Interface XMLEventReader

  • All Superinterfaces:
    Iterator
    All Known Implementing Classes:
    EventReaderDelegate


    public interface XMLEventReader
    extends Iterator
    This is the top level interface for parsing XML Events. It provides the ability to peek at the next event and returns configuration information through the property interface.
    Since:
    1.6
    Version:
    1.0

    • Method Detail

      • hasNext

        boolean hasNext()
        Check if there are more events. Returns true if there are more events and false otherwise.
        Specified by:
        hasNext in interface Iterator
        Returns:
        true if the event reader has more events, false otherwise
      • peek

        XMLEvent peek()
               throws XMLStreamException
        Check the next XMLEvent without reading it from the stream. Returns null if the stream is at EOF or has no more XMLEvents. A call to peek() will be equal to the next return of next().
        Throws:
        XMLStreamException

      • getElementText

        String getElementText()
                       throws XMLStreamException
        Reads the content of a text-only element. Precondition: the current event is START_ELEMENT. Postcondition: The current event is the corresponding END_ELEMENT.
        Throws:
        XMLStreamException - if the current event is not a START_ELEMENT or if a non text element is encountered
      • nextTag

        XMLEvent nextTag()
                  throws XMLStreamException
        Skips any insignificant space events until a START_ELEMENT or END_ELEMENT is reached. If anything other than space characters are encountered, an exception is thrown. This method should be used when processing element-only content because the parser is not able to recognize ignorable whitespace if the DTD is missing or not interpreted.
        Throws:
        XMLStreamException - if anything other than space characters are encountered
      • close

        void close()
            throws XMLStreamException
        Frees any resources associated with this Reader. This method does not close the underlying input source.
        Throws:
        XMLStreamException - if there are errors freeing associated resources
