タグ スタックを使用すると、複雑な XML ドキュメントの SAX 解析をどのように簡素化できるでしょうか?

public class Tag {
    private String name;
    private int count;
   
    // Constructors and other methods
}

public class TagStack {
    private Stack<Tag> stack;
   
    // Constructors and other methods
}

public class ExampleHandler extends DefaultHandler {
    private TagStack tagStack;

    public ExampleHandler() {
        tagStack = new TagStack();
    }

    @Override
    public void startElement(String uri, String localName, String qName, Attributes atts) throws SAXException {
        Tag tag = new Tag(localName, 1);
        tagStack.push(tag);
    }

    @Override
    public void endElement(String uri, String localName, String qName) throws SAXException {
        Tag tag = tagStack.pop();
        if (tag.getCount() > 1) {
            tag.decCount();
            tagStack.push(tag);
        }
    }

    // Other methods...
}

TagStack tagStack = new TagStack();
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
parser.parse(inputStream, new ExampleHandler(tagStack));
