I'm using if_ixml class to create xml documents
TYPES: BEGIN OF xml_line,
         data(256) TYPE x,
       END OF xml_line.
DATA: o_ixml          TYPE REF TO if_ixml,
      o_document      TYPE REF TO if_ixml_document,
      o_element       TYPE REF TO if_ixml_element,
      o_streamfactory TYPE REF TO if_ixml_stream_factory,
      o_ostream       TYPE REF TO if_ixml_ostream,
      o_renderer      TYPE REF TO if_ixml_renderer.
DATA: t_xml_table     TYPE TABLE OF xml_line,
      v_xml_size      TYPE i.
o_ixml = cl_ixml=>create( ).
o_document = o_ixml->create_document( ).
* The o_document have a set of methods to add elements, attributes, etc.
o_element  = o_document->create_simple_element(
                  name = 'RootNode'
                  value = 'some text'
                  parent = o_document ).
o_streamfactory = o_ixml->create_stream_factory( ).
o_ostream = o_streamfactory->create_ostream_itable( table = t_xml_table ).
o_renderer = o_ixml->create_renderer( ostream  = o_ostream document = o_document ).
o_renderer->render( ).
v_xml_size = o_ostream->get_num_written_raw( ).
CALL METHOD cl_gui_frontend_services=>gui_download
  EXPORTING
    bin_filesize = v_xml_size
    filename     = 'C:a.xml'
    filetype     = 'BIN'
  CHANGING
    data_tab     = t_xml_table.
