mpro% irb            
>> require 'lib/dot_xen'
=> true
>> puts XenConfigFile::Parser.new.simple_parse(File.read("spec/fixtures/ey00-s00348.xen")).to_s
#  -*- mode: python; -*-
kernel = "/boot/vmlinuz-2.6.18-xenU"
memory = 712
maxmem = 4096
name = "ey00-s00348"
vif = [ "bridge=xenbr0" ]
root = "/dev/sda1 ro"
vcpus = 1
cpu_cap = 100
disk = [ 
         "phy:/dev/ey00-data4/root-s00348,sda1,w",
         "phy:/dev/ey00-data4/swap-s00348,sda2,w",
         "phy:/dev/ey00-data4/gfs-00218,sdb1,w!",
         ]
=> nil
 
 
There's two parts to this
 
The .simple_parse traverses the tree and builds the representation using the models in lib/xen/ast.rb.  It'll return nil if the document is invalid.
