getTextCharactersback to summary
public int getTextCharacters(int sourceStart, char[] target, int targetStart, int length) throws XMLStreamException

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;
}
XMLStreamException may be thrown if there are any XML errors in the underlying source. The "targetStart" argument must be greater than or equal to 0 and less than the length of "target", Length must be greater than 0 and "targetStart + length" must be less than or equal to length of "target".
Parameters
sourceStart:int

the index of the first character in the source array to copy

This method should be used when processing element-only content separated by white space.
Precondition: none
Postcondition: the current event is START_ELEMENT or END_ELEMENT and cursor may have moved over any whitespace event.
Essentially it does the following (implementations are free to optimized but must do equivalent processing): 

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