I was looking at a library that lets me parse comma delimited csv files without a problem, but unfortunately, I'm not allowed to make use of that library. I understand that the library probably does something similar to a string split(), but I don't quite know what kind of regular expression is being used for something that's within double quotes, but contains a comma while the line is comma delimited. for instance:
a, "b", "a,b,c", d
Should only be 4 columns. What kind of regular expression would indicate this?
Thanks for your answers in advance.
