我加载地图与三层：隐藏/显示在谷歌地图的一些标有geoxml3

var myOptions = { 
    center: new google.maps.LatLng(36.82907321372808, -4.46044921875), 
    zoom: 4, 
    mapTypeId: google.maps.MapTypeId.ROADMAP 
}; 
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); 
var geoXml = new geoXML3.parser({ 
    map: map, 
    singleInfoWindow: false, 
    afterParse: useTheData 
}); 

geoXml.parse('data/file1.kml'); 
geoXml.parse('data/file2.kml'); 
geoXml.parse('data/file3.kml');

谁，我可以隐藏一些不标我已经隐藏所有的层？我在KML中添加了一些额外的信息来检测我必须隐藏的所有点/ poligons，但我不知道它是否是最好的工作方式。虽然它的确定，我怎么能检测的KML该标签使用例如geoXml.docs[1].markers[xx].setVisible(false);（在我的情况，我想隐藏在那里"Codigo"-tag='PRA-239'）

可以添加自定义分析功能，将<Codigo>的内容作为地标的属性，用于按钮点击处理函数。

概念证明代码片断：

var geoXml; 
 
var map; 
 

 
function initialize() { 
 
var myOptions = { 
 
    center: new google.maps.LatLng(36.82907321372808, -4.46044921875), 
 
    zoom: 4, 
 
    mapTypeId: google.maps.MapTypeId.ROADMAP 
 
}; 
 
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); 
 
    geoXml = new geoXML3.parser({ 
 
    map: map, 
 
    singleInfoWindow: false, 
 
    pmParseFn: parsePlacemark, 
 
    // afterParse: useTheData 
 
}); 
 
    geoXml.parseKmlString(file2kml); 
 

 
    google.maps.event.addDomListener(document.getElementById('toggle'), 'click', toggle); 
 

 
} 
 
// Custom placemark parse function 
 
function parsePlacemark (node, placemark) { 
 
     var tagNodes = node.getElementsByTagName('Codigo'); 
 
     var tag = null; 
 
     if (tagNodes && tagNodes.length && (tagNodes.length > 0)) { 
 
     placemark.tag = geoXML3.nodeValue(tagNodes[0]); 
 
     } 
 
} 
 

 
function toggle() { 
 
    var tag = document.getElementById('tag').value; 
 
    for (var i=0; i < geoXml.docs[0].placemarks.length; i++) { 
 
     if (geoXml.docs[0].placemarks[i].tag == tag) 
 
      if (geoXml.docs[0].placemarks[i].marker.getMap() == null) { 
 
       geoXml.docs[0].placemarks[i].marker.setMap(map); 
 
      } else { 
 
       geoXml.docs[0].placemarks[i].marker.setMap(null); 
 
      } 
 
    } 
 
} 
 

 
google.maps.event.addDomListener(window, "load", initialize);
