如何一起使用
PD：抱歉我的英语。我很难解释我的需要。parse和parseKmlString？我需要表演一个 map加载一个KML文件（我使用parse(<kml_file>)）和两个XML string（我使用parseKmlString(<xml_string>)）。我如何使用useTheData在afterParse属性？我不知道如何管理这个案子。 我可以只使用一个geoxml = new geoxml.parser()三个“层”吗？ 如何在doc中管理userTheData参数以获取“KML文件” layer“或”XML string layer“？
修改过的帖子
我用ASP绘制地图。如果我得到3层，则写3对象（geoxml_1，geoxml_2和geoxml_3）。它只是一个对象，并显示和隐藏第1层或第2层....这是我的问题。真的很有用，但它不是很好的代码。当我加载de map时，它显示所有图层，并在几秒钟内，仅显示第一层并隐藏其他图层。我想只有第一层，当我点击地图内按钮中的其他图层时，它会显示并隐藏de图层。这是我的代码（抱歉，它太大了）：
function muestraCapasMapa(){
var objCapa = document.getElementById("capas_mapa");
var objFlecha = document.getElementById("flecha");
if (objCapa.className=="ocultar"){
objCapa.className = "";
objFlecha.className = "plegar";
}else{
objCapa.className = "ocultar";
objFlecha.className = "";

PD：您可以使用initialize_1()加载地图。它太重了，我希望你能更好地解释我的问题。
最终解决方案
我想我找到了解决问题的方法。最后我只创建了一个geoXml对象。我使用parse(<url>)加载了四个图层：
<url_layer>/location.asp
<url_layer>/rute.asp?tip=1
<url_layer>/rute.asp?tip=2
<url_layer>/rute.asp?tip=3"
如果您选中geoxml.docs.length，则会获得2！因此，如果我显示或隐藏layer2 o layer3可能是错误的。该解决方案已调用不同的网址获取geoxml.docs.length==4：
<url_layer>/location.asp
<url_layer>/rute1.asp
<url_layer>/rute2.asp
<url_layer>/rute3.asp

geoXml.parse(filename);
