ssget: add a filter for xdata

Hello! A tittle question...

Is it possible to make a ssget with XDATA values?

(ssget "_A" '((0 . "TEXT") (8 . "CB_Richiami") (-3 ("_XDATA" (1000 . "196") (1000 . "196"))) 
))

That code returns always nil (

Maybe the only solution is the selection set processing..

Thanks for your help!

Dennis

Unfortunately you can only filter to the level of the application name (see here); you will therefore need to perform the additional filtering by testing each entity when processing the selection set.

Thanks for the reply Mr. Lee!

Yeah, as i thought I need to process that list..

(defun mod_elementi (/)
 (IF (setq s (ssget "_A" '((0 . "TEXT") (8 . "CB_Richiami"))))
 (progn
           (setq i 0
                 n (sslength s)
                 )
                 
   (while (< i n)
             (progn
               (IF (/= (substr (cdr (assoc 1 (entget (ssname s i)))) 1 2) "1%")
               (progn
                 (setq x (car s))
                 (vl-remove x (cdr s))
                 (setq n (1- n))
                 
                        )
               )
               (setq i (1+ i))
     )
 )
 )
 )
 )

(setq x (car s)) this requires a list.. I need to convert the selection set to a list before.. anyway it's the right way?

Thanks!

What are you trying to modify Dennis?

This is a little part of a more complex bug fix of a program I use.

I've done the fix in another way but it's very inefficient so I started to rewrite the lisp.

This is the old code:

(DEFUN c:test (/)
 (IF (SETQ s (SSGET '((0 . "TEXT") (8 . "CB_Richiami"))))
   (PROGN (SETQ i 0
                n (SSLENGTH s)
          )
          (WHILE (< i n)
            (IF (= (SUBSTR (CDR (ASSOC 1 (ENTGET (SSNAME s i)))) 1 2) "1%")
              (PROGN (SETQ e               (SSNAME s i)
                           testo_originale (SUBSTR (CDR (ASSOC 1 (ENTGET (SSNAME s i))))
                                                   2
                                                   20
                                           )
                           x_data          (CDR (CADR (CAR (CDR (ASSOC -3 (ENTGET e '("*")))))))
                     )
                     (conta_barre x_data)
;;;                      (SETQ vobject (VLAX-ENAME->VLA-OBJECT e))
;;;                      (SETQ text (VLA-GET-TEXTSTRING vobject))
;;;                      (VLA-PUT-TEXTSTRING vobject "New text string")
                        (setq testo_modificato (strcat (itoa n_ferri) testo_originale ))
                        (entmod (SUBST (CONS 1 testo_modificato) (ASSOC 1 (entget e)) (entget e)))
              )
            )
            (SETQ i (1+ i))
          )
   )
 )
)

(defun conta_barre (x / i n freccie x_data x e)
 (if (setq freccie (ssget "_A" '((0 . "INSERT") (8 . "CB_Richiami"))))
 (progn
           (setq i 0
                 n_ferri -1
                 n (sslength freccie)
           )
 
           (while (< i n)
               (setq e (ssname freccie i)
                     x_data (cdr (cadr (car (cdr (assoc -3 (entget e '("*")))))))
                     i (1+ i)
               )
             
               (IF (= x_data x)
                 (setq n_ferri (1+ n_ferri))
                 )

           )
       )
 )
 )

It's related to another post you've answered...

http://www.cadtutor.net/forum/showthread.php?97959-Find-where-are-stored-information-about-an-entity/page4

Instead of create the quote (wasn't able to identify the number of the bar) I want only to correct in a brutal way the number in front of the text.

I've discovered that ARROWS have the same XDATA of the text I want to modify.

The idea for the new code is to:

1. get a selection set of all these arrows

2. using your code (THANKS!) to create a list with (XDATA . N°_ITEMS)

3. search TEXT with 1st, 2nd, etc, element of xdata from your code

4. entmod it with the correct number

This is what I've write until now:

(defun C:test (/)
 (if (setq s (ssget '((0 . "INSERT") (8 . "CB_Richiami") (2 . "aca_freccia"))))
 (progn
           (setq i 0
                 n (sslength s)
                 lista nil
           )
           (while (< i n)
             (progn
               (setq e (ssname s i)
                     
                     x (cdr (cadr (car (cdr (assoc -3 (entget e '("*")))))))
                     i (1+ i)
               )

             (setq lista (append (list x) lista))
              
              
              

;;;                (setq testo_modificato (strcat (itoa n_ferri) testo_originale ))
;;;        (entmod (SUBST (CONS 1 testo_modificato) (ASSOC 1 (entget e)) (entget e)))

           )
             );end while
(setq lst (LM:CountItems lista))
   
       )
   )
(mod_elementi)
 
 )

(defun LM:CountItems ( l / c x )
   (if (setq x (car l))
       (progn
           (setq c (length l)
                 l (vl-remove x (cdr l))
           )
           (cons (cons x (- c (length l))) (LM:CountItems l))
       )
   )
)

(defun mod_elementi (/)
 (IF (setq s (ssget "_A" '((0 . "TEXT") (8 . "CB_Richiami"))))
 (progn
           (setq i 0
                 n (sslength s)
                 )
                 
   (while (< i n)
             (progn
               (IF (/= (substr (cdr (assoc 1 (entget (ssname s i)))) 1 2) "1%")
               (progn
                 (setq x (car s))
                 (vl-remove x (cdr s))
                 (setq n (1- n))
                 
                        )
               )
               (setq i (1+ i))
     )
 )
 )
 )
 )

I'm stacked with the point 3..

Anyway the point 4 (entmod) create some problems.. a lot of items generated with the program I use get messed. I don't know why..

If I ssget little portions of drawing that doesn't happen. FIXED
