Replace multiple text

Hello

Here's my problem. I ve got hundreds of texts contain letters and numbers like this 'TT01 23+566.66' 'TT02 22+364.64' 'TT03 28+556.89'. So i need the first part of the text which is TT'number' to be removed. I cant do that with the basic find and replace tool because numbers are different. Is there any lisp you know to handle this?

(substr str 6)

if TT'number' length varies: i.e "TT105 28+556.89" then use

(substr str (+ (vl-string-position 32 str) 2))

When in doubt, check Lee Mac out.

His BATCH FIND AND REPLACE should do the trick.

Thanks Lee!

You can also use this :

(defun STRFIND (SRC SRCH / 
               CNT
               RET
               )
  (setq CNT 1)
 (while (<= CNT (strlen SRC))
    (if
       (= (substr SRC CNT (strlen SRCH)) SRCH)
           (setq RET (list
                       (substr SRC 1 (1- CNT))
                       (substr SRC (+ CNT (strlen SRCH)))) CNT (1+ (strlen SRC))
                 )
      
           (setq CNT (1+ CNT))))
 (if (null RET) (list SRC nil) RET))



(defun c:test (/ STR)
 (setq STR (getstring "\nType in a string: "))
 (while
   (/=
     (and
       (setq SSTR (car (entsel "\nSelect a string to change: ")))
       (if
         (= (type (cdr (assoc 1 (entget SSTR)))) 'STR)
         (progn
           (setq RES (strfind (cdr (assoc 1 (entget SSTR))) STR))
           (entmod
             (subst
               (cons 1 (strcat (car RES) (cadr RES)))
               (assoc 1 (entget SSTR))
               (entget SSTR)
               )
             )
           )
         )
       )
     )
   )
 (princ)
 )

cadplayer,

You need to place your code in CODE TAGS not quote tags.

Thanks

Take it easy

As pBe correctly suggests, the substr function is the key for this task:

(defun c:txtupd ( / e i s x )
   (if (setq s (ssget "_:L" '((0 . "TEXT") (1 . "TT## *"))))
       (repeat (setq i (sslength s))
           (setq e (entget (ssname s (setq i (1- i))))
                 x (assoc 1 e)
           )
           (entmod (subst (cons 1 (substr (cdr x) 6)) x e))
       )
   )
   (princ)
)

In case it's needed, more complex regular expressions could be used with acet-str-replace, provided Express Tools are installed.
