I realised I had a special-purpose filter for CSV → XML for my bank accounts that I could convert to ixml, so here goes:


csv: row*.
row: v*-",", nl.
v: quoted; unquoted.
-quoted: -'"', q*, -'"'.
-q: ~['"']; '"', -'"'.
-unquoted: ; ~['",'; #a; #d], c*.
-c: ~[","; #a; #d].
-nl: (-#a; -#d)+.


Example taken from the Wikipedia page on CSV:


Year,Make,Model,Description,Price
1997,Ford,E350,"ac, abs, moon",3000.00
1999,Chevy,"Venture ""Extended Edition""","",4900.00
1999,Chevy,"Venture ""Extended Edition, Very Large""",,5000.00
1996,Jeep,Grand Cherokee,"MUST SELL!
air, moon roof, loaded",4799.00


Result:
