[OpenLayers-Users] Multipolygon to Polygons

[Slawomir Messner]

Let's assue you have only the one MultiPolygon in your layer.
var mpolygon = wfs_mpolygon.features[0];
var c = null;
for (c in mpolygon.geometry.components) {
     var poly = mpolygon.geometry.components[c];
     doSomethingWith(poly);
}

Be aware that mpolygon is an instance of OpenLayers.Feature.Vector class 
and poly an instance of OpenLayers.Geometry class (in your case 
OpenLayers.Geometry.Polygon). You can find the description of the 
classes at 
http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers-js.html. 
There you can see, that an MultiPoligon inherits the OL.Geom.Collection 
class and this class has a components attribute where it stores all the 
geometries, you can learn all this by reading the api.
