Get next parsing event - a processor may return all contiguous character data in a single chunk, or it may split it into several chunks.

Usage

From source file:Main.java

public static String nextString(XMLStreamReader reader) throws XMLStreamException {
    int type;//  ww w.j  a v  a 2 s.  c  o  m
    StringBuilder result = new StringBuilder();

        switch (type) {
        case XMLStreamReader.START_ELEMENT:
            throw new IllegalStateException("Found start element parsing text.");

        case XMLStreamReader.CDATA:
        case XMLStreamReader.SPACE:
        case XMLStreamReader.CHARACTERS:
            result.append(reader.getText());
        }
