;;;Thanks to J. Roper for this section:

;ATT:GETS - Utility routine to get all attributes for
;an insert object (EN).
;;
;;You pass this function an entity name, like something that would be returned from this example:
;;(setq EN (car (entsel "\nSelect block")))
;;an entity name looks like this when returned on a command line --><Entity name: 4119ab90>
;;You use this function like this: (setq ATTLIST (ATT:GETS EN))
;;it returns a list like this ---> (("TAG1 . "VALUE1")("TAG2" . "VALUE2")....)
(defun ATT:GETS
(EN
/ EL RES
) ;entnext goes on to the next entity. If what you passed is an attributed block, the next entity will be an attribute.
EL
(entget EN
));entget "breaks open" the entity name to reveal the entity list (while (= "ATTRIB" (cdr (assoc 0 EL
)));we check the entity list to see if it is an attribute (cons (cdr (assoc 2 EL
));if it is, we create a list of its tag and value, dxf code 2 and 1, using CONS EN
(entnext EN
);go to the next entity EL
(entget EN
)));get the next entities list (reverse RES
);reverse the list to put it in proper order. )
