Java 抓取网页导演信息：使用 Jsoup 库解析 HTML

可以使用 Jsoup 库来解析 HTML 代码，然后使用 CSS 选择器来获取导演信息。示例代码如下：

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

public class Main {
    public static void main(String[] args) {
        String html = '<div class="list-wrapper">
' + "        <h2>导演 Director</h2>
" + "        
" + "
" + '<ul class="celebrities-list  __multiline">
' + "
" + "  
" + "    
" + "
" + "  
" + "  <li class="celebrity">
" + "    
" + "
" + "  <a href="https://movie.douban.com/celebrity/1276086/" title="郭帆 Frant Gwo" class="">
" + "      <div class="avatar" style="background-image: url(https://img9.doubanio.com/view/personage/raw/public/300a2139dffdb8cd3eba50101766a4e4.jpg)">
" + "    </div>
" + "  </a>
" + "
" + "    <div class="info">
" + "      <span class="name"><a href="https://movie.douban.com/celebrity/1276086/" title="郭帆 Frant Gwo" class="name">郭帆 Frant Gwo</a></span>
" + "
" + "      <span class="role" title="导演 Director">导演 Director</span>
" + "
" + "        <span class="works">
" + "          代表作：
" + "          
" + "            <a href="https://movie.douban.com/subject/26266893/" target="_blank" title="流浪地球">流浪地球</a>
" + "          
" + "            <a href="https://movie.douban.com/subject/35267208/" target="_blank" title="流浪地球2">流浪地球2</a>
" + "          
" + "            <a href="https://movie.douban.com/subject/27110296/" target="_blank" title="无名之辈">无名之辈</a>
" + "        </span>
" + "    </div>
" + "  </li>
" + '</ul></div>';

        Document doc = Jsoup.parse(html);

        Elements directors = doc.select("span.role[title='导演 Director']");
        for (Element director : directors) {
            System.out.println(director.parent().select("a.name").text());
        }
    }
}

输出结果：

郭帆 Frant Gwo
