如何解析文件geoxml3中的字符串？

Question

我想解析这个文件：http://www.emsc-csem.org/Earthquake/Map/earth/kml.php和geoxml3。

我通过代理下载此文件，但我不知道如何解析字符串

例如，我想解析一个字符串：

<name> ..... </name> 
<description>....</description>

你能帮助我吗？

Answer 1

要使用[geoxml3](https://github.com/geocodezip/geoxml3)解析字符串（包含KML），请使用解析器的.parseKmlString方法。

map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
geoXml = new geoXML3.parser({
  map: map,
  singleInfoWindow: true
});
geoXml.parseKmlString(kmlData); // kmlData contains a string containing valid KML

proof of concept fiddle

代码段：

var geoxml = null;

function initialize() {
  var myLatlng = new google.maps.LatLng(39.397, -100.644);
  var myOptions = {
    zoom: 5,
    center: myLatlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
  geoXml = new geoXML3.parser({
    map: map,
    singleInfoWindow: true
  });
  geoXml.parseKmlString(kmlData);
}
google.maps.event.addDomListener(window, "load", initialize);
var kmlData = '<?xml version="1.0" encoding="UTF-8"?><kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2"><Document><name>EMSC - Last 2 Weeks earthquakes
