Deserializing Empty Elements
This example demonstrates the deserialization of empty elements.

ABAP_SOURCE_CODE
ABAP_EXEC

ABAP_DESCRIPTION
An elementary data object, a structure and an internal table are transformed using the identity transformation ID into asXML and asJSON display formats. With asXML display format, the values of all elements are removed. With asJSON display format, only the components from objects and arrays can be removed.
After deserialization into the original ABAP data objects, the elementary data object and the internal table are initial. However, the empty element in the structure is interpreted as a missing component and the structure component retains its previous value. If the transformation option clear is used with the value 'all', all ABAP data objects are initialized.

Note
The modification of XML and JSON data using string processing is only shown here to make the example clearer. In productive programs, the APIs of class libraries for XML should be used.
