I'm using OpenLayers to display some OSM relations and then add some tags to them. I'm using this code to add xml files to my map.

osm_layer = new OpenLayers.Layer.GML("Polygon", relation.xml, {
format: OpenLayers.Format.OSM,
style: {strokeColor: "blue"},
projection: new OpenLayers.Projection("EPSG:4326")
});

But what I need is to add more than one relation.xml per layer, as relation1.xml, relation2.xml in the SAME layer. Until know I can only show multiple xml if they go in multiple layers.

When using vectors I just created the layer and then added the vectors by something like

polygonFeature = new OpenLayers.Feature.Vector(
                 new OpenLayers.Geometry.Polygon(linearRing), style);

And then

Layer.addFeatures(polygonFeature);

However, I can't make it work with xml / OSM relation format... It should be something like

        i=1;
        while(i<relations_list.length)
        { 
            osm_layer = new OpenLayers.Layer.GML("GML") 
            map.addLayer(osm_layer);

            xml_feature = new Openlayers.Feature.Vector(relation[i], {
                    format: OpenLayers.Format.OSM,
                    style: {strokeWidth: 3},
                    projection: new OpenLayers.Projection("EPSG:4326")
                });

            osm_layer.addFeatures(xml_feature);

            i=i+1;

            if(relations_list[i]=="") {i=relations_list.length;}
        }

Thanks

Maybe a look at the source of WIWOSM can help you.
