AutoLISP sample code for xclipped blocks

Here is a sample AutoLISP code that shows how to identify xclipped blocks.

(defun xclippedblocks (/ lst ss i ent ed xc)
  (if (setq ss (ssget "X" '((0 . "INSERT"))))
    (progn
      (setq i 0)
      (while (setq ent (ssname ss i))
       (setq ed (entget ent))
       (cond
         ((setq xc (member '(102 . "{ACAD_XDICTIONARY") ed))
          (setq xc (cdr (cadr xc)))
          (cond
            ((dictsearch xc "ACAD_FILTER")
             (setq lst (cons (cdr (assoc 2 ed)) lst))
            )
          )
         )
       )
       (setq i (1+ i))
      )
    )
  )
  lst
)
