Question

I want to fetch all the strings between _(” “) from my file.

How may i fetch that?

Answer 1

Assuming there are no quotation marks nested within the string you’re looking for, you want to load the file into a string

str=File.read("/path/to/file")

Then scan the string using a regular expression. The following regular expression should do the trick. It looks for the characters _(" (the open parentheses here is escaped, because parentheses have a special meaning in regular expressions). The next parentheses starts a capturing group (so that the text of the string will be stored in the special variable $1. Then it finds a string of consecutive characters until the first quotation mark. Then it ends the capturing group (with an unescaped close parentheses) looks for a ") to finish the expression.

/_\("([^"]*)"\)/

To use it

str.scan( /_\("([^"]*)"\)/ ) do
  puts $1
end
