Element [ ] could not be unmarshalled as is not known in this context

[NickMackz]

I'm trying to unmarshal this WMS_Capabilities XML, but I'm getting this error:
Element [{http://mapserver.gis.umn.edu/mapserver}ms:GetStyles] could not be unmarshalled as is not known in this context and the property does not allow DOM content.

I've tried to add a mapping with the anyElement property to deal with it but I can't figure out how to get it to work. Is there a way to completely ignore elements that aren't known in the context?

Here is my code for my module and the context I'm using:

import {Jsonix as jsonix} from 'jsonix';
import {XLink_1_0 as xLink} from 'w3c-schemas';
import * as ogcSchemas from 'ogc-schemas';

const ANY_MODULE = {
  name: 'anyModule',
  typeInfos: [{
    type: 'classInfo',
    localName: 'AnyElementType',
    propertyInfos: [{
      type: 'anyElement',
      name: 'any',
      collection: true,
      allowDom: true,
    }],
  }],
  elementInfos: [{
    elementName: 'WMS_Capabilities',
    typeInfo: 'anyModule.AnyElementType',
  }],
};

export const WMS_CONTEXT = new jsonix.Context([
  ANY_MODULE,
  xLink,
  ogcSchemas.SMIL_2_0,
  ogcSchemas.SMIL_2_0_Language,
  ogcSchemas.GML_2_1_2,
  ogcSchemas.GML_3_1_1,
  ogcSchemas.Filter_1_0_0,
  ogcSchemas.Filter_1_1_0,
  ogcSchemas.SE_1_1_0,
  ogcSchemas.OWS_1_0_0,
  ogcSchemas.OWS_1_1_0,
  ogcSchemas.WMS_1_0_0,
  ogcSchemas.WMS_1_1_0,
  ogcSchemas.WMS_1_1_1,
  ogcSchemas.WMS_1_3_0,
  ogcSchemas.WMS_1_3_0_Exceptions,
  ogcSchemas.SLD_1_0_0,
  ogcSchemas.SLD_1_0_0_GeoServer,
  ogcSchemas.SLD_1_1_0,
]);

WMS 1.3.0 allows for extensions via wms:_ExtendedOperation. So basically you need a mapping which would define ms:GetStyles as a substitution for wms:_ExtendedOperation.

Actually the easiest would be simply compiling this schema:
http://ogc.bgs.ac.uk/cgi-bin/exemplars/BGS_Bedrock_and_Superficial_Geology/ows?language=eng&service=WMS&version=1.3.0&request=GetSchemaExtension

Otherwise check SLD_1_1_0.js for how GetLegendGraphic is defined.

Thanks for the quick response.

I've tried compiling that schema with
java -jar node_modules/jsonix/lib/jsonix-schema-compiler-full.jar -d jsonix/mappings -p GetStyles jsonix/schema/getstyles.xsd

But I get a few errors and it fails:

[ERROR] Property "Title" is already defined. Use <jaxb:property> to resolve this conflict.

[ERROR] org.hisrc.jsonix.execution.JsonixInvoker - The model is null, there was probably a problem parsing schemas.

Yes, OGC schemas are a bit hard to compile. It will be probably easier if you just write mappings manually. Probably something like:

var MS_1_0_0_Module_Factory = function () {
  var MS_1_0_0 = {
    n: 'MS_1_0_0',
    dens: 'http://mapserver.gis.umn.edu/mapserver',
    deps: ['OWS_1_0_0', 'SE_1_1_0', 'Filter_1_1_0', 'GML_3_1_1', 'WMS_1_3_0'],
    tis: [],
    eis: [{
        en: 'GetStyles',
        ti: 'WMS_1_3_0.OperationType',
        sh: {
          lp: '_ExtendedOperation',
          ns: 'http:\/\/www.opengis.net\/wms'
        }
      }]
  };
  return {
    MS_1_0_0: MS_1_0_0
  };
};
if (typeof define === 'function' && define.amd) {
  define([], MS_1_0_0_Module_Factory);
}
else {
  var MS_1_0_0_Module = MS_1_0_0_Module_Factory();
  if (typeof module !== 'undefined' && module.exports) {
    module.exports.MS_1_0_0 = MS_1_0_0_Module.MS_1_0_0;
  }
  else {
    var MS_1_0_0 = MS_1_0_0_Module.MS_1_0_0;
  }
}

No guarantees, but you get the idea.

Thanks. I've got it working now by writing the mappings manually and compiling inspire_common.

In case they are useful to anyone else:

const MAP_SERVER_1_0_0 = {
  name: 'mapServer',
  dens: 'http://mapserver.gis.umn.edu/mapserver',
  deps: ['WMS_1_3_0'],
  eis: [{
    en: 'Service',
  }, {
    en: 'GetStyles',
    ti: 'WMS_1_3_0.OperationType',
    sh: {
      lp: '_ExtendedOperation',
      ns: 'http://www.opengis.net/wms',
    },
  }],
};

const INSPIRE_VS_1_0_1 = {
  name: 'inspire_vs',
  dens: 'http://inspire.ec.europa.eu/schemas/inspire_vs/1.0',
  deps: ['WMS_1_3_0', 'INSPIRE_COMMON_1_0_1'],
  eis: [{
    en: 'ExtendedCapabilities',
    ti: 'INSPIRE_COMMON_1_0_1.ExtendedCapabilitiesType',
    sh: {
      lp: '_ExtendedOperation',
      ns: 'http://www.opengis.net/wms',
    },
  }],
};
