Question

一个简单的 ol.format.ogc.filter.bbox 使用Geoserver没问题，我可以按如下方式解析输出xml：

features = new ol.format.GML3().readFeatures(result);

然而;在ArcGIS中使用相同的过滤器时，无法解析输出xml。地图服务器返回的结果是正确的，但上面的代码只解析返回的第一个特征。我尝试使用新的ol.format.GML2来解析正确数量的功能，但没有几何，所以我认为情况并非如此。输出xmls有明显的差异（见下文）。

如何使用OpenLayers 3解析第二个xml（由ArcGIS返回）？有没有办法在ArcGIS中更改输出xml？

利用Geoserver：

Answer 1

使用应该有效的ol.format.WFS。

无法使用任何ol.format解析ArcGIS的WFS GetFeature输出。*
