Remove HTML tags from a string

daniel_humberg — Wed, 16 Dec 2009 14:23:18 GMT

I have a string that contains a couple of HTML or XHTML tag, for example

 lv_my_string = '<p style="something">Hello <strong>World</strong>!</p>'.

For a special use case, I want to remove all HTML from that string and process only the plain text

 lv_my_new_string = 'Hello World!'.

Is there any method, function module, XSLT or anything else for that already?

Check

HRDSYS_CONVERT_FROM_HTML & SOTR_TAGS_REMOVE_FROM_STRING

Try using the followig FMs:

1. SOTR_TAGS_REMOVE_FROM_STRING

2. SWA_STRING_REMOVE_SUBSTRING

Thx for the help.

1. SOTR_TAGS_REMOVE_FROM_STRING => nice but not perfect. It removes also single characters like "<" and ">" from the text. I would have to encode them before, right?

2. HRDSYS_CONVERT_FROM_HTML => returns only an empty table in my test

3. SWA_STRING_REMOVE_SUBSTRING => what kind of delete pattern would I use?

Hi Daniel,

Hope this code solves your problem.


DATA : ipstr TYPE string,
       opstr1 type string,
       opstr2 type string,
       opstr TYPE string,
       len TYPE i VALUE 0,
       ch TYPE char1,
       num TYPE i VALUE 0,   "No of Characters to be taken
       pos TYPE char3,      "Position of Char in the Input String
       count(3) type n.
*Input string
ipstr = '<p style="something">Hello <strong>World</strong>!</p><br>I need the data.</br>How are you?'.

len = STRLEN( ipstr ).
  DO len TIMES.
*Char by Char
  ch = ipstr+pos(1).
  pos = pos + 1.
*Scan each char in input String for ">"
  FIND '>' IN ch IGNORING CASE.
  IF sy-subrc = 0.
count = count + 1.
endif.
  FIND '<' IN ch IGNORING CASE.
    IF sy-subrc = 0.
count = count + 1.
endif.
enddo.

  split ipstr at '>' INTO opstr opstr1.
    DO count TIMES.
  split opstr1 at '<' into opstr opstr1.

 concatenate opstr2 opstr into opstr2.
  split opstr1 at '>' into opstr opstr1.

ENDDO.
  WRITE :/ opstr2.

Please combine all the above posted code and hope thsi helps you..

I tested it with this code and works fine..

You can use some Regular Expressions -:)


DATA: message TYPE string.

message = '<p style="something">Hello <strong>World</strong>!</p>'.

REPLACE ALL OCCURRENCES OF REGEX '<[a-zA-Z\/][^>]*>' IN message with space.
WRITE:/ message.

Hi Daniel,

I tried using the FM (SWA_STRING_REMOVE_SUBSTRING) but I guess it is expecting a particular pattern which is not so apparent in your case. Iu2019ve written a small piece of code which you can try using in a FM or a PERFORM and that should do the trick. Please let me know if you have any questions.


PARAMETER: P_LINE(100).

TYPES: BEGIN OF TY_LINE,
         LINE(100),
       END OF TY_LINE.

DATA: T_LINE TYPE STANDARD TABLE OF TY_LINE,
      WA_LINE LIKE LINE OF T_LINE.

DATA: W_LINE(100),
      W_LEN(100),
      W_COUNT TYPE I,
      W_FLAG,
      W_FLAG1,
      W_I TYPE I.

W_COUNT = STRLEN( P_LINE ).

DO W_COUNT TIMES.
  IF P_LINE+W_I(1) = '<'.
    W_FLAG = 1.
    W_I = W_I + 1.
    IF NOT WA_LINE-LINE IS INITIAL.
      APPEND WA_LINE-LINE TO T_LINE.
      CLEAR WA_LINE.
    ENDIF.
    CONTINUE.

  ELSEIF P_LINE+W_I(1) = '>'.
    W_FLAG = 0.
    W_I = W_I + 1.
    CONTINUE.
  ENDIF.

  IF W_FLAG = 1.
    W_I = W_I + 1.
    CONTINUE.
  ELSE.
    CONCATENATE WA_LINE-LINE P_LINE+W_I(1) INTO WA_LINE-LINE.
    W_I = W_I + 1.
  ENDIF.

ENDDO.

LOOP AT T_LINE INTO WA_LINE.
  CONCATENATE W_LINE WA_LINE-LINE INTO W_LINE SEPARATED BY SPACE.

ENDLOOP.

SHIFT W_LINE LEFT DELETING LEADING SPACE.
WRITE: W_LINE.

Input:

<p style="something">Hello <strong>World</strong>!</p>

Output:

HELLO WORLD !

Regards,

Pritam

Hi Daniel,

I realized i made a typo while copying the code. The Do~Enddo code would go like this.


DO W_COUNT TIMES.
  IF P_LINE+W_I(1) = '<'.
    W_FLAG = 1.
    W_I = W_I + 1.
    CONTINUE.
  ENDIF.
 
  IF P_LINE+W_I(1) = '>'.
    W_FLAG = 0.
    W_I = W_I + 1.
    CONTINUE.
  ENDIF.

  IF W_FLAG = 1.
    W_I = W_I + 1.
    CONTINUE.
  ELSE.
    CONCATENATE WA_LINE-LINE P_LINE+W_I(1) INTO WA_LINE-LINE.
    W_I = W_I + 1.
  ENDIF.
 ENDDO.

Please try this let me know if you have any questions

Hi Daniel,

There is some formatting issue while posting this code using the symbol {<}.

Basically inside the Do loop the if condition is to be written twice. First time to check for {<} and if satisafied w_flag is set to "1" and second time to check for ">" and if satisfied w_flag is set to "0".
