c# asp.net 如何取下面的kml文件
如何用vs2008 c# asp.net 读下面的kml文件
只要<Placemark>的name 和longitude latitude.
<name>1</name>
<LookAt>
<longitude>128.8574432157351</longitude>
<latitude>35.80600083716327</latitude>
(如果是xml, 会遇到gx:altitudeMode 这个地方总是提示错误)
以下是kml 文件如下
<?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" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">

[解决办法]
注意有命名空间，参考：http://blog.csdn.net/fangxinggood/article/details/5978613
[解决办法]
xpath没写好
[解决办法]
按你的说法，通过coordinates的条件找name的方法
/x:Document/x:Folder/x:Placemark[x:Point/x:coordinates='114.4744460035643,30.59598487608687,0']/x:name
