javax.xml.stream Interface XMLEventReader
- 所有父接口:
- Iterator
- 所有已知实现子孙类:
- 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.

nextEvent
XMLEvent nextEvent() throws XMLStreamException
- Get the next XMLEvent
- 抛出异常:
XMLStreamException- if there is an error with the underlying XML.NoSuchElementException- iteration has no more elements.- 另请参见:
XMLEvent
hasNext
boolean hasNext()
- Check if there are more events.
Returns true if there are more events and false otherwise.
- 返回:
- 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().
- 抛出异常:
XMLStreamException- 另请参见:
XMLEvent
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.
- 抛出异常:
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.
- 抛出异常:
XMLStreamException- if anything other than space characters are encountered
getProperty
Object getProperty(String name) throws IllegalArgumentException
- Get the value of a feature/property from the underlying implementation
- 参数:
name- The name of the property- 返回:
- The value of the property
- 抛出异常:
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.
- 抛出异常:
XMLStreamException- if there are errors freeing associated resources
