Christian,

When you need to apply regex matching to text that crosses node boundaries,
in the past two approaches have been proposed:

(a) create a string in which the node boundaries are represented by some
recognizable textual markup (you could use saxon:serialize()), then apply
the regex processing, then reinstate the node structure (e.g. by using
saxon:parse()).

(b) do a deep copy, while processing each of the text nodes to replace the
significant features (such as end of sentence) by nodes (e.g. an
<end-of-sentence/> element). Then apply positional grouping techniques to
transform this into your target structure.

Neither is particularly easy, I'm afraid.

This is because (yay) this requirement introduces an overlap problem. 
Indicators (in this case, punctuation) within text content are being 
taken to be structural features, which may overlap with other 
structures already in place.



Cheers,
Wendell
