Simple Transformation XML to ABAP Content of tag with subtrees to string field


I have an requirement in which I have to do a transformation from an XML file to an structure.

I need get the value of a tag that have subtrees and move that to a field in my structure.








Result expected in ABAP Structure:

field1 -> tag1

field2 -> tag2

field3 -> <TAG4>value4</TAG4><TAG5>value5</TAG5>

The contents of the tag TAG3 is variable, so I want to store it as a string.

Can I make this with Simple Transformation?

In my tests I can move only the value of each child tag for the given field structure.

This syntax dont work:

<TAG3 tt:value-ref="STRUCTURE.FIELD3"/>

Thanks and Regards,

Miguel Motta

    Hi Miguel

    Have a look at below snippets. Here I have tried to escape the text inside TAG3 so that it gets treated as single node during transformation.

    ABAP code

    1. DATA: BEGIN OF result,
    2. col1 TYPE string,
    3. col2 TYPE string,
    4. col3 TYPE string,
    5. END OF result.
    6. DATA: xml_string TYPE string VALUE
    7. '<ROOT> <TAG1>value1</TAG1> <TAG2>value2</TAG2> <TAG3> <TAG4>value4</TAG4> <TAG5>value5</TAG5> </TAG3> </ROOT>',
    8. part1 TYPE string,
    9. part2 TYPE string,
    10. part3 TYPE string.
    11. * Escape the text inside TAG3 tag
    12. FIND REGEX '(.*<TAG3>)(.*)(</TAG3>.*)' IN xml_string SUBMATCHES part1 part2 part3.
    13. IF sy-subrc EQ 0.
    14. part2 = escape( val = part2 format = cl_abap_format=>e_xml_text ).
    15. * REPLACE ALL OCCURRENCES OF '<' IN part2 WITH '&lt;'.
    16. * REPLACE ALL OCCURRENCES OF '>' IN part2 WITH '&gt;'.
    17. xml_string = part1 && part2 && part3.
    18. ENDIF.
    19. TRY.
    20. * Display xml
    21. cl_abap_browser=>show_xml( EXPORTING xml_string = xml_string ).
    22. * Deserialization
    24. SOURCE XML xml_string
    25. RESULT para = result.
    26. * Check result
    27. WRITE:/ 'COL1=', result-col1,
    28. / 'COL2=', result-col2,
    29. / 'COL3=', result-col3.
    30. CATCH cx_st_error.
    31. * Error handling
    32. MESSAGE 'Error in Simple Transformation'
    33. TYPE 'I' DISPLAY LIKE 'E'.
    34. ENDTRY.

    Transformation code

    <?sap.transform simple?>
    <tt:transform xmlns:tt="" template="temp" version="0.1">

    <tt:root name="PARA"/>

    <tt:template name="temp">
    <tt:value ref="PARA.COL1"/>
    <tt:value ref="PARA.COL2"/>
    <tt:value ref="PARA.COL3"/>

    Hello Miguel,

    does the following work?


    <tt:value ref="$structure.field3"/>


    Interpreting your syntax example, the result would probably be

    <TAG3 <TAG4>value4</TAG4><TAG5>value5</TAG5>/>

    which is not valid XML.

    Best regards,
