Thanks to everyone. Parenthesized alternative works, but I found a
solution based on character classes:

\\(<author>[[:print:][:space]]*?</author>\\)

So long, it works. It will help me to get rid of nested groups.

Yes, but this is the same hack I wanted to avoid: taking a character
which is not supposed to be found inside the tag and matching anything
except for this character. What if this character appears in some
author's name? What if Prince changes his name again? :)

Is there a comparison of various regexp tools' efficiency: are
character classes fast enough? would parenthesized groups be faster?
or character alternatives (like that [^±])?

Thank you.
