RE: [xsl] Preceding sibling selction

Oh dear, you are really struggling with the basics.

You have a recursive structure in which BODY elements are nested inside BODY
elements. This is absolutely the kind of structure that XSLT was designed
for, with its processing model based on recursive descent using matching
template rules. Typically you write a template rule for every element, which
calls apply-templates to process its children using the template rules that
best match the children. I showed you how you could have two template rules
matching different kinds of BODY children based on examining their
properties, or in this case the properties of their parent elements.

The problem is that you aren't understanding the answers you are being given
because you haven't learned the basic concepts of the language. You won't do
that by throwing questions at a forum and hoping for enlightenment in the
answers. Spend some time with a good book (that's always what I do when
trying to learn a new technology). Work through the introductory chapters
carefully and study the examples. Then when you have a specific problem,
come back here with it, and there's a reasonable chance that you will
understand the answer.
