asXML - Mapping of XML Fragments
asXML allows whole XML fragments (elements together with their subelements) to be mapped that exist
in ABAP in XML format and that are the content of data objects or of parts of data objects (such as
structure components or table rows). The data objects must have the type xstring and be declared with reference to the
domain XSDANY.
- When serialized, a data object of this type (or part of a data object) must contain the
UTF8 representation of a complete
XML fragment. The content of the root element of the XML fragment is passed unmodified to the XML element
for which the data object was created. If the name of the XML element is not the same as the name of
the root element of the XML fragment, the fragment name is used as the content of an attribute
asx:root that is assigned to the XML element. No attribute is created if the names are the same.
- When deserialized, an XML element that contains the attribute asx:root
must be assigned to a data object (or part of a data object) of this type. An XML fragment is created
in the data object that has the content of the attribute as a root element and whose content is inherited
unmodified from the XML element. If the attribute asx:root does not exist, the root element is given the name of the XML element.
The following restrictions apply:
- XML fragments whose elements do not contain attributes cannot be deserialized.
- XML fragments whose root element is in the standard namespace cannot be serialized or deserialized.
Notes
- An XML fragment that exists in a data object of type xstring and that
is not declared with reference to the domain XSDANY is formatted as the XML schema type xsd:base64Binary in accordance with the rules for
mapping elementary data types.
- An XML element that contains the attribute asx:root cannot be deserialized to data objects that are not declared with reference to the domain XSDANY.
