[ABAP] XML-Strings parsen

Variante 1 (IF_IXML_ELEMENT, IF_IXML_NODE_COLLECTION)

* XML-Daten
DATA(lv_xml) = |<object>| &&
               |  <str name="text">abcd</str>| &&
               |  <bool name="flag">true</bool>| &&
               |  <member name="number"><num>111</num></member>| &&
               |  <member name="content"><null /></member>| &&
               |  <member name="attr"></member>| &&
               |</object>|.

* XML-Interface
DATA(o_ixml) = cl_ixml=>create( ).
* XML-Doc
DATA(o_doc) = o_ixml->create_document( ).
* Stream-Factory
DATA(o_sf) = o_ixml->create_stream_factory( ).
* Stream
DATA(o_stream) = o_sf->create_istream_string( string = lv_xml ).

* Parser-Objekt erzeugen
DATA(o_parser) = o_ixml->create_parser( document       = o_doc
                                        istream        = o_stream
                                        stream_factory = o_sf ).

* XML parsen
IF o_parser->parse( ) = 0.
* Root-Node
  DATA(o_root) = o_doc->get_root_element( ).

* Alle Nodes mit Namen 'member'
  DATA(o_nodes_member) = o_root->get_elements_by_tag_name( name = 'member' ).
* Iterator für die gefundenen Nodes
  DATA(o_node_iterator_members) = o_nodes_member->create_iterator( ).
* ersten Iterator-Wert holen
  DATA(o_nodes_temp) = o_node_iterator_members->get_next( ).

* Iterator durchgehen
  WHILE NOT o_nodes_temp IS INITIAL.
* Wert der Node ausgeben
    WRITE: / o_nodes_temp->get_value( ).

* Attribute
    DATA(o_note_temp_attr) = o_nodes_temp->get_attributes( ).
    DATA(o_node_temp_item) = o_note_temp_attr->get_named_item( 'name' ).

* nächster Iterator-Wert
    o_nodes_temp = o_node_iterator_members->get_next( ).
  ENDWHILE.
ELSE.
* Fehlerauswertung
  DO o_parser->num_errors( ) TIMES.
    DATA(o_err) = o_parser->get_error( index = sy-index - 1 ).
    IF o_err IS BOUND.
      WRITE: / o_err->get_column( ), o_err->get_line( ), o_err->get_reason( ).
    ENDIF.
  ENDDO.
ENDIF.

Variante 2 (find_from_name)

* XML-Daten
DATA(lv_xml) = |<object>| &&

* XML-Interface
DATA(o_ixml) = cl_ixml=>create( ).
* XML-Doc
DATA(o_doc) = o_ixml->create_document( ).
* Stream-Factory
DATA(o_sf) = o_ixml->create_stream_factory( ).
* Stream
DATA(o_stream) = o_sf->create_istream_string( string = lv_xml ).

* Parser-Objekt erzeugen
DATA(o_parser) = o_ixml->create_parser( document       = o_doc
                                        istream        = o_stream
                                        stream_factory = o_sf ).

* XML parsen
IF o_parser->parse( ) = 0.
* <object>
  DATA(o_root) = o_doc->find_from_name( 'object' ).

  IF o_root IS BOUND.
* <str ...>
    DATA(o_str) = o_root->get_first_child( ).
    IF o_str IS BOUND.
* Wert der Node ausgeben
      WRITE: / o_str->get_value( ).

* Attribut 'name'
      DATA(o_attr) = o_str->get_attributes( ).
      DATA(o_name) = o_attr->get_named_item( 'name' ).
      IF o_name IS BOUND.
        WRITE: / o_name->get_value( ).
      ENDIF.
    ENDIF.
  ENDIF.
ELSE.
* Fehlerauswertung
  DO o_parser->num_errors( ) TIMES.
    DATA(o_err) = o_parser->get_error( index = sy-index - 1 ).
