[OpenLayers-Users] parsing a GML file into different layers

[Arnd Wippermann]

Hi,
 
something like this should work:
 
var features = new OpenLayers.Format.GML().read(response);
 
if(features)
{
    if(features.constructor != Array)
        features = [features];
 
    for(var i=0;i<features.length;i++)
    {
        var ftLyr = new OpenLayers.Layer.Vector("Feature " + i);
        addLayer(ftLyr);
        ftLyr.addFeatures(features[i]);
    }
}

Arnd

Hi Eric,

thanks for your reply. I probably need to use OpenLayers. Format.GML.read()
, but how do I then split the array it returns into different layers?

Thanks,

Alex.

"OpenLayers. Filter. FeatureId" could do something like this, but the
documentation on this is quite sparse..

Hi

The protocol or format that you use will give you an array of
features. You are then free to dispatch the features to separate
vector layers, for example based on their ids.

I hope it helps,
