您可以将选择器简化为P:contains（Previous chapple)A，它查找包含文本“Previous chapple”的P标记内的A标记。

完整示例：

String url = "http://www.mangahere.com/manga/mirai_nikki/v07/c032/";
String ua = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.33 (KHTML, like Gecko) Chrome/27.0.1438.7 Safari/537.33";

Document doc = Jsoup.connect(url).userAgent(ua).timeout(10 * 1000).get();
Element a = doc.select("p:contains(Previous Chapter) a").first();
String backUrl = a.attr("href");

System.out.println(String.format("Back URL: %s (%s)", backUrl, a.text()));
