Hi again,

sorry for the delayed response - I was traveling back from Asia.

Thank you all for the programs and comments.

I will have a look at the book.

My case is in fact more complicated than the example I provided. The
elements spanning over a boundary may be hierarchically nested. I would
like to have a stylesheet, that takes a sequence of tag names.

Your examples Vyacheslav and Praveen where very helpful for me to
understand things better. In fact, I also found a solution using the
comparators << and >> which I was not aware of when I wrote the email...

Thanks again, Josef
