Hi Pablo Here is a quick solution. However, it not treat the incorrect input data, ie it requires, however, correct input, otherwise it will collapse ...

Hi Pablo, I am sending still slightly modified version (use local variables and better typographic output). It use of much variables, but at least it is clear how it works. For solution occurred me to use parsing function that I have been defined in the library, so that it can be successfully used.

Hi,
What about "Test;11/11/1999" ... ;-)
Hi Peter, all dates start from this year :-). Pablo -- http://www.ousia.tk
;-) Thanx Peter. I'm too not thought about solutions :-). I was so focused to mined data from a CSV file, and I've not think much about the appropriate algorithm. I love attentive and thoughtful people (although often I'm not alone such) Maybe I corrected in a subsequent e-mail properly. One more thanx.

Hi Pablo. Peter pointed out an error in my solution. Thanks Peter! His message but pointed out that in fact is not the task as simple as it seems at first glance. In fact, a lot depends on what target group for those you solve a problem resp. whether e.g. date of birth of persons. What does it mean 03/01/00? It means 1/3/1900? Or does it mean 01/03/2000? Particular job you have to deal specifically separately. It occurred to me yet following solution that respects the current year as the year when he could anyone born. E.g. 19/12/14 means a newborn soul (ie. In fact, 12/19/2014), while 01/02/15 mean old man ie. in fact 01/02/1915. For the specific case you have to modify or create the solution separately. Greetings Jaroslav Hajtmar Here is new minimal example: \usemodule[scancsv] \def\ddmmyyyy#1#2#3{% #1 - date, #2 - old separator, #3 - new separator \startlua local parsedate=thirddata.scancsv.ParseCSVLine('#1','#2'); local day=tonumber(parsedate[1]); local month=tonumber(parsedate[2]); local year=tonumber(parsedate[3]); if (year<100) then % when is only two digits year format then if year<=14 then % it is very young person year=year+2000 else % this person has more than one hundred years year=year+1900; end; end; tex.print(day..'#3'..month..'#3'..year); \stoplua } \unexpanded\def\lineaction{ \Name\ born \Date\quad (\ddmmyyyy{\Date}{/}{.\\,}) \\ } % Content of CSV file: % Name;Date % ME;11/10/14 % You;05/02/14 % He;15/02/2014 % She;03/03/12 % It;03/03/14 % A;11/11/1999 % B;01/2/1964 % C;02/3/23 % D;03/4/64 % E;04/5/00 % F;05/6/01 % G;05/7/15 % H;05/7/1915 % Test0;1/2/00 % Test1;1/2/01 % Test2;1/2/02 % Test3;1/2/03 % Test4;1/2/04 % Test5;1/2/05 % Test6;1/2/06 % Test7;1/2/07 % Test8;1/2/08 % Test9;1/2/09 % Test10;1/2/10 % Test11;1/2/11 % Test12;1/2/12 % Test13;1/2/13 % Test14;1/2/14 % Test15;1/2/15 % Test16;1/2/16 % Test17;1/2/17 % Test18;1/2/18 % Test19;1/2/19 % Test20;1/2/20 \setheader \setsep{;} \setfiletoscan{mail.csv} \starttext \filelineaction \stoptext Dne 18.12.2014 19:07, Pablo Rodriguez napsal(a):
