Handle several elements at once in a collection

[PanierAvide]

To be able to use osmtogeojson library, we need OSM map data as raw XML string.

Solution : add a parameter for getting the result of fetchMapByBbox as a XML string.

Temporary workaround : using jsonToXml on client side

Or maybe it would be better to handle several elements as a sort of collection. Because I need to both know if there are elements contained in the result of the API call, and if so get them as XML string.

Also, having a collection of elements would help in the case of /[way|relation]/:id/full calls to properly handle several objects at once.

On pourrait avoir les méthodes suivantes :

• Constructeur(osmxml) : prend le résultat d'un appel API (map, element/full...)
• Constructeur(elements) : prend un tableau d'éléments JS créés par ailleurs (createNodeElement...)
• toOsmXml() : renvoie l'équivalent d'un fichier OSM XML propre, sous forme d'objet XMLDocument JS
• getElement(id) : renvoie un objet JS utilisable par les autres fonctions pour un élément précis
• setElement(id, element) : modifier un élément (suite à des appels spécifiques sur celui-ci)
• sendElements() : envoie auprès de l'API tous les éléments qui ont été modifiés

Find any node, way or relation matching the osmId in a collection generated from a raw XML converted using xmlToJson

• findElementWithinOSMCollection

Within existing functions below,

• setProperties
• setProperty
• removeProperty
• setCoordinates
• getNodeIdsForWay
• setNodeIdsForWay
• getRelationMembers
• setRelationMembers
• setTimestampToNow
• setVersion
• sendElement
• deleteElementRequest
• fetchElement Within sendElement, manage element without using osm key for root of the object and add osm root element within sendElementRequest function

const rawxml = await this._osmApi.fetchMapByBbox(bbox.getWest(), bbox.getSouth(), bbox.getEast(), bbox.getNorth());
            rawxml.osm.node = rawxml.osm.node.map(n => {
                delete n._id;
                delete n._type;
                return n;
            });
            rawxml.osm.way = rawxml.osm.way.map((w,i) => {
                delete w._id;
                delete w._type;
                return w.osm.way[0];
            });
            this._cacheOsmXml = (new window.DOMParser()).parseFromString(jsonToXml(rawxml), "text/xml");
