Please see How do I post a question effectively?. In particular, note how the whitespace in your posted input has become mangled. This is because you did not include <code> tags. It's hard to help you code/debug if we see something different than what you see. Markup in the Monastery or Writeup Formatting Tips may be helpful.

For some sample code for list comparisons, which is close enough to be informative for your use case, see How can I tell whether a certain element is contained in a list or array? and/or How do I compute the difference of two arrays? How do I compute the intersection of two arrays? in perlfaq4.

You may also want to use a pre-rolled parsing solution, such as Text::CSV.

Have you actually written an code we can look at? Even if it doesn't work, it's very helpful in understanding how you are thinking.
