1, I think you're likely to get better help if you asked the question more clearly. Check out How (Not) To Ask A Question, think about, and maybe clean up your post. If your post is old by then and doesn't get any answers post-cleanup, you could post a new question as a short summary of the original question and a link back to the original question.(Updates don't show up in newest nodes but they do show up in recently active threads, so updating alone might get you attention and help if you are patient.)

2, by looking at your data, it looks to me like you have csv. regex is maybe not the best option here. For my own csv parsing, I personally use Text::xSV. So I would have a look at that as well.

Hope this helps, and good luck.
