Coordinates from KmlDataSource

CesiumJS
1

Hello!

How do i get coordinates from KML or KMZ file? I have this javascript funtion that loads kml file and zooms to specified coordinates.

function LoadKMZKML(file){
  viewer.dataSources.add(Cesium.KmlDataSource.load(file));
  var coordinates=?;
        viewer.camera.flyTo({
  destination : Cesium.Cartesian3.fromDegrees(coordinates)
       
});
    
}

Assuming you just want to fly to the KML file extent, you can use viewer.flyTo instead of viewer.camera.flyTo

var promise = viewer.dataSources.add(Cesium.KmlDataSource.load(file));

viewer.flyTo(promise);

Thank you

Viewer.flyTo works but i still need position of the model for this other function rajaa().

function LoadKMZKML(file){
        var p=viewer.dataSources.add(Cesium.KmlDataSource.load(file));
  viewer.flyTo(p);
  rajaa(longitude,latitude);
  }

function rajaa(longitude,latitude) {
        scene.screenSpaceCameraController.maximumZoomDistance=5000.0;
        center = Cesium.Cartesian3.fromDegrees(longitude,latitude,0.0);
        transform = Cesium.Transforms.eastNorthUpToFixedFrame(center);
        camera = viewer.camera;
        camera.constrainedAxis = Cesium.Cartesian3.UNIT_Z;
        camera.lookAtTransform(transform);
        }

I think you must iterate all your entities to get the right position. but you can identify an entity by setting an ID within your kml and starting iterate from it.
or if you find other solution I will also take it.
