You might get someone on this last willing to invent something from scratch, but really this mailing list works best if you give very specific information, such as a verbatim copy of several records worth of your data file including all the stuff you want to skip over. Usually if someone is planning on inventing an example from scratch they make a blog post which you could find via search engine. Helping you offline is also not preferred since multiple people can offer advice (or correct each other) if you keep the discussion on the list. And no, giving some of the code you have tried is indeed helpful, since it can highlight things you don't know that might seem obvious to us.
