Add node into XML stream

[former_member663465]

Hi all,

i need to add to an existing xml stream a node on the top of the xml.

Example XML source:

<?xml version="1.0" encoding="UTF-8"?>
<Content>
	<Email>test@gmail.com</Email>
</Content>

Example XML destination:

<?xml version="1.0" encoding="UTF-8"?>
<metadata>
	<IP>182.235.32.00</IP>
</metadata>
<Content>
	<Email>test@gmail.com</Email>
</Content>

I think we should use the class if_ixml but sincerely i don't know how to write my need.

I hope you can help me 🙂

Your "XML destination" is not valid, there can be only a unique root element. Valid XML example:

<?xml version="1.0" encoding="UTF-8"?>
<Content>
  <IP>182.235.32.00</IP>
  <Email>test@gmail.com</Email>
</Content>

With iXML, to go from:

<?xml version="1.0" encoding="UTF-8"?>
<Content>
  <Email>test@gmail.com</Email>
</Content>

to (new "IP" element):

<?xml version="1.0" encoding="utf-8"?>
<Content>
  <IP>182.235.32.00</IP>
  <Email>test@gmail.com</Email>
</Content>

this code can be used:

DATA(lo_ixml) = cl_ixml=>create( ).
DATA(lo_streamfactory) = lo_ixml->create_stream_factory( ).
DATA(lo_document) = lo_ixml->create_document( ).

DATA(lo_parser) = lo_ixml->create_parser(
        stream_factory = lo_streamfactory
        istream        = lo_streamfactory->create_istream_string(
                             '<?xml version="1.0" encoding="UTF-8"?>'
                          && '<Content>'
                          && '  <Email>test@gmail.com</Email>'
                          && '</Content>' )
        document       = lo_document ).
lo_parser->parse( ).

DATA(lo_element) = lo_document->create_element( name = 'IP' ).
lo_element->set_value( '182.235.32.00' ).
lo_document->find_from_name( name = 'Content')->insert_child(
        new_child = lo_element
        ref_child = lo_document->find_from_name( name = 'Email') ).

DATA(l_xstring) = VALUE xstring( ).
DATA(lo_ostream) = lo_streamfactory->create_ostream_xstring( l_xstring ).
DATA(lo_renderer) = lo_ixml->create_renderer(
        ostream  = lo_ostream
        document = lo_document ).
lo_renderer->render( ).

DATA(string) = cl_abap_codepage=>convert_from( l_xstring ).
ASSERT string =
        '<?xml version="1.0" encoding="utf-8"?>'
     && '<Content>'
     && '<IP>182.235.32.00</IP>'
     && '<Email>test@gmail.com</Email>'
     && '</Content>'.
