Hi All,

As a first exercise with Ruby, I am going through the Pickaxe book and
creating a jukebox. I haven't even tried to create an array of songs
yet, because I got distracted and wanted to work this out. I am trying
toi feed in the data from my iTunes xml file to it to get the data, I
can get it to work if I delete most of the xml file, but when it's 5-6
gig, rexml just seems to die. I have vaguely heard that stream parsing
may be the answer, but am totally unaware of how to use it.

here is the code in my xml reading program so far (saample.rb basically
just creates song items):

require 'rexml/document'
require "sample.rb"

doc = File.open("iTunes.xml")
xml = REXML::Document.new(doc)
name = "name"
artist = "artist"
time = 60
cnt = 0
xml.elements.each("//key") do |k|
if k.text == "Name" then
name = k.next_sibling.text
cnt += 1
end
if k.text == "Artist" then
artist = k.next_sibling.text
end
if k.text == "Total Time" then
time = k.next_sibling.text.to_i/1000.0
song = Song.new(name,artist,time)
song.to_s

end

end
puts cnt
