Hi Horst,

I am using below code:

lv_string3 = 'DeletedECN STATUS="0" TYPE="Unknown" NAME="DeletedECN"'.

ref3_ixml_element = ref_ixml_document->create_element(

name = lv_string3 ).

ref_ixml_node_parent->append_child( new_child = ref3_ixml_element ).

through which i am getting

Hi,

Some code based on solution

*----------------------------------------------------------------------*

FORM test_03 .

DATA: ob_ixml TYPE REF TO if_ixml . " Interface of Factory Object

DATA: ob_ixml_document TYPE REF TO if_ixml_document, " XML Document in DOM Representation

ob_ixml_encoding TYPE REF TO if_ixml_encoding. " Character Encoding

ob_ixml = cl_ixml=>create( ).

ob_ixml_document = ob_ixml->create_document( ).

DATA: ob_ixml_element TYPE REF TO if_ixml_element . " Element of an XML Document

ob_ixml_element = ob_ixml_document->create_simple_element(

name = 'DeletedECN'

parent = ob_ixml_document ) .

ob_ixml_element->set_attribute( EXPORTING name = 'TYPE' value = 'Unknown' ) .

ob_ixml_element->set_attribute( EXPORTING name = 'NAME' value = 'DeletedECN' ) .

* ob_ixml_element->set_value( ' ' ) .

DATA: ob_ixml_stream_factory TYPE REF TO if_ixml_stream_factory. " Factory for Streams

DATA: ob_ostream TYPE REF TO if_ixml_ostream . " Output Streams

DATA: debug TYPE string.

* For debug purpose only

ob_ixml_stream_factory = ob_ixml->create_stream_factory( ).

ob_ostream = ob_ixml_stream_factory->create_ostream_cstring( debug ).

ob_ostream->set_pretty_print( abap_true ).

ob_ixml_document->render( ostream = ob_ostream ) .

* At this point we have XML

* Look at debug using the XML view .

* See the content of count vs the XML output using tabular view

BREAK-POINT .

ENDFORM.

Hi Eitan,

thank you for your reply.

i understood your solution.

but i am unable to get last closing node i.e. </DeletedECN>

<DeletedECN STATUS="0" TYPE="Unknown" NAME="DeletedECN"> </DeletedECN>..

how can i achieve this.

Thanks,

Darshan.

Hi Darshan,

I have faced this issue before. What I observed is, SAP uses a "self-closing tag" in case there are no elements under the node. I haven't found out a setting on SAP to make it generate a closing tag.

Thanks, Juwin

Look at the picture from Eitan. The Tag is closed at the end, it does not need to have separate closing...

Re: XML structure

Juwin — Wed, 16 Mar 2016 12:37:07 GMT

Yes, syntactically, XML is correct. But, in my case, Bank wasn't accepting that kind of tag. They wanted an explicit closing tag and not a 'self-closing' tag. And, that's what I think OP wants to achieve as well.

Thanks,

Juwin

Hi,

This is a valid XML .

Since you do no use any value there is no closing tag .

If you use it:

You get:

There might be an option to force the ob_ostream to produce a closing tag but I do not see it.

Regards.

Juwin — Wed, 16 Mar 2016 12:47:22 GMT

Hi ,

That's a nice trick. I would just suggest to replace the value *, with a new line character, so that the receiver doesn't know that the closing tag was forced. Plus adding a new line character, it doesn't visually add a new value to the file at all.

Thanks,

Juwin

rosenberg_eitan — Wed, 16 Mar 2016 13:02:19 GMT

Good one

Re: XML structure

Juwin — Wed, 16 Mar 2016 13:02:54 GMT

Add one more attribute just like he has given in the sample code:

ob_ixml_element->set_attribute( exporting name = 'STATUS' value = '0' )

Thanks,

Juwin

Re: XML structure

rosenberg_eitan — Wed, 16 Mar 2016 13:09:33 GMT

Hi,

I really think that you have to use advise.

ob_ixml_document->get_elements_by_tag_name( name = 'Tag name' ).

Regards.

Or better add some unique dummy value like "[SAP_DUMMY]".

And clear it from XLM string at the end.

Re: XML structure

Hi Darshan,

It does appear. Complete code is:

39 write debug.

With the newline character, there is no need to do a replace/ clear at the end. So, isn't that actually better?

Thanks, Juwin

Hi juwin,

I am using show_xml for display..

ref12_ixml_element = ref_ixml_document->create_simple_element(

name = 'DeletedAlternateLinks '

parent = ref_ixml_document ).

ref12_ixml_element->set_attribute( EXPORTING name = 'STATUS' value = '0' ) .

ref12_ixml_element->set_attribute( EXPORTING name = 'TYPE' value = 'Unknown' ) .

ref12_ixml_element->set_attribute( EXPORTING name = 'Name' value = 'DeletedAlternateLinks ' ) .

ref12_ixml_element->set_value( c_newline ).

ref_ixml_node_parent->append_child( new_child = ref12_ixml_element ).

Thanks,

Darshan

This could be a display issue with the viewer. Open the downloaded XML file, using a notepad and then check for the closing tags in notepad.

Thanks, Juwin
