推荐答案

public class CustomHandler extends DefaultHandler {

    private ArrayList<String> questionList;
    private boolean questionBuffering;
    private StringBuilder sb;



    @Override
    public void startDocument() throws SAXException {
    questionList = new ArrayList<String>();
    } 

    @Override
    public void endDocument() throws SAXException {
    } 

    @Override
    public void startElement(String namespaceURI, String localName, String qName, Attributes atts) throws SAXException {
        if (localName.equals("question")) {
            questionBuffering = true;
        }

    }


    @Override
    public void characters(char ch[], int start, int length) {
        if(questionBuffering) {
            sb.append(ch, start, length);
        }

    } 

    @Override
    public void endElement(String namespaceURI, String localName, String qName) throws SAXException {
        if (localName.equals("question")) {
            questionBuffering = false;
        questionList.add(sb.toString());
        }
    }

    public ArrayList<String> getResult() {
        return questionList;
        };
    }
}
