[OpenLayers-Users] KML icons [workaround / monkeypatch included]

[Egil Möller]

It seems to be a pure bug. Here is workaround code:

      MapServer.Format.KML = OpenLayers.Class(OpenLayers.Format.KML, {
        CLASS_NAME: "MapServer.Format.KML",
        parseStyle: function(node) {
          var baseURI = node.baseURI.split("?")[0]; // remove query, if any
          if (baseURI.lastIndexOf("/") != baseURI.length - 1) {
            baseURI = baseURI.substr(0, baseURI.lastIndexOf("/") + 1);
          }
          var style = 
OpenLayers.Format.KML.prototype.parseStyle.call(this, node);
          if (typeof style.externalGraphic != "undefined" &&
style.externalGraphic.match(new RegExp("(^/)|(://)")) == null) {
            style.externalGraphic = baseURI + style.externalGraphic;
          }
          return style;
        }
      });

Best reards,
Egil
