Doc from javax.xml.stream.XMLStreamReader.getNamespaceCount.

Returns the count of namespaces declared on this START_ELEMENT or END_ELEMENT, this method is only valid on a START_ELEMENT, END_ELEMENT or NAMESPACE. On an END_ELEMENT the count is of the namespaces that are about to go out of scope. This is the equivalent of the information reported by SAX callback for an end element event.

Implements javax.xml.stream.XMLStreamReader.getNamespacePrefix.

Exceptions

IllegalArgumentException:

if name is null

Implements javax.xml.stream.XMLStreamReader.getText.

Doc from javax.xml.stream.XMLStreamReader.getText.

Returns the current value of the parse event as a string, this returns the string value of a CHARACTERS event, returns the value of a COMMENT, the replacement value for an ENTITY_REFERENCE, the string value of a CDATA section, the string value for a SPACE event, or the String value of the internal subset of the DTD. If an ENTITY_REFERENCE has been resolved, any character data will be reported as CHARACTERS events.

Implements javax.xml.stream.XMLStreamReader.getTextCharacters.

Doc from javax.xml.stream.XMLStreamReader.getTextCharacters.

Returns an array which contains the characters from this event. This array should be treated as read-only and transient. I.e. the array will contain the text characters until the XMLStreamReader moves on to the next event. Attempts to hold onto the character array beyond that time or modify the contents of the array are breaches of the contract for this interface.

Implements javax.xml.stream.XMLStreamReader.getTextCharacters.

Doc from javax.xml.stream.XMLStreamReader.getTextCharacters.

Gets the text associated with a CHARACTERS, SPACE or CDATA event. Text starting a "sourceStart" is copied into "target" starting at "targetStart". Up to "length" characters are copied. The number of characters actually copied is returned. The "sourceStart" argument must be greater or equal to 0 and less than or equal to the number of characters associated with the event. Usually, one requests text starting at a "sourceStart" of 0. If the number of characters actually copied is less than the "length", then there is no more text. Otherwise, subsequent calls need to be made until all text has been retrieved. For example:

int length = 1024;
char[] myBuffer = new char[ length ];

for ( int sourceStart = 0 ; ; sourceStart += length )
{
   int nCopied = stream.getTextCharacters( sourceStart, myBuffer, 0, length );

  if (nCopied < length)
      break;
}

returns a boolean indicating whether the current event has a name (is a START_ELEMENT or END_ELEMENT).

Implements javax.xml.stream.XMLStreamReader.hasNext.

Doc from javax.xml.stream.XMLStreamReader.hasNext.

Returns true if there are more parsing events and false if there are no more events. This method will return false if the current state of the XMLStreamReader is END_DOCUMENT

Exceptions

Implements javax.xml.stream.XMLStreamReader.isWhiteSpace.

Doc from javax.xml.stream.XMLStreamReader.isWhiteSpace.

Returns true if the cursor points to a character data event that consists of all whitespace

Implements javax.xml.stream.XMLStreamReader.next.

Doc from javax.xml.stream.XMLStreamReader.next.

Get next parsing event - a processor may return all contiguous character data in a single chunk, or it may split it into several chunks. If the property javax.xml.stream.isCoalescing is set to true element content must be coalesced and only one CHARACTERS event must be returned for contiguous element content or CDATA Sections. By default entity references must be expanded and reported transparently to the application. An exception will be thrown if an entity reference cannot be expanded. If element content is empty (i.e. content is "") then no CHARACTERS event will be reported.

Given the following XML:
<foo><!--description-->content text<![CDATA[<greeting>Hello>/greeting>]]>other content>/foo>
The behavior of calling next() when being on foo will be:
1- the comment (COMMENT)
2- then the characters section (CHARACTERS)
3- then the CDATA section (another CHARACTERS)
4- then the next characters section (another CHARACTERS)
5- then the END_ELEMENT

Exceptions

XMLStreamException:

if there is an error processing the underlying XML source

Implements javax.xml.stream.XMLStreamReader.nextTag.

Doc from javax.xml.stream.XMLStreamReader.nextTag.

Skips any white space (isWhiteSpace() returns true), COMMENT, or PROCESSING_INSTRUCTION, until a START_ELEMENT or END_ELEMENT is reached. If other than white space characters, COMMENT, PROCESSING_INSTRUCTION, START_ELEMENT, END_ELEMENT are encountered, an exception is thrown. This method should be used when processing element-only content separated by white space.

 int eventType = next();
while((eventType == XMLStreamConstants.CHARACTERS && isWhiteSpace()) // skip whitespace
|| (eventType == XMLStreamConstants.CDATA && isWhiteSpace())
// skip whitespace
|| eventType == XMLStreamConstants.SPACE
