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 .
The handling of XML fragments in the statement
tt:value is supported in
simple transformations , but not in the statements
tt:write or
tt:read . In tt:value , the mapping rule for XML
fragments can be modified using certain values for the attribute
option .
XML fragments in byte strings with reference to the domain
XSDANY are not supported in transformations
for JSON .
