使用Jsoup提取文本 [英] Extracting text with Jsoup

问题描述

我正试图从以下页面获取信息: http://fantasynews.cbssports.com/fantasyfootball/players/updates/187741

I am trying to get information from the following page: http://fantasynews.cbssports.com/fantasyfootball/players/updates/187741

我需要为每个项目获取单独的字符串:

I need to get separate strings for each of these items:

1. 新闻标题
2. 新闻
3. 分析

现在，我可以使用以下方法从整个表格中获取信息:

Right now I am able to get information from the whole table using:

 doc = Jsoup.connect("http://fantasynews.cbssports.com/fantasyfootball/players/updates/" + playerId).timeout(30000).get();
 Element title = doc.select("[id*=newsPage1]").first(); 

但这是所有文章一起运行的结果.

But the result of this is all of the articles run together.

有人可以建议吗?

谢谢乔什

推荐答案

您需要使用更复杂的CSS选择器.也许像这样:

You need to use more elaborate css selectors. Maybe something like:

public static void main(String[] args) {
  Pattern pat = Pattern.compile("(.*)News\\:\\p{Zs}(.*)Analysis\\:\\p{Zs}(.*)", Pattern.UNICODE_CASE);
  Document doc = null;
  try {
    doc = Jsoup.connect("http://fantasynews.cbssports.com/fantasyfootball/players/updates/187741").userAgent("Mozilla").get();
  } catch (IOException e1) {
    e1.printStackTrace();
    System.exit(0);
  };

  Elements titles = doc.select("table h3");
  for (Element title : titles){
    Element td = title.parent();
    String innerTxt = td.text();
    Matcher mat = pat.matcher(innerTxt);
    if (mat.find()){
      System.out.println("titel = " + mat.group(1));
      System.out.println("news = " + mat.group(2));
      System.out.println("analysis = " + mat.group(3));
    }
  } 
}

我建议您研究CSS选择器和 JSoup文档.

I suggest you look into css selectors and the JSoup documentation.
