Well, sigh ..... This brings us back to the "fun" of parsing CSV
files. See some long thread(s) from a few months ago.
Given an input line like
"Tweedly, Alex", "id1","alex at tweedly.net"
this script, like the other ones given in this thread, will give a
result that might be a surprise.
The "obviously correct" answer that many would expect is
> name = Tweedly, Alex
> id = id1
> email = alex at tweedly.net
but this scripts would get
> name = Tweedl
> id = lex
> email = id1
The quotes in the input file do NOT hide the commas, and so every comma
would be an item delimiter.
This may not be an issue in this particular case, depending on what
constraints Paul knows of in the input data. If that possibility needs
to be accounted for, you need to either parse char by char, or use the
fast but rather opaque "split and alternate" method from one of the
earlier threads, at
Also, there are some email addresses that can ONLY be properly
represented by including quotes because they contain commas. For instance
"any name you might, perhaps, like" <alex at tweedly.net>
is a valid email address.
This form of valid email address might suffer from trying to store in
this format, or at least might need to choose one or other of the
various ways CSV files handle included quotes (either doubling them
within the field, or escaping them with something like '\').
