org.apache.axiom.util.stax.WrappedTextNodeStreamReader

{@link XMLStreamReader} implementation thatrepresents a text node wrapped inside an element. The text data is provided by a {@link java.io.Reader Reader}.

It will produce the following sequence of XML events:

START_DOCUMENT
START_ELEMENT
(CHARACTER)*
END_ELEMENT
END_DOCMENT

The class is implemented as a simple state machine, where the state is identified by the current event type. The initial state is START_DOCUMENT and the following transitions are triggered by {@link #next()}:

START_DOCUMENT → START_ELEMENT
START_ELEMENT → END_ELEMENT (if character stream is empty)
START_ELEMENT → CHARACTERS (if character stream is not empty)
CHARACTERS → CHARACTERS (if data available in stream)
CHARACTERS → END_ELEMENT (if end of stream reached)
END_ELEMENT → END_DOCUMENT

Additionally, {@link #getElementText()} triggers the following transition:

START_ELEMENT → END_ELEMENT

Note that since multiple consecutive CHARACTERS events may be returned, this "parser" is not coalescing.

        XMLStreamWriter xmlStreamWriter = StAXUtils.createXMLStreamWriter(writer);
        new StreamingOMSerializer().serialize(xmlStreamReader, xmlStreamWriter);
        xmlStreamWriter.flush();
        assertXMLEqual(expectedXML, writer.toString());
