You may not be able too.  You could loop thorough all layers and set all normal layer blend if gray to remove all white or use the magic wand set to contiguous to select the layer background and clear it.  If the background is a solid color it would be cleared.  I can not think of a way to just select White Mattes.

    In that case I have saved an action named "Remove White Matte" and saved it in a action set named "Arijit". I am trying this script below, but it is only working on the layers outside the groups....inside the groups it is not affecting any layers...

    var srcDoc = app.activeDocument;

    var numOfLayers = srcDoc.layers.length;

    for (var i = numOfLayers -1; i >= 0  ; i--)

        {    var layerName = srcDoc.layers.name;

            // check for groups

    var a = srcDoc.layers.getByName(layerName);

                app.activeDocument.activeLayer = a;

            if (srcDoc.layers.typename == "ArtLayer")

                {

                app.doAction("Remove_White_Matte", "Arijit");

                }

        }

    What does the Action Do? A script can do the same thing an action can.   You do not have to even use get by name just loop through all layers and those that are normal layers  not smart objects, text, adjustment, background, etc layers do what the Action does. Smart Object layers background could be mask off.

    #target photoshop

    app.bringToFront();

    if (!documents.length) { alert('There are no documents open.', 'No Document');}

    else {processArtLayers(activeDocument);}

    function processArtLayers(obj) {

        for( var i = obj.artLayers.length-1; 0 <= i; i--) {

             If  (obj.artLayers.kind = is the kind of layer you want to change) {

                  change the layer;

                  }

             }

        for( var i = obj.layerSets.length-1; 0 <= i; i--) {processArtLayers(obj.layerSets); } // Process Layer Set Layers

    }
