In attempting to improve the CSV parser based on comments, I have the following code that's attached. I'm having a heck of a time getting the double quotes = an escaped quote thing to work. There is some commented out code which was my last attempt. As it stands the code works, minus the escaped quotes. Remove the comments and it just hangs.
I haven't looked at the code, but it occurs to me that the issue may be to do with lookahead. If you're in a quoted string, then "" means a quote character in the string, but ", or "\n or "<EOF> mean end of cell. You can't tell which is which until you read the final character; specifically, you can't tell if the string has ended until you read the newline or EOF at the end of the line. Does that help? --KW 8-)
