Subject: can you rubyfy this?

Hi,

I often read something about code being "rubystyle" though I am not 
exactly sure what it means. Maybe someone can help me out and put the 
couple of lines below into a typical ruby style?

greets, B.

#!/usr/bin/ruby
require "rexml/document";
require "id3lib";
include REXML;
include ID3Lib;

doc = Document.new File.new("collection.nml")

entrys = doc.elements.to_a("//ENTRY")
entrys.each{|node|
     file = node.elements["LOCATION"].attributes["DIR"] + 
node.elements["LOCATION"].attributes["FILE"]
     if File.exists?(file)
         tag = Tag.new(file)
         if !node.attributes["ARTIST"]
             node.add_element "ARTIST"
         end
         node.attributes["ARTIST"] = tag.artist
     end
}
     out = File.new("test.xml", "w+")
     doc.write out
