SosGetFois

SosGetResultJson is a specific DataSource to parse FOIs response from GetFeatureOfInterest request.

The class inherits directly from DataSource.

Parser

The parser parses the XML response from the server. The response is normalized according to the specifications of the OGC GetFeatureOfInterestResponse standard.

The parser will return an array of featureMember.

From Server:

The request looks like an XML response of this type:

<?xml version='1.0' encoding='UTF-8'?>
<sos:GetFeatureOfInterestResponse xmlns:sos="http://www.opengis.net/sos/2.0"
                                  xmlns:gml="http://www.opengis.net/gml/3.2"

After parsing:
