Simple code

Ruby

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?

Try “if md.nil?” instead.

else
puts md

puts md, md.post_match

if md

puts line

Try this:

re=Regexp.new(’^\s+[A-Z]’) #match start of line only
…
…
while line = gets
md=re.match(line)

if md
puts line

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

puts ’ {| class=“wikitable”

while line = gets
puts line if line =~ re
