How to getPaths() with geoXML3

Question

I had more than 600 kml files to load in a single google map. Initially I tried with KmlLayer(), but it didn't work due to the amount of kml files, so I found GeoXML3, and it works really fine.

Now I need to retrieve the path's coords for every polygon created with GeoXML3. Here I found the method getPaths() that seems to be just what I'm looking for, but it doesn't work because now I don't create polygons using the class Polygon but using the class geoxml3

for (i=0; i < controlli.length; i++)
{   
    appo = kmlurl + controlli[i].id + ".kml";
    appo = appo.replace(" ", '_');
    area[controlli[i].id] = new geoXML3.parser({
        map: map,
        zoom: false,
    });
    area[controlli[i].id].parse(appo);
    //here I would like to do something like: 'area[controlli[i].id].getPaths()'
}

How can I do this?

geoXml3创建的用于表示KML多边形的google.maps.Polygon对象可以通过两种方式访问​​：

1. area[controlli[0].id].docs[0].placemarks[0].polygon.getPath()

1. area[controlli[0].id].docs[0].gpolygons[0].getPath()

其中geoXml是对解析器对象的引用（您的area[controlli[i].id]） 我是KML中地标（或多边形）的顺序参考。

如果您在异步加载的KML文件上使用它，则需要等待parsed事件，或使用afterParse函数中的数据。
