hi

#!/usr/bin/ruby -w
re=Regexp.new('\s+[A-Z]')
puts " {| class=\"wikitable\"

-

Table -- put your title here

-"

while line = gets
md=re.match(line)
  if md =~ nil
  else
  puts md
  end
end

I input the text as

   COM - Commercial
   EDU - Educational
   GOV - Povernment
   NET - Network
   MIL - Military
   ORG - Non-profit organisations

and I get the result as

{| class="wikitable"

-

Table -- put your title here

-

nil
   C
   E
   G
   N
   M
   O
nil

How do I prevent the nil appearing?
How do I access each matchdata with the postmatchdata on each line?

while line = gets
md=re.match(line)
  if md =~ nil

Try "if md.nil?" instead.

  else
  puts md

puts md, md.post_match

re = /\s+[A-Z]/

puts ' {| class="wikitable"

-

Table -- put your title here

-'

while line = gets
  puts line if line =~ re
end
