解析GML编码的WFS响应XML文件

xml swift

解析GML编码的WFS响应XML文件,xml,swift,xml-parsing,wms,gml-geographic-markup-lan,Xml,Swift,Xml Parsing,Wms,Gml Geographic Markup Lan,我需要一些帮助，从这个GML编码的WMS响应XML文件中获取天气细节、温度等。这是我从天气服务中得到的，该服务通过Web目录服务（CSW）、Web地图服务（WMS）和Web要素服务（WFS）提供开放数据。与JSON/XML不同，我不知道这个文件中发生了什么。请为Swift 3提供一些解决方案 <?xml version="1.0" encoding="UTF-8"?> <wfs:FeatureCollection timeStamp="2017-07-31T15:48:

我无法帮助您使用swift，但我可以告诉您如何阅读此文件：

您基本上需要以下三个要素：

  <gmlcov:positions>
    61.49911 23.78712  1501516800
    61.49911 23.78712  1501520400
    61.49911 23.78712  1501524000
    61.49911 23.78712  1501527600
    61.49911 23.78712  1501531200
  </gmlcov:positions>

  <gml:doubleOrNilReasonTupleList>
        113.01 18.26 1007.03 92.74 259.0 3.79 
        113.01 17.79 1007.48 90.02 250.0 3.04 
        113.01 17.13 1007.82 93.62 229.0 2.19 
        113.01 16.42 1008.18 95.53 216.0 2.26 
        113.01 15.9 1008.89 97.09 211.0 2.74 
   </gml:doubleOrNilReasonTupleList>

 <swe:DataRecord>
    <swe:field name="GeopHeight"  xlink:href="http://"/>
    <swe:field name="Temperature"  xlink:href="http://"/>
    <swe:field name="Pressure"  xlink:href="http://"/>
    <swe:field name="Humidity"  xlink:href="http://"/>
    <swe:field name="WindDirection"  xlink:href="http://"/>
    <swe:field name="WindSpeedMS"  xlink:href="http://"/>
 </swe:DataRecord>

第二个是实际测量数据，第三个给出测量的含义。
这就是第一次测量的结果：

 GeopHeight | Temperature | Pressure | Humidity | WindDirection | WindSpeedMs
 113.01     | 18.26       | 1007.03  | 92.74    | 259.0         | 3.79

我希望这能有所帮助。

谢谢，很容易看到参数和值。问题是把它们拿出来（好的。对不起，我误解了。

 GeopHeight | Temperature | Pressure | Humidity | WindDirection | WindSpeedMs
 113.01     | 18.26       | 1007.03  | 92.74    | 259.0         | 3.79
