cascade special characters

[Former Member]

Hi,

I am trying to

parse a string and escape (\) everything that's not a letter.

How can it be done ?

e.g.

User enters w+

His input ( through select-options )

w+ must be escaped as w\+

data lv_string(20) type c.
 
select-options s_input for lv_string.
 
 
DATA: moff TYPE i,
      mlen TYPE i,
      s type string.
 
translate s_input-low TO LOWER CASE.
 
 
FIND REGEX s_input-low IN 'xcdfedfrfv'
     MATCH OFFSET moff
     MATCH LENGTH mlen.

Hi,

try this:

REPORT test.

CONSTANTS:

maxstrlen TYPE i VALUE 10.

PARAMETER x(maxstrlen) LOWER CASE.

DATA:

off TYPE i,

off_y TYPE i,

len TYPE i,

y LIKE x.

len = STRLEN( x ).

WHILE ( off < len ) AND ( off_y < maxstrlen ).

IF NOT ( ( xoff(1) >= 'a' AND xoff(1) <= 'z' ) OR

( xoff(1) >= 'A' AND xoff(1) <= 'Z' ) ).

y+off_y(1) = '\'.

off_y = off_y + 1.

ENDIF.

IF off_y < maxstrlen.

yoff_y(1) = xoff(1).

ENDIF.

off = off + 1.

off_y = off_y + 1.

ENDWHILE.

x = y.

WRITE x.

hi check this..

data lv_string(20) type c.

select-options s_input for lv_string.

DATA: moff TYPE i,

mlen TYPE i,

s type string.

translate s_input-low TO LOWER CASE.

replace all occurrences of 'w' in s_input-low with 'w/' .

regards,

or have a look at CL_ABAP_REGEX and the parameter SIMPLE_REGEX:

DATA: regex TYPE REF TO cl_abap_regex,
      moff TYPE i,
      mlen TYPE i,
      text  TYPE        string.

text = 'xcdfedf+rfv'.

CREATE OBJECT regex
  EXPORTING
    pattern      = 'f+'
    simple_regex = 'X'.

FIND REGEX regex IN text
     MATCH OFFSET moff
     MATCH LENGTH mlen.

write: moff, mlen.
