WFS GetFeature output from ArcGIS cannot be parsed with any ol.format.*

Question

A simple ol.format.ogc.filter.bbox works with no problem using Geoserver, and I can parse the output xml as follows:

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

However; when using the same filter with ArcGIS the output xml cannot be parsed. The results returned by the map server are correct, but the code above parses only the first feature returned. I tried using new ol.format.GML2 which parses the right amount of features but with no geometry, so I think it is not the case. There is a clear difference in the output xmls (see below).

How can I parse the second xml (returned by ArcGIS) using OpenLayers 3? Is there a way to change the output xml in ArcGIS?

Answer 1

Use ol.format.WFS that should work.
