    you can look at the coding example

    data: event type ref to if_ixml_event,

    event_sub type i

    lp_dom type ref to if_ixml_document,

    pstreamfac TYPE REF TO if_ixml_stream_factory,

    pistream TYPE REF TO if_ixml_istream,


    • create the factory for streams

    pstreamfac = g_ixml->create_stream_factory( ).

    • create the input stream:

    pistream = pstreamfac->create_istream_cstring( string = xml ).

    lp_dom = g_ixml->create_document( ).

    • create the iXML parser:

    parser = g_ixml->create_parser(

    stream_factory = pstreamfac

    istream = pistream

    document = lp_dom ).

    • let the parser know which events I am interested in

    event_sub = if_ixml_event=>co_event_element_pre2 +


    parser->set_event_subscription( events = event_sub ).


    event = parser->parse_event( ).

    if event is initial.

    exit. ' either end reached or error (check below)


    data: str type string.

    case event->get_type( ).

    when if_ixml_event~co_event_element_pre2.

    str = event->get_name( ). write: '<' str '>'.

    when if_ixml_event~co_event_text_post.

    str = event->get_value( ). write: str.




    • always check for errors:

    if parser->num_errors( ) ne 0.

    • Hi!

      When you are using iXML in an event-based way I suggest to disable implicit generation of the whole DOM-Tree:

      CALL METHOD l_rif_pparser->set_dom_generating


      is_generating = space


      rval = l_var_rval.

      Hope that helps!
