I parse a big xml document with Sax, I want to stop parsing the document when some condition establish? How to do?

推荐答案

创建一个SAXException的特化并抛出它（你不必创建自己的专业化但是它意味着您可以自己专门捕获并将其他SAXExceptions视为实际错误。）

Create a specialization of a SAXException and throw it (you don't have to create your own specialization but it means you can specifically catch it yourself and treat other SAXExceptions as actual errors).

public class MySAXTerminatorException extends SAXException {
    ...
}

public void startElement (String namespaceUri, String localName,
                           String qualifiedName, Attributes attributes)
                        throws SAXException {
    if (someConditionOrOther) {
        throw new MySAXTerminatorException();
    }
    ...
}
