Thanks Perry!

I suppose this was obvious to everyone, but I really didn't see it in
the documentation -- or even an example of usage.

Thanks again!
Mark

I've been trying to do some simple searches like:
(query-replace-regexp "<span[:ascii:]*?</span>+" "test")
or even the simpler
(query-replace-regexp "[:ascii:]*" "test")
and not getting anywhere. Emacs just looks for the characters ":acis"
-- not for the POSIX character set of all ASCII characters. Trying it
with other sets also got me nowhere. These character classes are
listed in the Emacs documentation -- is there a trick to getting them
to work?
Looks like you need two sets of brackets?
[[:ascii:]]*


you may understand the inner bracketed-form like an equivalent to "a-zA-Z"

you may write for example

[[:ascii:]ÄÖÜaöü]*

in order to cover german umlauts too
