Method Detail

nextEvent

XMLEvent nextEvent()
                   throws XMLStreamException

Get the next XMLEvent

Throws:

XMLStreamException - if there is an error with the underlying XML.

NoSuchElementException - iteration has no more elements.

XMLEvent

hasNext

boolean hasNext()

Check if there are more events. Returns true if there are more events and false otherwise.

Specified by:

hasNext in interface java.util.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

XMLEvent

getElementText

java.lang.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

getProperty

java.lang.Object getProperty(java.lang.String name)
                             throws java.lang.IllegalArgumentException

Get the value of a feature/property from the underlying implementation

Parameters:

name - The name of the property

Returns:

The value of the property

Throws:

java.lang.IllegalArgumentException - if the property is not supported

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
