I have this expression:
channelName = rhash["Channel"].gsub("'", " ")
it works fine. However, I can only substitute 1 character with it. I want to add a few more characters to substitue. So I tried the following:
channelName = rhash["Channel"].gsub(/[':;] /, " ")
This did not work, that is there was no substitution done on strings and no error message. I also tried this:
channelName = rhash["Channel"].gsub!("'", " ")
This lead to a string that was blank. So absolutely not what I desired.
I would like to have a gsub method to substitute the following characters with a space in my string:
' ; :
My questions:
How can I structure my gsub method so that all instances of the above characters are replaced with a space?
What is happening with gsub! above as its returning a blank.
Your second attempt was very close. The problem is that you left a space after the closing bracket, meaning it was only looking for one of those symbols followed by a space.
Try this:
channelName = rhash["Channel"].gsub(/[':;]/, " ")
