SAP ABAP JSON XML documentation, setup help and example usage

ARTICLE

JSON-XML - XML Representation of JSON
JSON XML is an SAP-specific representation of JSON data in XML format. The single values , arrays , and
objects in JSON are represented as followed in XML .

Single Values

Character-like values
"..." - str ... /str

Number values
... - num ... /num

Boolean values
true - bool true /bool
false - bool false /bool

Null values
null - null /

Data Structures

Arrays
[...] - array ... /array
The components of arrays, separated by commas, are mapped as subelements of the element array , but the type-specific mapping rule applies to each element.

Objects
{...} - object ... /object
The components of objects, separated by commas, are mapped as subelements of the element object . There are two representation methods:

"n":... - ... name="n" ... /...

"n":... - member name="n" ... ...

/... /member
In the shorter method, used by default, a component is mapped like an element of an array, with the name n added to the type-specific XML element of the component as the content of the attribute
name .
In the second longer method, the type-specific XML element of a component is nested in an additional element member , which then has the attribute name with the name of the component.

Notes

In the longer alternative for object components, each component in

JSON-XML is identified clearly by a member element. This can make it easier to distinguish objects of arrays if only partial fragments of JSON data are being edited.

The longer alternative for object components with member elements can be a better option for simple transformations , when ABAP data is serialized to JSON or deserialized from

JSON .

A JSON writer that renders JSON-XML to JSON accepts both alternatives for object components. A JSON reader that parses JSON data to JSON-XML creates the shorter variant by default. To create the longer variant with member elements, the method SET_OPTION of the interface IF_SXML_READER can be used to set the option IF_SXML_READER= CO_OPT_SEP_MEMBER .

Examples

The program DEMO_JSON_XML shows examples of the default JSON-XML representation of valid JSON

data.

For information about the rendering and parsing of JSON-XML representations in both alternatives for object components, see Object Components in JSON-XML .
