I'm an amateur at regular expressions :-(
I know I can search for...
'[a-zA-Z0-9\+\-\.\*\/\(\)\_]+'
and my editor (UltraEdit) will highlight...
'some_text_characters_and_math_operators'
I want to do a replace operation such that I get...
(In other words just change the opening and closing characters)
How do I do that?
(UltraEdit supports Perl, Unix and their own flavor of regular
expression language.)
Thanks!

Stormy on the East Coast today... due to Bush's failed policies.

Depending on what regex compiler it uses, either this:
or this:
\
By default, regex's match characters as-is, but if the compiler
interprets a character as special (like + or ]) you put a backslash in
front of it to mean "match this character as-is".
Note that some regex compilers do the opposite for some characters;
for example Emacs's () are regular characters, but \( and \) are
special grouping operations. So either read the manual, or just try
both ways.
Both approaches replace 'desired_text' with
:-(
I need to retain the desired_text.

I'm learning. I have several cookbooks, but I think I need a good
introductory text.
