[xsl] climbing to the root element

["Ke'tszeri Csaba" <csaba@xxxxxxxxxxx>]

Hello!

My xml doc has a structure like the one at the end of this letter.
If an item has a nametype=multiple, then I have to
prefix their nametext with their containing item nametext.
I have to repeate it as many times as multiple type items cascaded
together, plus the one item with simple type above them.

The expected output is this:
a
b
bi
biv
bj
c

There are several other container elements between the simple and
multiple type items, so i can't predict how deep I am, and how far
should i look for the parent item.

My real problem is that I can't make a recursive function to go back
to the / direction.

Could you give me some ideas?

Thank you!

Csaba
