Jsoup - 如何通过逃避不删除不需要的HTML来清理html？

import org.jsoup.Jsoup;
import org.jsoup.safety.Cleaner;
import org.jsoup.safety.Whitelist;

public class JsoupExample {
    public static void main(String[] args) {
        String html = "<h1>Hello, <span style=\"color:red\">Jsoup</span>!</h1>";
        String cleanHtml = cleanHtml(html);
        System.out.println("Original HTML: " + html);
        System.out.println("Cleaned HTML: " + cleanHtml);
    }

    public static String cleanHtml(String html) {
        // 创建一个Cleaner对象
        Cleaner cleaner = new Cleaner(new Whitelist().addTags("span"));

        // 使用Cleaner对象清理HTML
        String cleanHtml = cleaner.clean(html);

        return cleanHtml;
    }
}

Original HTML: <h1>Hello, <span style="color:red">Jsoup</span>!</h1>
Cleaned HTML: <span>Jsoup</span>
