[OpenLayers-Users] Can not Extract KML Attribute

[Arnd Wippermann]

It seems, that the propertyStyles for label have to be set.
 
something like this:
pois["styleMap"]["styles"]["default"]["propertyStyles"] = {"label":true};
 
Example:
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL212/kml_csv_data_layer/kml_csv_
data_layer.asp?propertyStyles=true

Betreff: [OpenLayers-Users] Can not Extract KML Attribute


OL Users,

Could some one please help?

I can not extract attributes in a KML file. Here is my KML:

<?xml version="1.0" encoding="utf-8" ?>
<kml xmlns="http://www.opengis.net/kml/2.2">
   <Document>
      <Folder>
         <name>ba_uf</name>
         <Schema name="ba_uf" id="ba_ufID">
            <SimpleField type="string" name="ID"></SimpleField>
            <SimpleField type="string" name="Regiao"></SimpleField>
            <SimpleField type="string" name="State"></SimpleField>
            <SimpleField type="float" name="Area"></SimpleField>
         </Schema>
         <Placemark>
            <Style>
               <LineStyle><color>ff0000ff</color></LineStyle>
               <PolyStyle><fill>0</fill></PolyStyle>
            </Style>
            <ExtendedData>
               <SchemaData schemaUrl="#ba_ufID">
                  <SimpleData name="ID">2909901</SimpleData>
                  <SimpleData name="Regiao">Nordeste></SimpleData>
                  <SimpleData name="State">BAHIA></SimpleData>
                  <SimpleData name="Area">0</SimpleData>
               </SchemaData>
            </ExtendedData>
        <Polygon>
            <tessellate>1</tessellate>
            <outerBoundaryIs>
                <LinearRing>
                    <coordinates>
                        -39.76265494838268,-12.27246488227016,0

</kml>

This what I am using to extract and style the attributes:

...
        new OpenLayers.Layer.Vector("ESTADO DA BAHIA", {
            strategies: [new OpenLayers.Strategy.Fixed()],
            protocol: new OpenLayers.Protocol.HTTP({
                url: "kml/ba_uf_900913a.kml",
                format: new OpenLayers.Format.KML({
                   extractStyles: false, 
                   extractAttributes: true,
                   srsName: "EPSG:900913"
                })
            }),
                style: {
                  fillColor: "#ffffff",
                  fillOpacity: 0,
                  strokeWidth: 1, 
                  strokeColor: "#0000ff", 
                  strokeOpacity: 1,
                  label: "${State}",
                  fontColor: "#ffffff",
                  fontFamily: "sans-serif",
                  fontSize: "15px",
                  fontWeight: "bold"
                }
...

I want the attribute for State to be rendered on the map, but I only get
${State} rendered.

I've tried additng <value></value> and label: "${State}" or label:
"${State.value}" . I get either ${State} or ${State.value} rendered on the
map, but never the actual attribute, which is BAHIA.

I just can´t get it to work. Could someone help please?

Thanks a lot in advance.

Reinaldo
