* Philippe Le Hégaret | | charecters takes an array of characters for the data : | | public abstract void characters(char ch[], | int start, | int length) throws SAXException | | processingInstruction takes a String for the data : | | public abstract void processingInstruction(String target, | String data) throws SAXException | | Why is there this difference in SAX ? I wasn't "present" when this decision was made, but I'd guess characters is the way it is because this way is faster in most implementations, since most parsers keep a character buffer during parsing and this avoids unecessary buffer copying. However, doing it this way is obviously less convenient for the user, who would prefer to just get a String and be done with it. I guess this is why the current form of processingInstruction was chosen, since processing instructions rarely occur often in documents and thus performance is less of an issue.
