[OpenLayers-Dev] KML and labels from attributes

[Slawomir Messner]

  Hi,
I have a kml-layer with attributes. In the KML-file the attributes are 
stored in ExtendedData/Data tag, so OL parses an attribute into 
feat.attributes.attrib1 as object with value and displayName attributes.
Now I want that OL shows the value of one of the attributes as labels. 
To do sos I would like to use the "${attribName}" notation but with 
KML-parsed attributes it should be something like this 
"${attribName.value}" but it's not working. I think I could implement to 
follow the point to the attribute of the attribute myself, but I would 
like to know if someone has done it before, if there is another solution 
or if there is another common way to do this.
My code looks like:

this.layer.styleMap =new  OpenLayers.StyleMap({
                     "default":new  OpenLayers.Style({
                         pointRadius: 6,
                         fillColor:"#666666",
                         strokeColor:"#00FF00",
                         labelAlign:"lb",
                         label:"${"  + jQuery(this.viewSelect).val() +"}"
                     }),
                 });
It would be cool if it would work like this:
this.layer.styleMap =new  OpenLayers.StyleMap({
                     "default":new  OpenLayers.Style({
                         pointRadius: 6,
                         fillColor:"#666666",
                         strokeColor:"#00FF00",
                         labelAlign:"lb",
                         label:"${"  + jQuery(this.viewSelect).val() +".value}"
                     }),
                 });

Could someone tell me why, if I run the first code above, the labels are 
"${attribName}"? But this is not so important, if I have to implement it 
myself I will find out:)
Regards,
Slawomir
