What is the point of having parenthesised groups in the regex if you
are interested only in the whole match?
Other comments:
(1) raw string for improved legibility
ru'(?u)\b([á-ñ]{2,}\s+)([<<"][Á-Ñá-ñ]+)(\s*-?[Á-Ñá-ñ]+)*([>>"])'
(2) consider not including space at the end of a group
ru'(?u)\b([á-ñ]{2,})\s+([<<"][Á-Ñá-ñ]+)\s*(-?[Á-Ñá-ñ]+)*([>>"])'
(3) what appears between [] is a set of characters, so [<<"] is the
same as [<"] and probably isn't doing what you expect; have you tested
this regex for correctness?

I can't imagine how "not a programmer" implies "interested to know if
there is a more elegant way". In any case, explore the correctness
axis first.
