Remove double quotes from string

Question

I\'m trying to grab data from a MySQL database and use Ruby to reformat it into a flat text file. Some of my MySQL data contains double quotes like so:

<

Answer 1

You could use something like:

text = 'Matthew "Matt" Perry'

text.tr(%q{"'}, '|') # => "Matthew |Matt| Perry"

text = "Matthew 'Matt' Perry"
text.tr(%q{"'}, '|') # => "Matthew |Matt| Perry"

Answer 2

This will do it if you don't want to modify s:

new_s = s.gsub /"/, '|'

If you do want to modify s:

s.gsub! /"/, '|'

Answer 3

It removes doublequotes. You can see them in IRB or when using p only because string are being showed for you in these cases in nice form, allowing you to see, that they are strings.

irb> 'Matthew "Matt" Perry'.scan(/'(.+?)'|"(.+?)"|([^ ]+)/).flatten.compact
=> ["Matthew", "Matt", "Perry"]

In real, they already don't have doublequotes.

irb> puts 'Matthew "Matt" Perry'.scan(/'(.+?)'|"(.+?)"|([^ ]+)/).flatten.compact
Matthew
Matt
Perry
=> nil

And to replace doublequotes with dash, you may use .tr:

irb> 'Matthew "Matt" Perry'.tr '"','|'
=> "Matthew |Matt| Perry"

Answer 4

Other choices are:

s.tr! '"', '|'
s2 = s.tr '"', '|'
