How can I view the changes made after a revision is committed and parse it for comments?

static void Main(string[] args)
{
  SvnHookArguments ha;
  if (!SvnHookArguments.ParseHookArguments(args, SvnHookType.PostCommit, false, out ha))
  {
    Console.Error.WriteLine("Invalid arguments");
    Environment.Exit(1);
  }

  using (SvnLookClient cl = new SvnLookClient())
  {
    SvnChangeInfoEventArgs ci;
    cl.GetChangeInfo(ha.LookOrigin, out ci);

    // ci contains information on the commit e.g.
    Console.WriteLine(ci.LogMessage); // Has log message

    foreach(SvnChangeItem i in ci.ChangedPaths)
    {
       //
    }
  }
}
