爪哇.萨克斯解析器.如何手动中断解析? [英] Java. Sax parser. How to manually break parsing?

问题描述

请告诉我是否可以中断解析过程?IE.退出这个循环没有到达文档的结尾和相应的事件endDocument"?

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" ?

推荐答案

在处理程序中抛出异常并在您开始解析的代码块中捕获它:

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
        ....
    }
}

在你的 DocumentHandler 中:

And in your DocumentHandler:

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