ABAP_ST - tt:value, Structures

ABAP_SYNTAX
< tt:value $[ref='node'$] $[map='...'$]
$[length$|minLength$|maxLength='len'$]
$[xsd-type...$] />

What does it do?
The serialization and deserialization of structures results directly from the addressing rules, because the structures can be mapped directly to the tree structures that start from the data roots. When the current node is bound to an elementary component of an ABAP structure, the structure can be processed with tt:value just like an elementary data object.

ABAP_EXAMPLES
The three ST programs from the sections

Current Node

Addressing the Current Node

Addressing Subnodes
can transform a nested ABAP structure symmetrically . The following program can call these three ST programs: DATA: BEGIN OF struc1,
col1(10) TYPE c VALUE 'ABCDEFGHIJ',
col2 TYPE i VALUE 111,
BEGIN OF struc2,
col1 TYPE d VALUE '20040126',
col2 TYPE t VALUE '084000',
END OF struc2,
END OF struc1.

DATA: xml_string TYPE string,
result LIKE struc1.

TRY.
CALL TRANSFORMATION ...
SOURCE root = struc1
RESULT XML xml_string.
cl_abap_browser=>show_xml( EXPORTING xml_string = xml_string ).
CALL TRANSFORMATION ...
SOURCE XML xml_string
RESULT root = result.
IF struc1 <> result.
MESSAGE 'Deserialization <> Serialization' TYPE 'I'.
ENDIF.
CATCH cx_st_error.
...
ENDTRY.
The result of the serialization is the same XML data for all three Simple Transformations: < X >
< X1>ABCDEFGHIJ < /X1>
< X2>111 < /X2>
< X3>
< X1>2004-01-26 < /X1>
< X2>08:40:00 < /X2>
< /X3>
< /X>
