This shouldn't be a problem, but I need to understand more about what
you're aiming for. Do you think you could give a bit more detail about
what you want this generic solution to do?

Obviously you've got a source document that contains some data, which
contains nested structures - you want this to work with all XML
documents, so the names of the elements in that document don't matter,
and the structure might change from XML document to XML document.

You must have some way of indicating the nodes that you want to pull
out from the source document - how do you intend, or want, to do that?
Do you want a general stylesheet that you import into a more specific
stylesheet that selects the nodes you want to retain? How does the
stylesheet that you want help with fit into the bigger picture of what
you're doing?

Finally, there's the question of what you want from the result. You
want the selected nodes, obviously; I think that you want their
ancestors as well; and it seems like you want certain other nodes in
addition. How can you tell which nodes you want and which you don't?
In the example you gave, what's special about the volume and number
elements? Is it that they're children of an ancestor *and* don't have
child elements themselves? In the general case, what are the
characteristics of the nodes that you want to copy as opposed to those
that you want to ignore?

If you can describe what you want, I'm sure that we can help you
achieve it.

Cheers,

Jeni
