Ruby replace string with a different string

Question

I have the following string:

"test,Hello, Inc.,test2"

I want this to read:

"test,Hello Inc.,test2"

Essentially I want to convert all "Hello, Inc." to "Hello Inc.". All commas should be removed from that string only.

I am using ruby 2.0.0 and rails 4.0.0. How can I do that?

Answer 1

This should work for you specific example.

"test,Hello, Inc.,test2".gsub(/Hello, Inc\./,"Hello Inc.")

Answer 2

my_string, x = "test,Hello, Inc.,test2", 'Hello, Inc'

my_string[x] = x.delete(',')

p my_string #=> "test,Hello Inc.,test2"
