That's tough. I can't think of a one-time expression that will accomplish that.
Seriously... I'd change all occurrences of
Code:
<p class="calibre1">•</p>
to something else: like
Code:
<p class="calibre1">_@</p>
Then you can clean up all the rest of the • characters and change the scene breaks back after you're done.
WS64's two pass suggestion could work too (and wouldn't require altering the existing scene breaks).
EDIT: Never mind the alternate suggestions if you already worked around the problem. I understand looking for that "
one regexp to bind them all", but I'm just not sure it's worth an extended quest for this one.
