Google maps api 3 GeoXml3从ASP文件解析KML或XML时出错

我正在加载带有geoxml3的地图。如果我使用kml文件或xml字符串，它可以正常工作

KML版本（正常）

XML字符串

geoXml_1.parseKmlString("<?xml version='1.0' encoding='UTF-8'?><kml xmlns='http://earth.google.com/kml/2.0'><Placemark><name>Manfred Mustermann</name><description>Manfred Mustermann</description><Point><coordinates>7.0964850607874,51.781641735074,0</coordinates></Point><address>Musterstr 29 Aachen, 52070 Nordrhein-Westfalen</address><styleUrl>#0</styleUrl></Placemark></kml>")
if (geoXml_1.docs[0].gpolygons.length>0){ //NO ERROR IN geoXml_1.docs[0]
    [.....]
}else{
   [.....]
}

其中

map.asp

返回一个XML：

/service/map.asp

<%
Response.ContentType = "text/xml"
response.write "<?xml version='1.0' encoding='UTF-8'?><kml xmlns='http://earth.google.com/kml/2.0'><Placemark><name>Manfred Mustermann</name><description>Manfred Mustermann</description><Point><coordinates>7.0964850607874,51.781641735074,0</coordinates></Point><address>Musterstr 29 Aachen, 52070 Nordrhein-Westfalen</address><styleUrl>#0</styleUrl></Placemark></kml>"
%>

geoxml真的接受我想要做的事情吗？有可能吗？？为什么不呢

谢谢

parse

使用AJAX请求KML文档，您不能在调用parse后立即访问

文档，因为AJAX是异步运行的

使用
afterParse
-回调：

geoXml_1 = new geoXML3.parser(
  {/* options ,*/
   afterParse:function(docs){
     if (docs[0].gpolygons.length>0){ 
        //[.....]
    }else{
        //[.....]
    }
   }
  });

geoXml_1.parse('/service/map.asp');

没关系！！谢谢你是对的。现在我有其他错误，但我会尝试调整到你给我的解决方案。
<%
Response.ContentType = "text/xml"
response.write "<?xml version='1.0' encoding='UTF-8'?><kml xmlns='http://earth.google.com/kml/2.0'><Placemark><name>Manfred Mustermann</name><description>Manfred Mustermann</description><Point><coordinates>7.0964850607874,51.781641735074,0</coordinates></Point><address>Musterstr 29 Aachen, 52070 Nordrhein-Westfalen</address><styleUrl>#0</styleUrl></Placemark></kml>"
%>

geoXml_1.parse('/service/map.asp');
if (geoXml_1.docs[0].gpolygons.length>0){ //ERROR ON FIREBUG: geoXml_1.docs[0] is undefined 
    [.....]
}else{
   [.....]
}

geoXml_1 = new geoXML3.parser(
  {/* options ,*/
   afterParse:function(docs){
     if (docs[0].gpolygons.length>0){ 
        //[.....]
    }else{
        //[.....]
    }
   }
  });

geoXml_1.parse('/service/map.asp');
