XML

abap-util ships three different XML helpers, each tuned for a different scenario.

Quick Picker

Use case	Helper
Round-trip ABAP data (typed)	xml_stringify / xml_parse
Round-trip ABAP data including its RTTI metadata	xml_srtti_*
Build arbitrary XML by hand	Fluent builder

xml_stringify

Render any ABAP value into asXML (the native XSLT-based XML representation). Raises cx_xslt_serialization_error on failure.

DATA(lv_xml) = zabaputil_cl_util=>xml_stringify( ls_data ).

xml_parse

Inverse of xml_stringify. The target value type drives the deserialization.

zabaputil_cl_util=>xml_parse(
    xml = lv_xml
    any = ls_data ).

xml_srtti_stringify

Serialize value + type information in one go. Use this when the receiver does not know the target type at compile time (e.g. the Persistence service uses it).

DATA(lv_blob) = zabaputil_cl_util=>xml_srtti_stringify( data = ls_data ).

xml_srtti_parse

Inverse of xml_srtti_stringify. Returns a freshly created REF TO data whose runtime type matches the original.

DATA(lr_data) = zabaputil_cl_util=>xml_srtti_parse( rtti_data = lv_blob ).
ASSIGN lr_data->* TO FIELD-SYMBOL(<data>).

Fluent XML Builder

zabaputil_cl_util_xml lets you build an XML tree without writing a single string. Useful for hand-crafted SOAP envelopes, OData payloads or custom export formats.

Factory

DATA(lo_xml) = zabaputil_cl_util_xml=>factory( ).

Adding nodes

Method	Meaning
__( n )	Add a child node and descend into it
_( n )	Add a child node, stay on the current node
_if( when n ) / __if( when n )	Add (and descend) only if when = abap_true
n( name )	Navigate up to the nearest ancestor named name
n( )	Navigate up to the parent
n_root( )	Navigate to the root
n_prev( )	Navigate to the previously created node
p( n v )	Add an attribute to the current node

Each builder method also accepts:

• ns — XML namespace prefix
• a / v — convenience for a single attribute name/value
• p — table of (n v) pairs for multiple attributes

Stringify

DATA(lv_xml) = lo_xml->stringify(
    from_root = abap_true   " default
    indent    = abap_true ).

Example

DATA(lv_xml) =
  zabaputil_cl_util_xml=>factory( )
    ->__( n = 'orders' )
      ->__( n = 'order' a = 'id' v = '1' )
        ->_( n = 'customer' v = 'ACME' )
        ->_( n = 'amount'   v = '99.95' )
      ->n( 'orders' )
      ->__( n = 'order' a = 'id' v = '2' )
        ->_( n = 'customer' v = 'Globex' )
    ->n_root( )
    ->stringify( indent = abap_true ).

Produces:

<orders>
  <order id="1">
    <customer>ACME</customer>
    <amount>99.95</amount>
  </order>
  <order id="2">
    <customer>Globex</customer>
  </order>
</orders>
