Regexp help needed

Hey All,

I need to parse lines that look like this:

<lines>
1 'Not qualified' 2 'Overquota' 3 'Qualified'/
1 'SSI' 2 'Mall Facility'/
1 'Real Interview' 2 'Practice Interview'/
</lines>

So I've got N sets of <<digits>><<space>><<quote-delimited-label>> on
each line. I want to grab each of the digits & labels, but I'm having
trouble w/the repetition stuff. Below is a simple script that doesn't
work--it grabs the first set, but seems to ignore the rest.

str = "1 'Not qualified' 2 'Overquota' 3 'Qualified'"
rgx = /((\d+)\s+(\'[^']+?\'))+/i
m = rgx.match(str)
unless m.nil?
   m.captures.each {|c| puts(c)}
end

Can anybody throw me a regex clue here?

Thanks!

You might want to try the scan method:

  str = "1 'Not qualified' 2 'Overquota' 3 'Qualified'"
  
  str.scan(/(\d+)\s+('[^']+')+/).each do |match|
    p match
  end

Hope that helps!

Perhaps a little something like this:

str = "1 'Not qualified' 2 'Overquota' 3 'Qualified'"
rgx = /((\d+)\s+(\'[^']+?\'))+/i
m = str.scan(rgx)
m.each do |match|
  puts match.first
end

r = %r/(\d+)\s+('[^']*')/
s = "1 'Not qualified' 2 'Overquota' 3 'Qualified'"

s.scan(r) #=> [["1", "'Not qualified'"], ["2",
"'Overquota'"], ["3", "'Qualified'"]]
