);
router.attach("/", transformer);
return router;
}
};
As a filter, the Transformer filter applies on hierarchy of Restlet or
on a Resource (specified by the setNext() method). According to its
mode, (Transformer.MODE_REQUEST, or Transformer.MODE_RESPONSE), the
filter applies an XSLT transformation on representations (conveyed by
the request or by the response). In the sample code provided above,
all representations returned by MyResource will be transformed with
the xsltRepresentation. With the MODE_REQUEST, the transformation
applies on all representation conveyed by the request (a POST request
for example).
Having said that, I'm not sure to understand clearly your problem.
Could you tell us where do you retrieve your XML representations from
the eXist database. In the RFQResource#HandleGet method?
best regards,
Thierry Boileau
