But if we analyse the logic behind your argument we get "an error in analysing the requirement implies that all technical solutions resembling it must be wrong" - which I would hope reveals why I disagree with the argument, while remaining open-minded about variety of possible solutions.

Your regex still doesn't do what the OP is asking for, namely to split the line into the comma-delimited fields, taking care not to split on the comma if it is within quotes. Nor will it handle tohe given data correctly (tip: there's a telephone number which is not part of the address). Do try to read what other people have written more carefully, especially if it has been explicitly pointed out to you.

As for your other remark, this is an area where it's unwise to use regular expressions because it's rather complicated to come up with a robust solution (take a look at Mastering Regular Expressions, it handles this subject in some detail) and there are perfectly well-developed solutions for parsing CSV files in CPAN, which have already been pointed out by others.


Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -- Brian W. Kernighan

Well, the OP didn't in fact ask for that, although I can agree now that they probably should have done.
