Das wird dann schnell knapp, wenn ich Position 27 haben will :) Leider ist das Feld, wo ich den regulären Ausdruck eingeben muß vielleicht 30 Zeichen lang oder so.

Here is the example for getting field number 13 without the quotation marks: <code>(?:\"[^"]*\",){12}\"([^"]*)\",.*</code> I forgot to mention that the CSV line is part of a bigger file which means there can be lines before and after this CSV line that do not contain any relevant data :) Thanks a lot to x who solved this issue in a second!
