GIS的学习（十九）Geoserver使用添加，删除，查询地图中的POI

   在geoserver自定义的地图中通过geoserver wfs 查询，删除，添加相关的POI。

相关操作的格式如下：

查询

<wfs:GetFeature service="WFS" version="1.0.0"  
       outputFormat="GML2"  
       xmlns:opengis="http://www.cetusOpengis.com"  
       xmlns:wfs="http://www.opengis.net/wfs"  
       xmlns:ogc="http://www.opengis.net/ogc"  
       xmlns:gml="http://www.opengis.net/gml"

       xsi:schemaLocation="http://www.opengis.net/wfs   http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd">   
       <wfs:Query typeName="opengis:qqy">   
      <ogc:Filter>   
      <ogc:PropertyIsEqualTo>
      <ogc:PropertyName>status</ogc:PropertyName>
      <ogc:Literal>0</ogc:Literal>
      </ogc:PropertyIsEqualTo>
     </ogc:Filter>   
       </wfs:Query>   
    </wfs:GetFeature>;

 

添加

<wfs:Transaction service="WFS" version="1.0.0"  
       outputFormat="GML2"  
       xmlns:opengis="http://www.cetusOpengis.com"  
       xmlns:wfs="http://www.opengis.net/wfs"

             <opengis:status>0</opengis:status>
          </opengis:someprj>
       </wfs:Insert>  
    </wfs:Transaction>;

修改

<wfs:Transaction service="WFS" version="1.0.0"  
       outputFormat="GML2"  
       xmlns:opengis="http://www.cetusOpengis.com"  
       xmlns:wfs="http://www.opengis.net/wfs"
