[Qgis-user] QGIS Server: Parsing WFS capabilites with JavaScript

[Jorge Gustavo Rocha]

Hi Jakob,

You can try jsonix. I use something like:

var Jsonix = require('jsonix').Jsonix;
var XLink_1_0 = require('w3c-schemas').XLink_1_0;
var OWS_1_0_0 = require('ogc-schemas').OWS_1_0_0;
var OWS_1_1_0 = require('ogc-schemas').OWS_1_1_0;
var WFS_1_0_0 = require('ogc-schemas').WFS_1_0_0;
var WFS_1_1_0 = require('ogc-schemas').WFS_1_1_0;
var WFS_2_0 = require('ogc-schemas').WFS_2_0;
var Filter_1_0_0 = require('ogc-schemas').Filter_1_0_0;
var Filter_1_1_0 = require('ogc-schemas').Filter_1_1_0;
var Filter_2_0 = require('ogc-schemas').Filter_2_0;
var GML_1_0_0 = require('ogc-schemas').GML_1_0_0;
var GML_2_1_2 = require('ogc-schemas').GML_2_1_2;
var GML_3_1_1 = require('ogc-schemas').GML_3_1_1;
var GML_3_2_0 = require('ogc-schemas').GML_3_2_0;
var GML_3_2_1 = require('ogc-schemas').GML_3_2_1;
var SMIL_2_0 = require('ogc-schemas').SMIL_2_0;
var SMIL_2_0_Language = require('ogc-schemas').SMIL_2_0_Language;
var CSW_2_0_2 = require('ogc-schemas').CSW_2_0_2;
var DC_1_1 = require('ogc-schemas').DC_1_1;
var DCT = require('ogc-schemas').DCT;
var XMLSchema = require('./mappings/XMLSchema').XMLSchema;

var context = new Jsonix.Context([
   XLink_1_0,
   OWS_1_0_0,
   OWS_1_1_0,
   WFS_1_0_0,
   WFS_1_1_0,
   WFS_2_0,
   Filter_1_0_0,
   Filter_1_1_0,
   Filter_2_0,
   GML_1_0_0,
   GML_2_1_2,
   GML_3_1_1,
   GML_3_2_0,
   GML_3_2_1,
   SMIL_2_0,
   SMIL_2_0_Language,
   CSW_2_0_2,
   DC_1_1,
   DCT,
   XMLSchema
]);
var unmarshaller = context.createUnmarshaller();

Later, you can transform WFS response to JSON, like:

     const response = responseBuffer.toString('utf8');
     var result = unmarshaller.unmarshalString(response);

Not so easy, but it works.

Regards,

Jorge Gustavo
