It's all in how you filter your selection set.
(ssget "x" '((0 . "POLYLINE,LWPOLYLINE")(8 . "MYLAYER,YOURLAYER")))
for example, will find all Polylines and LWPolylines on layers MYLAYER and
YOURLAYER).
Or, you could prompt the user for the layer name(s) and use the construct
(setq LayName (getstring "\nLayer Name: ")
ss (ssget "x" (list '(0 . "POLYLINE,LWPOLYLINE")(cons 8 LayName)))
)
