Rendering page as XML or JSON?

Hi, is there an easy to render a page as XML/JSON instead of HTML? For example, I would like to send back the collection as XML document. Thus, I'm looking for something similar to Rails respond_to whereas

def show

@order = Order.find(params[:id])

respond_to do |format| format.html # show.rhtml format.xml { render :xml => @order.to_xml }

format.js { render :json => @order.to_json }

end

Thanks in advance,

-Conrad

You can do something like this, replacing sixxString with your own xml
building method for something prettier, and #beXml with whatever param name
you want to kick it off...

self session currentRequest at: #beXml ifPresent: [ : it |
self session returnResponse:
(WAResponse new
contentType: 'text/xml' ;
contents: someObject sixxString readStream ;
yourself)]

If you have a json builder, it'd be similar. If there's a better way, I
don't know it.

If you make your own WACanvas subclass too you can do something like this:

response := Seaside.WAResponse new.
response contentType: 'application/atom+xml'.
response nextPutAll: '<?xml version="1.0" encoding="utf-8"?>'.
atom := SeasideAtom.AtomCanvas new.
atom context: html context.
html context document stream: response stream.
... do stuff with our new atom canvas ...
self session returnResponse: response.

Hi ALL, thanks for the information and I'll really appreciate it. At this time, I'm looking to convert a Rails application to Seaside.
