[mapserver-users] KML reading through OGR

[alok mathur]

Hi Lars,

I want to create a styling for each placemark  in .map file. Means If i
have a KML containing one folder with multiple placemarks as shown below. I
want to create a .map file which will contain style for each placemark.
What if i have the same names of placemarks. Please help me to get the
solution

Eg.

KML
