Do you mean using submatch(0) to retrieve what /\d\+< actually matched
in the current iteration?

So far this seems to be the only way to retrieve the string that a regex
actually matches... alas, as per the :help submatch vim manual...
submatch() can only be used in the context of the replacement part of
a :substitute command - which is not what I had in mind.

Just curious. I gave up on the idea of using vim in this instance and
wrote a ~10 lines python script that rewrites the file... adding the
links where relevant.

Always try to eat off of a clean plate when you can. The index file as
tidied up by yours truly was nice and clean to start with... My little
script only created ~10 faulty <a href= > links out of the 6,000+...
which took c. 10 minutes to edit.

All the same & just for the hell of it... doing it in vim would have
been more satisfying.

So if you could afford the time... could you explain the vim solution
you had in mind? I'm still interested.

Thanks,

CJ
