All node contents from one content type

Not yet, although it would be very simple to add this functionality.

There is perhaps a more general requirement for a flexible and scalable way of selecting content to export but I wouldn't expect to see that anytime soon.

I'll see if I can make a patch for this

Hi,

Are you currently working on this?
We also need this patch.

We will need it very quick.
If it is possible and if you are interested we could help you with the development.

greets,

Tom

I will be working on this sometime over the next few weeks. If you need it before then you should take the initiative in writing a patch

some bugfixes
