Subject: multiple alternatives regexp question

Message-ID: <E1Ae2MV-0007nZ-00@lab45.ma.utexas.edu> (raw)

I am interested in a regexp that I think should be written
like this (for inclusion in a program):
"\\([[:lower:]]\\|[[:digit:]]\\|A\\)\\([A-Z]\\)"
In other words, a lower case letter, or a digit, or an `A',
followed by a capital letter.
Unfortunately, when I search and replace like so:
(let ((case-fold-search nil))
(while (re-search-forward "\\([[:lower:]]\\|[[:digit:]]\\|A\\)\\([A-Z]\\)"
nil t)
(replace-match (concat (match-string 1) " " (match-string 2)))))
on something
like
ProofOfPropertiesOfTraceOfAMatrix
I get back
Proof Of Properties Of Trace Of AMatrix
^
(Note that if you run the above code on the output string, it will
make a space in the appropriate place!)
Why is the `A' not being treated the way I want the first time
around?
