读文本

Jack_PC

请问如何读取以下格式的文本文件,中间用"="号分隔,需要分别获取"="号前后的内容.
;;例如文本格式如下

红色=1
随层=256

inpos是一个自定义函数，将字符串str中的分隔符sep前后的分别读出来放到一个表中。分隔符可以为多个字符

1. (defun inpos(sep str / pos prestr sufstr russtr)
   
2.   (while (setq pos (vl-string-search sep str))
   
3.       (setq prestr (substr str 1 pos))
   
4.       (setq str (substr str (+ pos 1 (strlen sep))))
   
5.       (setq russtr (append russtr (list prestr)))
   
6.   )
   
7.   (setq russtr (append russtr (list str)))
   
8. )
   
9. 
   
10. (setq sep "=")
    
11. (setq str "红色=1")
    
12. (setq a (inpos sep str));;;a为("红色" "1")，可用(car a)调用"红色"，(cadr a)调用"1"
    
13. (setq str "随层=256")
    
14. (setq b (inpos sep str));;;b为("随层" "256")，可用(car b)调用"随层"，(cadr b)调用"256"
    
15. (setq sep "通道")
    
16. (setq str "明经通道论坛")
    
17. (setq c (inpos sep str));;;c为("明经" "论坛")，可用(car c)调用"明经"，(cadr c)调用"论坛"
    
18. (setq sep "-")
    
19. (setq str "1-2-3-4-5")
    
20. (setq d (inpos sep str));;;d为("1" "2" "3" "4" "5")
    
21. (setq sep "**")
    
22. (setq str "明**经**通**道**论**坛")
    
23. (setq e (inpos sep str));;;e为("明" "经" "通" "道" "论" "坛")

(defun inpos(sep str / pos prestr sufstr russtr)<br />   (while (setq pos (vl-string-search sep str))<br />       (setq prestr (substr str 1 pos))<br />       (setq str (substr str (+ pos 1 (strlen sep))))<br />       (setq russtr (append russtr (list prestr)))<br />   )<br />   (setq russtr (append russtr (list str)))<br /> )<br /> <br /> (setq sep "=")<br /> (setq str "红色=1")<br /> (setq a (inpos sep str));;;a为("红色" "1")，可用(car a)调用"红色"，(cadr a)调用"1"<br /> (setq str "随层=256")<br /> (setq b (inpos sep str));;;b为("随层" "256")，可用(car b)调用"随层"，(cadr b)调用"256"<br /> (setq sep "通道")<br /> (setq str "明经通道论坛")<br /> (setq c (inpos sep str));;;c为("明经" "论坛")，可用(car c)调用"明经"，(cadr c)调用"论坛"<br /> (setq sep "-")<br /> (setq str "1-2-3-4-5")<br /> (setq d (inpos sep str));;;d为("1" "2" "3" "4" "5")<br /> (setq sep "**")<br /> (setq str "明**经**通**道**论**坛")<br /> (setq e (inpos sep str));;;e为("明" "经" "通" "道" "论" "坛")

个人认为cabinsummer 的思路更清晰，代码更简洁

非常感谢各位的指导，我再去试试
