Split a string ignoring quoted sections

Question

Given a string like this:

a,\"string, with\",various,\"values, and some\",quoted

What is a good algorithm to split this based on

Answer 1

What if an odd number of quotes appear in the original string?

This looks uncannily like CSV parsing, which has some peculiarities to handling quoted fields. The field is only escaped if the field is delimited with double quotations, so:

field1, "field2, field3", field4, "field5, field6" field7

becomes

field1

field2, field3

field4

"field5

field6" field7

Notice if it doesn't both start and end with a quotation, then it's not a quoted field and the double quotes are simply treated as double quotes.

Insedently my code that someone linked to doesn't actually handle this correctly, if I recall correctly.
