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"

<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"
