escaping special characters.


I have to remove the speial symbols from list of names. But I want to
remain the dot(.) in the name itself.
I use"

It is sibstituting with hyphen(-), including dot(.) also. I want to
remain dot. How to do it. please help.

I would suggest building up the expression a bit at a time and making
sure you understand what the result at each stage is and why. You
should them be able to work out what is going wrong. Then if you
cannot get a particular operation to work as you expect and do not
understand how to fix it ask for help on that particular bit.
