Source Code

    DATA: result TYPE i,
          substr TYPE string.
    WRITE / text.
    NEW-LINE.
    result = count( val   = text
                    regex = regx ).
    DO result TIMES.
      result = find( val   = text
                     regex = regx
                     occ   = sy-index ).
      substr = match( val   = text
                      regex = regx
                      occ   = sy-index ).
      result = result + 1.
      WRITE AT result substr.
    ENDDO.

Description

In the text field text all the occurrences are searched for (using count and find) that correspond to a regular expression. When a search is successful, the subfield found is read out and displayed with the help of the match function.

Instead of using the count function, you could also use an unlimited DO loop that is left using EXIT if the result of find has the value -1.
