Re: XSLT for unflattening a tree?

Hello Stu,

Yesterday I answered a post by Ed Nixon (subject line "Re: Creating
additional depth from flat structure using XSLT") which I believe is
essentially your problem, although in your case it's easier to see.
Unfortunately I seem to be suffering terrible network latency and it hasn't
appeared in my inbox yet.

Maybe you've already got it and maybe it'll still turn up. (Who knows when
_this_ message will turn up?) The short answer is that in principle, when
your source is sufficiently regular, it should be possible to do what you
need by selectively processing siblings of the headers inside the
structural elements you want to introduce in their place. This is a good
test of XSL's ability to infer and (re)introduce a structure that is only
implicit in the markup of the source document.

Have fun,
Wendell Piez
