我用这个code，它解析整个细节，而不是解析'播种机'和; leechers
{尝试
文件= Jsoup.connect（BLOG_URL）获得（）;
标题= document.title时（）;
}赶上（IOException异常五）{
// TODO自动生成catch块
e.printStackTrace（）;
}
//选择查询
元素nodeBlogStats = document.select（＃DIV范围）;
//检查结果
如果（nodeBlogStats.size（）大于0）{
//获得价值
结果= nodeBlogStats.get（0）的.text（）;
}
解决方案
根据 http://jsoup.org/apidocs/org/jsoup/select/Selector.html ，您正在寻找
电子〜F 的F元素$ P $由同级Ëpceded
和
：包含（文本）元素包含指定文本
我会尝试
元素播种机= document.select（DT：包含（播种机）〜DD）得到（0）;
元素leechers = document.select（DT：包含（Leechers）〜DD）得到（0）;I want to parse

try { document = Jsoup.connect(BLOG_URL).get(); title = document.title(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } // selector query Elements nodeBlogStats = document.select("div#details"); // check results if (nodeBlogStats.size() > 0) { // get value result = nodeBlogStats.get(0).text(); }
解决方案According to http://jsoup.org/apidocs/org/jsoup/select/Selector.html, you are looking for
E ~ F an F element preceded by sibling E
and
:contains(text) elements that contains the specified text.
I would try
Element seeders = document.select("dt:contains(Seeders) ~ dd").get(0); Element leechers = document.select("dt:contains(Leechers) ~ dd").get(0);
