Loop multiple .kml files from directory

I have a set of .kml files with information that I want to load one by one stack in a 3D array. I made the first step manually like this:

a = extractfield(kml2struct('Bus1.kml'),'Latitude');

b = extractfield(kml2struct('Bus1.kml'),'Longitude');

c(:,1,1) = a; c(:,2,1) = b;

So, c should be the 3D array and the next loop should perform:

a = extractfield(kml2struct('Bus2.kml'),'Latitude');

b = extractfield(kml2struct('Bus2.kml'),'Longitude');

c(:,1,2) = a; c(:,2,2) = b;

Etc...

How can I do this?
