JSOUP选择具有特定ID的<div>

Question

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:

EDIT: 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">

        <h2><span id="lblEventName">American Cancer Society 44th Annual Walter Hagen Golf Tournament</span></h2>
        <!-- General Information Box -->

</div> <!-- end standard display -->

EDIT: 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?

The code where I'm using the select() is shown below. As I said before, I tried to use

select("div[id=pnlResults]);

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;
}

Any help would be greatly appreciated.

Answer 1

Try:

 Elements info = eventInfo.select("div#pnlResults");

Update for your update:

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.

Answer 2

If you want to get content of the div with id "pnlResults", JSoup provide method .

For example, if you want get that content and put it in string, you can do it like this:

Document document = Jsoup.connect(LINK_TO_WEBSITE).get();
String content = document.getElementById("pnlResults").outerHtml();

Then, you can put this content in Android's WebView, and it will work nice.

Hope this will help someone!

Answer 3

This worked for me:

import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;

public class DivStuff {
   public static final String MY_PAGE = "http://www.cancer.org/Involved/Participate/app" +
        "/event-search.aspx?zip=28590&city=&state=&local-radius=20&textsrch=&startdate=" +
        "11%2F13%2F2011&enddate=&all=1";
   private static final String[] HEADINGS = {"Event", "Location", "City, State", "Date", "Distance"};
   private String page;


   public static void main(String[] args) throws IOException {
      Document doc = Jsoup.connect(MY_PAGE).get();

      Elements links = doc.select("table");
      Elements links2 = links.select("tr");

      if (links2.size() < 2) {
         return;
      }

      for (int i = 1; i < links2.size(); i++) {
         Elements innerDetails = links2.get(i).select("td");
         if (innerDetails.size() != 5) {
            break;
         }
         for (int j = 0; j < HEADINGS.length; j++) {
            System.out.print(HEADINGS[j] + ": ");
            if (j == 0) {
               System.out.println(innerDetails.get(j).select("a").get(0).text());
            } else {
               System.out.println(innerDetails.get(j).text());
            }
         }
         System.out.println();
      }
   }
}
