Hello Everyone,

What is the best way to get this input

test.txt
------------------------------------------------
David | Hansson | Chicago
Obie | Fernandez | Jacksonville
------------------------------------------------

to this output:

First Name: David
Last Name: Hansson
City: Chicago

First Name: Obie
Last Name: Fernandez
City: Jacksonville

?????????????????????????

This is what I've tried so far.. I'm pretty far off I believe. Any 
suggestions would help with learning the ins and outs of Ruby (or 
programming in general)

-----------------------------
test.rb
----------------------------
myArray = []
file = File.open("test.txt", 'r+')
file.each_line do |line|
  x = line.scan(/\w+/).inspect
  myArray = x
  puts myArray
end

my output
-----------------------
$ ruby test.rb
["David", "Hansson", "Chicago"]
["Obie", "Fernandez", "Jacksonville"]


Thanks in Advance

A solution is to use printf as in the folloving code:

# test1.rb
file = File.open("test.txt", 'r+')
file.each_line do |line|
myArray = line.scan(/\w+/)
# myArray = line.split(/[\s|]+/)   Alternative solution to scan
printf("\nFirst Name: %-s\nLast Name : %-s\nCity      : %-s\n", *myArray)
end
