如何在不使用Jsoup的情况下解析html文件？

import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.parser.ParserDelegator;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.StringReader;

public class HTMLParser {
    public static void main(String[] args) {
        String htmlFilePath = "path/to/html/file.html";
        String htmlContent = readHTMLFile(htmlFilePath);
        parseHTML(htmlContent);
    }

    private static String readHTMLFile(String filePath) {
        StringBuilder content = new StringBuilder();
        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                content.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return content.toString();
    }

    private static void parseHTML(String htmlContent) {
        HTMLEditorKit.ParserCallback callback = new HTMLEditorKit.ParserCallback() {
            public void handleText(char[] data, int pos) {
                System.out.println(new String(data));
            }
        };
        try {
            new ParserDelegator().parse(new StringReader(htmlContent), callback, true);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
