I am trying to look for a a given string in = a text and once i find the
string
I want to be able to store a string that comes after it.

For example I would look for a String "JUNE" and once I find &quo= t;JUNE" in
the text
I want to store the string that follows JUNE in a variable x. This
string should be 7 characters. So if the text has "JUNE seventh 2012&q= uot;. I
want to be able to store the string seventh in a variable x. Such that
puts x will print seventh on the screen.

This is what I have so far but this only prints the string that I am
looking for. I would like to be able to print the string that comes
after the string I am looking for.

file_names =3D ['Document.txt']

file_names.each do |file_name|
text =3D File.read(file_name)

x =3D text.scan("June")
puts x

end

please advise.

You need a regu= lar expression with a capturing group.

Cheers

robert
