Context copy

Hi,

I am interested whether there is possibility to copy part of the view context at once. For example if I have the following structure:

+ node1

- attribute1

- attribute2

+ subnode11

- attribute11

- attribute12

+ subnode12

- attribute121

I would like to copy the information contained in subnode11 and the attributes and nodes below it and do some work with this part of the context but I don't want to change the original.

Is this possible?

Regards,
