I have an issue as I would like to sort my output kml file in a hierarchical way. I have for the moment sort by country (alphabetic, 1order), by year(numeric,2 order) and I would like to sort now by month but not in an alphabetical way, but from jan, feb, mar...... That means in a monthly order. I have got the value in a field of my shapefile, but I do not know how to display it correctly by month.
Does anybody know the way to do it ?
Thanks in advance!
