xsl: how to select slice of tree regarding the node position

[pietro abate <pietro.abate@xxxxxx>]

Hi,
I've a tree like

 |---B
 |---B |---D
 |---C-|---D
A|---B    (*)
 |---C-|---D

and I would like to trasform in a tree like
       |---B
 |---H-|---B
 |
 |---H-|---newC
 |
 |     |---D
A|---H-|---D
 |     |---newC
 |
 |---H-|---B
 |
 |---H-|---newC
 |
 |---H-|---D
       |---newC
In other words I want ot group the B, and split the C, but in accord
with the position in the original tree;
So I don't know how to select, for example, the B(*) because it's a B
and because it's between two C.If I try to make a template to select
all the B I lose the information about the position, an if I try to
select all the C I lose the possibility of group _all_ the previous B.

Suggestion ?

pietro
