Converting hexadecimal XML data to a string

martin_kukielka — Tue, 02 Sep 2008 17:02:19 GMT

Hello!

Until now I generated XML data with the FM 'SDIXML_DOM_TO_XML'.

After that I did a loop over the xml_as_table in which I was casting each line of that table to a string.

ASSIGN <line> TO <line_c> CASTING.

After the inftroduction of unicode in our system I get a error:

In the current program an error occured when setting the field symbol <LINE_C> with ASSIGN or ASSIGNING (maybe in combination with the CASTING addition).

When converting the base entry of the field symbol <LINE_C> (number in base table: 32776), it was found that the target type requests a memory alignment of 2

What does it mean? Does somebody have a solution.

I need this function for sending this XML data as string over a simple old CPIC connection.

Best regards

Martin

Hello Martin

Perhaps my sample report ZUS_SDN_XML_XSTRING_TO_STRING provides a solution for your problem.

Hello Uwe,

I just used the last part of your example coding and it works. Thanks!

Here is my ready code snipplet:

CALL FUNCTION 'SDIXML_DOM_TO_XML'
       EXPORTING
            document      = m_document
            pretty_print  = 'X'
       IMPORTING
            xml_as_string = w_string
            size          = w_size
       TABLES
            xml_as_table  = it_xml
       EXCEPTIONS
            no_document   = 1
            OTHERS        = 2.
  IF sy-subrc = 0.
*    WRITE  'ok'.
  ELSE.
    WRITE: 'Err =', sy-subrc.
  ENDIF.

  create object go_xml_doc.
  CALL METHOD go_xml_doc->parse_table
    EXPORTING
      table   = it_xml
*      size    = 0
    receiving
      retcode = gd_rc.
  CALL METHOD go_xml_doc->render_2_string
*    EXPORTING
*      pretty_print = 'X'
    IMPORTING
      retcode      = gd_rc
      stream       = gd_xml_string
*      size         =
      .

Now the string variable gd_xml_string contains the XML stream which I'm able to split into a table.

SPLIT gd_xml_string AT CL_ABAP_CHAR_UTILITIES=>NEWLINE INTO TABLE write_table IN CHARACTER MODE.

Each line of the table is now send over CPIC and it works.

Best regards

Martin

Hello Martin

If you want to retrieve the XML stream as itab then you could use another method:


  CALL METHOD go_xml_doc->render_2_table
*    EXPORTING
*      pretty_print = 'X'
    IMPORTING
      retcode      = gd_rc
      table          = write_table
*      size         =
      .
