问题描述
我在做一个小的Android应用程序的一类，我觉得从美国癌症协会的网站上癌症相关的事件。我一直在使用JSoup已经获得有关事件的基本信息，并得到我试图使用select（）方法，该网站的具体信息。但是，我使用的是待价而沽的方式更多的HTML节点比我想，我无法弄清楚，为什么当前的方法。我试图抓住该表看起来是这样的：
I'm making a small Android application for a class where I find cancer-related events from the American Cancer Society's website. I've been using JSoup to get basic information about the events, and to get specific information from the website I've tried to use the select() method. However, the current method that I'm using grabs way more HTML nodes than I would like and I couldn't figure out why. The table that I'm trying to grab looks like this:
编辑：我意识到其中id =pnlResults并没有结束，在该表中，约3个表后结束，所有的，我想抓住信息。下面是该表再次
I realized that the where id = "pnlResults" does not end at that table, it ends after about 3 more tables, all with information that I would like to grab. Here is the table again
<div id="pnlResults">

编辑：鉴于这些新表，我想提取的一般信息，以及活动地点。我怎么会去这样做？也许使用的选择子集我只能再次选择当标头是我想要什么？
Given these new tables, I would like to extract the General Information, and Event location. How would I go about doing that? Maybe using the subset of select I just got to select again Where the headers are what I want?
在code，其中我使用select（），如下图所示。正如我之前所说，我试图用
The code where I'm using the select() is shown below. As I said before, I tried to use
select("div[id=pnlResults]);
但返回的数据不仅仅是股利其中ID为pnlResults得多。
but the returned data is much more than just the div where the id is pnlResults.
public ArrayList<Event> results()
{
ArrayList<Event> results = new ArrayList<Event>();
Document doc = Jsoup.parse(page);
Elements links = doc.select("a[href*=event-details]");
for(Element e: links)
{
String title = e.text();
String link = "http://www.cancer.org/involved/participate/app/"+e.attr("href");
try{
Document eventInfo = Jsoup.connect(link).get();
Elements info = eventInfo.select("div[id*=pnlResults");
}
catch(MalformedURLException exception)
{
exception.printStackTrace();
}
catch(IOException exception)
{
exception.printStackTrace();
}
}
return results;
}
任何帮助将是很大的AP preciated。
Any help would be greatly appreciated.
推荐答案
尝试：
Elements info = eventInfo.select("div#pnlResults");
更新您的更新：
既然你现在有更多的数据，而且由于HTML本身不是很大，你就只需要工作，通过它来挑选出你的数据。如果你需要的所有内容都 ID 值，然后使用 ID 这些元素的属性来获取文本。
Since you now have more data, and since the HTML itself isn't that great you'll just have to work through it to pick out your data. If the content you need all have id values then use the id attribute of those elements to get the text.
