i try this

//-------------------------------------------------------------
var v = new OpenLayers.Layer.Vector(titulo, {
      styleMap : styleMapvlayer
});

v.events.register('featureselected', '',function(evt) {
		console.dir(typeof (evt.feature.layer.features));
		console.dir(JSON.stringify(evt.feature.layer.features));
		}
//---------------------------------------------------------------------
and my browser get crazy, and then try this


//----------------------------------------------------------------
var v = new OpenLayers.Layer.Vector(titulo, {
      styleMap : styleMapvlayer
});

v.events.register('featureselected', '',function(evt) {
		console.dir(typeof (evt.feature.layer.features[0]));
		console.dir(JSON.stringify(evt.feature.layer.features[0]));
		}

//----------------------------------------------------------------
