Sorry, I made a mistake with my answer above. Instead of using xargs (which
was exactly the same as your method - actually)
Use find to make sure ruby gets a unique file each time:
find *.xml -exec ruby -n -e 'puts ($FILENAME + " " + $..to_s + "" + $_) if
/Open/' {} \;
--still doesn't help on Windows though

Instead of trying to do this in a one-liner, save the following as a file:
ARGV.each do |filename|
  File.open(File.join(File.dirname(__FILE__), filename)) do |file|
    while line = file.gets
      puts (filename + " " + $..to_s + "" + $_) if line =~ /Open/
    end
  end
end

And then run:
ruby <filename> *.xml

Hopefully that helps
