iXML Library - Parse
XML data is parsed by a validating XML parser, itself created using the iXML factory as follows:
DATA(ixml) = cl_ixml=>create( ).

...

DATA(parser) = ixml->create_parser(
istream = ...
document = ...
stream_factory = ... ).
The static type of the reference variable parser is then the interface IF_IXML_PARSER . The parser requires the following input parameters:

The input stream istream (to be parsed).

An XML document document

, to which the stream is parsed.

A factory stream_factory must be specified. This enables the parser to create appropriate streams if external sources are addressed in the parsed document.

A parser created in this way works like an iterator on the input stream.
XML data can be parsed to a DOM representation in a single action or sequential parsing can be used, where the parser stops after certain steps and passes control to the application.
Alongside the parsers created using CREATE_PARSER , the factory method CREATE_TOKEN_PARSER
can be used to create a token parser for direct parsing to ABAP data objects.

Note
A parser is only valid once for the associated input stream and the associated XML document. Once it has parsed the input stream to a document, the parser can be passed to the garbage collector. A parser cannot be reused for the same XML data or for any other data.
