ABAP中正则表达式的简单使用方法 (转老白BLOG)详解编程语言

在一个论坛上面看到有人在问正则表达式的问题，特举例简单说明一下。
另外，REPLACE也支持REGEX关键字。
最后：只能是ECC6或者更高版本才可以(ABAP supports POSIX regular expressions as of Release 7.00)

REPORT z_barry_test.

DATA: str TYPE string ,
result_tab TYPE match_result_tab ,
wa LIKE LINE OF result_tab.

*找出STRING里面的双字节字符
str = ‘abc我啊adfsf们’.
FIND ALL OCCURRENCES OF REGEX ‘[^x00-xff]*’ IN str RESULTS result_tab.
LOOP AT result_tab INTO wa.
WRITE / str+wa-offset(wa-length).
ENDLOOP.

*找出STRING里面的单字节字符
str = ‘abc我啊adfsf们’.
FIND ALL OCCURRENCES OF REGEX ‘[x00-xff]*’ IN str RESULTS result_tab.
WRITE / ‘—–‘.
LOOP AT result_tab INTO wa.
WRITE / str+wa-offset(wa-length).
ENDLOOP.

*找出STRING里面的IP地址
str = ‘IP1:172.16.32.12 IP2:192.168.1.1 ‘.
FIND ALL OCCURRENCES OF REGEX ‘d+.d+.d+.d+’ IN str RESULTS result_tab.
WRITE / ‘—–‘.
LOOP AT result_tab INTO wa.
WRITE / str+wa-offset(wa-length).
ENDLOOP.

*找出STRING里面的***-********格式的电话号码

FIND ALL OCCURRENCES OF REGEX ‘d{3}-d{8}|d{4}-d{7}’ IN str RESULTS result_tab.
WRITE / ‘—–‘.
LOOP AT result_tab INTO wa.

ENDLOOP.

*找出STRING里面的15/18位身份证号码
str = ‘IP1:172.16.32.12 3722198003041234 ‘.
FIND ALL OCCURRENCES OF REGEX ‘d{15}|d{18}’ IN str RESULTS result_tab.
WRITE / ‘—–‘.
LOOP AT result_tab INTO wa.
WRITE / str+wa-offset(wa-length).
ENDLOOP.
