@Timur: a non-word character in the target isn't
required, but any multi-word instances that happen to contain non-word characters needs to be included by the search, too. (also... that expression crashes my Sigil 5.1
)
I've yet to find an instance where Jellby's expression skips something that I wanted included. And I've given it a hell of a workout so far.
This is the non-beta version of what is now working outstandingly well for me.
Code:
(?U)<span class="italics">[^<]*\s.*</span>
