Get values from an applied bevel and emboss effect for multiple layers?

Question

I created this function below, to get some values from an applied bevel and emboss effect, like shading angle, shading altitude etc.

alert("Angle: " + getBevelAndEmbossValues()[0] + "\nAltitude: " + getBevelAndEmbossValues()[1]);  

function getBevelAndEmbossValues()  
{    
    try  
    {    
        var ref = new ActionReference();    
        ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );     
        var desc = executeActionGet(ref).getObjectValue(stringIDToTypeID('layerEffects')).getObjectValue(stringIDToTypeID('bevelEmboss'));    
        return [desc.getUnitDoubleValue(stringIDToTypeID('localLightingAngle')),  
                desc.getUnitDoubleValue(stringIDToTypeID('localLightingAltitude'))];  
    }  
    catch(e)  
    {  
        alert(e);  
    }    
};

What I want to do now, is to do the same thing but for multiple layers. Exactly like this function below does with layer's color. I tried several things but my knowledge level didn't help. Any idea?

function getLayersData()  
{  
    var lyrs = [];  
    var layers = 1;  
    while (true)  
    {  
        ref = new ActionReference();  
        ref.putIndex(charIDToTypeID('Lyr '), layers);  

        try{var desc = executeActionGet(ref);}catch(err){alert(err);break;};  

        var lyr = {};  
        lyr.type = desc.getInteger(stringIDToTypeID("layerKind"));  
        lyr.name = desc.getString(charIDToTypeID("Nm  "));  
        lyr.id = desc.getInteger(stringIDToTypeID("layerID"));  

        if (lyr.type == layerType && lyr.name.match(layerName))  
        {  
            var adj = desc.getList(stringIDToTypeID("adjustment")).getObjectValue(0);  

            if (adj.hasKey(stringIDToTypeID("color")))   
            {  
                var curColor = new SolidColor();  
                curColor.rgb.red = adj.getObjectValue(stringIDToTypeID("color")).getUnitDoubleValue(stringIDToTypeID("red"));  
                curColor.rgb.green = adj.getObjectValue(stringIDToTypeID("color")).getUnitDoubleValue(stringIDToTypeID("grain"));  
                curColor.rgb.blue = adj.getObjectValue(stringIDToTypeID("color")).getUnitDoubleValue(stringIDToTypeID("blue"));  
                lyr.color = curColor;   

                if (lyr.color.rgb.hexValue == currentColor[0])  
                {  
                    lyrs.push(lyr);                                          
                };            
            };  
        };  
        layers++;              
    };  
    return lyrs;  
};

UPDATE:

If I use scripting listener plugin to filter out the layers who contains bevel effect and then make a for loop, like Design Phoenix wrote in comments, I just get this...

layersFiltered();
function layersFiltered() {
    var s2t = function (s) {
        return app.stringIDToTypeID(s);
    };    
    executeAction( s2t( "layersFiltered" ), undefined, DialogModes.NO );
}

Well I finally managed to solve it!! Here is my solution... If anyone has anything better...

var layers = getLayersData();
alert (layers.length + ' layers found!!!' ,  'Message');

function getLayersData()
{
    var lyrs = [];
    var layers = 1;
    while (true)
    {
        ref = new ActionReference();
        ref.putIndex(charIDToTypeID('Lyr '), layers);

        try{var desc = executeActionGet(ref);}catch (err){break;};

        var lyr = {};
        lyr.type = desc.getInteger(stringIDToTypeID("layerKind"));
        lyr.name = desc.getString(charIDToTypeID("Nm  "));
        lyr.id = desc.getInteger(stringIDToTypeID("layerID"));

        if (lyr.type == '4')
        {                            
            ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
            if(desc.hasKey(stringIDToTypeID('layerEffects')))
            {
                if(desc.getBoolean (stringIDToTypeID('layerFXVisible')))
                {
                    desc = desc.getObjectValue(stringIDToTypeID('layerEffects'));
                    if(desc.hasKey(stringIDToTypeID('bevelEmboss')))
                    {
                        desc = desc.getObjectValue(stringIDToTypeID('bevelEmboss'));
                        if(desc.hasKey(stringIDToTypeID('localLightingAngle')))
                        {
                            var BevelAndEmbossAngle = desc.getUnitDoubleValue(stringIDToTypeID('localLightingAngle'));
                            if(BevelAndEmbossAngle == '90')
                            {
                                lyrs.push(lyr);
                            }
                        }
                    }
                }
            }

        };
        layers++;            
    };
    return lyrs;
};
