Hi Mauro,
 
    <ExtendedData><SchemaData schemaUrl="#CALOPICOS">
        <SimpleData name="COD_PRO">16</SimpleData>
        <SimpleData name="NOME">COSTA VOLPINO</SimpleData>
        <SimpleData name="NOME_PRO">BERGAMO</SimpleData>
        <SimpleData name="SIGLA_PRO">BG</SimpleData>
        <SimpleData name="COD_ISTAT">16086</SimpleData>
    </SchemaData></ExtendedData>
 
if these your attributes, then (my guess) the Format.KML parser will not
found anything. It has to be something like <name>Something</name>.

Betreff: Re: [OpenLayers-Users] GML and KML styleMap


Yes,
I am using v. 2.7 but it's  like the extractStyles attribute  behaves
correctly.

I've come to the real problem in my code: it seems like feature attributes
are not loaded from the KML file (and extractAttributes is set to true).
(I'm debugging with firebug)
This causes visualization problem as I set a "loadend" event which modifies
the styleMap adding a rule based on one of the attributes. This works
perfectly with the GML format.

here is an excerpt of my KML file (with only 1 feature in this case):

Assuming you're using 2.7 though, this shouldn't be an issue with
extractStyles false:

 http://trac.openlayers.org/ticket/1576

So if this is the case, then we should probably look into it and fix it.

Goliah, are you using 2.7? Does this seem like it is possibly the case?
