Regular expression question

Ruby

I’m trying to replace all characters that are not letters numbers and
white spaces in a string. I’m getting the characters eliminated in this
case a comma but the white space is eliminated to. How do I get around
that?

string = ‘john, tony’
newTerms = string.gsub(/\W/, “”)

thanks

I think this does what you want, provided underscores are OK.

newTerms = string.gsub(/[^\w\s]/, "")

If underscores are not OK, then you’ll need to change “\w” into
“A-Za-z0-9”.

This is usually more efficient:

newTerms = string.gsub(/[^\w\s]+/, “”)

Note the “+”.
