Actually, what I want to achieve is basically replace loading the xml
data through the database with the php script with another method that
would load the polygons from the kml file. Today, the
marcadoresBairros.js does the following (see the comments):
var bairro_parametro = nome;
var parametro = "carregaBairros.php?nome=";
// this will make the php script load the polygon for a specific
neighborhood
// instead of using the php script to get the data from the database
we want
// to be able to parse a kml file with the same information
GDownloadUrl(parametro + bairro_parametro, function(data) {
var xml = GXml.parse(data);
var markers = xml.documentElement.getElementsByTagName
("marker");
for (var i = 0; i < markers.length; i++) {
var bairro = eval(markers[i].getAttribute("bairro"));
if (overlay!=null){map.removeOverlay(overlay);}
overlay = new GPolygon(bairro, "#ff3c00", 2, 0.7,
"#ffdcd1", 0.5 );
var centro = overlay.getBounds().getCenter();
map.panTo(centro);
map.addOverlay(overlay);
}
Thanks!
