如何对div中的特定元素通过jsoup进行打包？

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

public class JsoupExample {
    public static void main(String[] args) {
        String html = "<div id=\"container\">" +
                "<h1>Title</h1>" +
                "<p>Paragraph 1</p>" +
                "<p>Paragraph 2</p>" +
                "<p>Paragraph 3</p>" +
                "</div>";

        Document doc = Jsoup.parse(html);
        Element container = doc.getElementById("container");
        Elements paragraphs = container.getElementsByTag("p");

        StringBuilder packagedContent = new StringBuilder();
        for (Element paragraph : paragraphs) {
            packagedContent.append(paragraph.text()).append(" ");
        }

        System.out.println("Packaged Content: " + packagedContent.toString());
    }
}

Packaged Content: Paragraph 1 Paragraph 2 Paragraph 3
