You can only retrieve/append markers from/to a markers layer:
http://dev.openlayers.org/apidocs/files/OpenLayers/Layer/Markers-js.html
To retrieve an array of the markers layers in your map use
Map.getLayersByClass("OpenLayers.Layer.Markers"). Make sure that you
previously attached a markers layer to your map.
