Extract <name> attribute from KML
- by Ozaki
I am using OpenLayers for a mapping service.
In which I have several KML layers that are using KML feeds from server to populate data on the map.
It currently plots: images / points / vector lines & shapes.
But on these points it will not add a label with the value of the for the placemark in the KML.
What I have currently tried is:
////////////////////KML Feed for * Layer//
var surveylinelayer = new OpenLayers.Layer.Vector("First KML Layer", {
projection: new OpenLayers.Projection("EPSG:4326"),
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: firstKMLURL,
format: new OpenLayers.Format.KML({
extractStyles: true,
extractAttributes: true
})
}),
styleMap: new OpenLayers.StyleMap({
"default": KMLStyle
})
});
then the Style as follows:
var KMLStyle = new OpenLayers.Style({
//label: "${name}", // This method will display nothing
fillOpacity: 1,
pointRadius: 10,
fontColor: "#7E3C1C",
fontSize: "13px",
fontFamily: "Courier New, monospace",
fontWeight: "strong",
labelXOffset: "0",
labelYOffset: "-15"
}, {
//dynamic label
context: {
label: function(feature) {
return "Feature Name: " + feature.attributes.name; // also displays nothing
}
}
});
Example of the KML:
<Placemark>
<name>POI1</name>
<Style>
<LabelStyle>
<color>ffffffff</color>
</LabelStyle>
</Style>
<Point>
<coordinates>0.000,0.000</coordinates>
</Point>
</Placemark>
When debugging I just hit "feature is undefined" and am unsure why it would be undefined in this instance?
