Issue in removing garbage values from string in class

Former Member — Mon, 13 Apr 2015 08:46:27 GMT

Hi Experts,

I am facing some problem while reading XML attachment in class CL_DOCUMENT_BCS.

While reading contents_hex values I am getting garbage values like '0000000000000' at end of string.

I tried to convert the xstring values to string

and those values became '################################' .

But couldn't remove same using all standard process.

1) REPLACE all occurrences of '##' IN:

lv_string WITH ' ' .

2) TRANSLATE lv_string using '## '.

However if I copy same string to normal SE38 editor and apply above mentioned approach it works.

I searched relevant issues posted but couldn't find concrete solution for same.

Hi Sandeep,

Since it is the end of string, new line or horizontal tab is appearing as '#' values. Try the below code and see if it helps,

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>CR_LF IN lv_string WITH space.

Hi Athreya,

I have tried all below mentioned approach already.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>horizontal_tab IN lv_string WITH space.

CONDENSE lv_string.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>newline IN lv_string WITH space.

CONDENSE lv_string.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>cr_lf IN lv_string WITH space.

CONDENSE lv_string.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>vertical_tab IN lv_string WITH space.

CONDENSE lv_string.

none of them removed the garbage values.

Sandeep

Hi Sandeep,

Try to use the method xstring_to_solix in CL_DOCUMENT_BCS to convert the xstring into string.Apply the replace occurance rule and try.

Hi Kannan,

Thnx for your reply.

But as I mentioned in my question I am getting this xstring by reading contents_hex values, which is a solix table only.

Go into debug and find out the hex values of the # characters.

Hi Mathew,

They are appearing as '0000000000000'. As I mentioned in my question.

Right, so that is the hex value. This document explains how to remove the nulls.

Thnx a lot Matthew. It worked. However I am still clueless why Replace of all occurrence didn't work.

Because when you type # in the abap editor, that is 0x23 which isn't the same as the null char, 0x00.

Hi,

I'm glad you got the solution already, but if the correct attachment size (not including the hex nulls padded to the last entry of solix_tab, in other words) is known, I'd use CL_BCS_CONVERT=>SOLIX_TO_XSTRING( ).

cheers

Hi, maybe for someone will be interesting also this simple approach to remove this "garbage" character from string:

method remove_garbage_character.
  data lv_white_characters type string.
  lv_white_characters = cl_abap_char_utilities=>get_simple_spaces_for_cur_cp( ).
  data: lv_lenght type i,
        lv_i type i value 0.
  lv_lenght = strlen( lv_white_characters ).
  while lv_i < lv_lenght.
    replace all occurrences of lv_white_characters+lv_i(1) in cv_string with ''.
    lv_i = lv_i + 1.
  endwhile.
endmethod.

CV_STRING is Changing parameter - TYPE String.

Enjoy, Z
