Subject: Gsup with variable when replacing

Hi people,

I'm trying to transform this kind of line :
123232321
FOOFOOFOO
..
2431232
BARBARBAR

to
<number>123232321</number>  (actually XML)
<number>2431232</number>
So I have coded this script
File.open("D:/digisoft/1b.txt","r") do |f2|
  while line = f2.gets
       f3 = line.gsub!(/\d+$/,'<number>\1</number>')
       puts f3
  end
end

but Ruby doesn't seem to apraciate .. I search example and I found
that variable as $1, \1, &$ could do this job but i can't get it
works.
How can I get the match of my regexp and add <number> blocks please ?

thanks you
