ABAP Simple Transformations

Question

Hi,
does anyone know if Simple Transformations can be used to trasfer an XML data to an object? (instance of a class?)
all examples I saw are for structs and tables only, and not object references..
Thanks,
Mirit.

Answer 1

Here's the sample code I used to check the ST:
the object class (includes the if_serializabe_object):
class Z_PERSON definition
  public
  final
  create public .
" public components of class Z_PERSON
" do not include other source files here!!!
public section.
  interfaces IF_SERIALIZABLE_OBJECT .
  interfaces Z_IF_ENTITY .
  interfaces Z_IF_PAYABLE .
  data SIMPLE_STRING type STRINGVAL .
  methods WRITE_PROG .
protected section.
" protected components of class Z_PERSON
" do not include other source files here!!!
private section.
" private components of class Z_PERSON
" do not include other source files here!!!
ENDCLASS.
CLASS Z_PERSON IMPLEMENTATION.
ENDCLASS.
the ST code:
'<'?sap.transform simple?'>'
'<'tt:transform xmlns:tt="http://www.sap.com/transformation-templates"'>'
  '<'tt:root name="ROOT" /'>'
  '<'tt:template'>'
    '<'tt:deserialize'>'
      '<'sapesourcing'>'
       ' <'objects'>'
          '<'object'>'
            '<'fields'>'
               '<'PERSON_NAME tt:value-ref=".ROOT.SIMPLE_STRING"/'>'
            '<'/fields'>'
          '<'/object'>'
        '<'/objects'>'
      '<'/sapesourcing'>'
    '<'/tt:deserialize'>'
  '<'/tt:template'>'
'<'/tt:transform'> '
the report which runs the transformation:
REPORT  z_test_simple_transformation.
TYPES: BEGIN OF ls_xml_line,    
              data(256) TYPE x,
            END OF ls_xml_line.
DATA:
      exc TYPE REF TO cx_root,
      lv_ixml TYPE REF TO if_ixml,

      lv_xml_output_stream TYPE REF TO if_ixml_ostream,
      lv_input_filepath TYPE string,
          lv_output_filepath TYPE string,
          lv_input_filelength TYPE i,
          lv_output_filelength TYPE i,
         lt_input_xml_table TYPE TABLE OF ls_xml_line,
         lt_output_xml_table TYPE TABLE OF ls_xml_line.
TRY.
    lv_output_filepath = 'C:\files\AmexGL1025\partial_GL1025_BoConverted_ABAP.xml'.
    cl_gui_frontend_services=>gui_upload( EXPORTING filename   = lv_output_filepath
                                                    filetype   = 'BIN'
                                          IMPORTING filelength =  lv_output_filelength
                                          CHANGING  data_tab   = lt_input_xml_table ).
    lv_ixml = cl_ixml=>create( ).
    lv_xml_stream_factory = lv_ixml->create_stream_factory( ).
    lv_xml_input_stream =  lv_xml_stream_factory->create_istream_itable( table = lt_input_xml_table   size = lv_output_filelength ).
    DATA lo_testing_object TYPE REF TO z_person.
    CREATE OBJECT lo_testing_object TYPE z_person.
    CALL TRANSFORMATION Z_simple_transformation_test SOURCE XML lv_xml_input_stream RESULT root = lo_testing_object .
  CATCH cx_root INTO exc.
    DATA lv_error_message TYPE string.
    lv_error_message = exc->get_text( ).
    WRITE lv_error_message.
ENDTRY.
I don't know why the indentation here is so awful.
If you can see what the bug is- it will be great...
Thanks!
