count value in a string between the parenthese

Hi,

I've got a string that contains "(Value)" and i'd like to count them.

What functions whould i use?

Count occurrences or add values? Single string with multiple occurrences or multiple strings?

Count the caracters between the Parenthese in a single string

(vl-string-position (ascii "(") "aa(bbb)cccc")

Or:

(vl-string-search "(" "aa(bbb)cccc")

(defun parPosition (string / PositionStart PositionEnd)
   (setq PositionStart (vl-string-position (ascii "(") string))
   (setq PositionEnd (vl-string-position (ascii ")") string))
   (setq Count (- PositionEnd PositionStart))
   Count
)

Like this

How do I control an error of if block not selected return to the beginning?

(defun parPosition (string / PositionStart PositionEnd)
   (setq PositionStart (vl-string-position (ascii "(") string))
   (setq PositionEnd (vl-string-position (ascii ")") string))
   (setq Count (- PositionEnd PositionStart))
   Count
)

You should start a new topic. And explain better.

I did but in my other routine

Try this once

(vl-list->string (reverse (member 41 (reverse (member 40 (vl-string->list "aa(bbb)cccc"))))))
