while input = ARGF.gets

    next unless parts.size == 13 
    timestamp   = DateTime.parse(parts[0]).to_time.to_i
    ip          = parts[7].gsub("fwd=","").gsub('"','')
    request     = parts[4].gsub("path=","").gsub('"','')

    size        = parts[12].gsub("bytes=","")
    output_line = "#{timestamp}|#{ip}|#{request}|#{status}|#{size}"
    begin

Works like a charm. Thanks!
