Java. Sax parser. How to manually break parsing?

Question

Hello! Tell me please is it possible to break the process of parsing? I.e. exit this loop not reaching the end of document and corresponding event "endDocument" ?

Answer 1

Throw an exception in the handler and catch it in the code block where you started parsing:

try {
    ...
    xmlReader.parse();
} catch (SAXException e) {
    if (e.Cause instanceof BreakParsingException) {
        // we have broken the parsing process
        ....
    }
}

And in your DocumentHandler:

public void startElement(String namespaceURI,
                     String localName,
                     String qName,
                     Attributes atts)
              throws SAXException {
    // ...
    throw new SAXException(new BreakParsingException());
}

Answer 2

You have to throw a SAXException. In order to distiguish it from regular errors I would subclass it with my own Exception class
