Closing tag in xml transformation

Hi experts,

I have the following ABAP code:


  • ABAP itab to XML string

CALL TRANSFORMATION id SOURCE data = ti_stocks[]

RESULT XML ps_output.


The result in ps_output should be an xml like this

<?xml version="1.0" encoding="utf-16" ?>" version="1.0">





<FIELD2 />0300</FIELD2>

<FIELD3 />1</FIELD3>



However, if my internal table ti_stocks contains the field1 with an empty value then the xml is incorrect without its corresponding closing tag:

<?xml version="1.0" encoding="utf-16" ?>" version="1.0">




<FIELD1 />

<FIELD2 />0300</FIELD2>

<FIELD3 />1</FIELD3>



How can I resolve this problem? I would like to have an open tag and a closing tag for every field.

FIELD1 is a char type field.

Thank you,

    Since Field1is a char type, assign blank space explicitly if it has blank value.

    Then transform it into XML and check it out.

    I don't see the problem.


    is technically the same as

    <tag />

    • Hello everyone, sorry for my english, I had the same requeriment for the end tag, the simple transformation give this result <xxx/> when the value was empty, and I did something similar to Oscar,

      i did the simple transformation and the result whas and xstring, i used a function to pass it to string, and then I make a replacement.

      here is some code:

      * Genera XML

      data: xml_xstring type xstring.

      data: w_xml type string.

      data: ixml type ref to if_ixml,

      streamfactory type ref to if_ixml_stream_factory,

      encoding type ref to if_ixml_encoding,

      ixml_ostream type ref to if_ixml_ostream.

      data: resstream type ref to if_ixml_ostream.

      ****Create an instance of the Ixml Processor

      ixml = cl_ixml=>create( ).

      * ****Create the Stream Factory

      streamfactory = ixml->create_stream_factory( ).

      * ****Create an Endcoding and Byte Order

      encoding = ixml->create_encoding( character_set = 'ISO-8859-1' byte_order = 0 ).

      * * ****Create the output stream with a pointer to our binary string

      ixml_ostream = streamfactory->create_ostream_xstring( xml_xstring ).

      * ****Set the Encoding into a stream

      ixml_ostream->set_encoding( encoding = encoding ).

      ****Call simple Transformation

      call transformation zdte_libros

      source zcaratula = x_doc

      result xml ixml_ostream.

      *From xstring to string.

      call function 'HR_RU_CONVERT_HEX_TO_STRING'


      xstring = xml_xstring


      cstring = w_xml.

      * <xxx/> to <xxx><xxx/>

      replace all occurrences of regex '<([^><\s]+)( [^><]+)?/>' in w_xml with '<$1$2></$1>'.

      Hope it helps someone with the same problem 😊.
