解析JSOUP表

Question

我想解析一个HTML表，但我不明白如何获得值。我有这张桌子：

<table class="aircraftInfoGrid">
            <tbody>
              <tr class="first">
                <td class="iconContainer">
                  <span class="icon aircraft"></span>
                </td>
                <td colspan="2">
                  Aircraft<span class="right" id="aircraftIcaoVal">(A320)</span><br>
                  <span id="aircraftVal" class="strong">Airbus A320-214</span>
                </td>
              </tr>
              <tr>
                <td class="iconContainer"></td>
                <td colspan="2">
                  Registration<span class="right" id="hexVal">(4CA212)</span><br>
                  <span id="registrationVal" class="strong"><a class="regLink" data-reg="EIDEB">EI-DEB</a></span>
                </td>
              </tr>
              <tr>
                <td class="iconContainer">
                  <span class="icon cloud"></span>
                </td>
                <td>
                  Altitude<br>
                  <span id="altitudeVal" class="strong hasTooltip" data-tooltip-align="left" data-tooltip-value="2,438 m">8,000 ft</span>
                </td>

                </td>
              </tr>
              <tr>
                <td class="iconContainer"></td>
                <td>
                  Speed<br>
                  <span id="speedVal" class="strong hasTooltip" data-tooltip-align="left" data-tooltip-value="469 km/h, 291 mph">253 kt</span>
                </td>
                <td>

                </td>
              </tr>
              <tr>
                <td class="iconContainer">
                  <span class="icon satellite"></span>
                </td>
                <td>

                </td>
              </tr>
              <tr>
                <td class="iconContainer"></td>

              </tr>
            </tbody>
          </table>

doc = Jsoup.connect("http://x.com/EIN1C6/367d800").timeout(10*1000).get();
org.jsoup.nodes.Element tabella = doc.getElementsByClass("aircraftInfoGrid").first();

Iterator<org.jsoup.nodes.Element> iterator = tabella.select("td").iterator();
while(iterator.hasNext()){   
    iterator.next().text();
    System.out.println("TITLE: "+iterator.next().text());
}

你能为我杀一儆百吗？我要分析此表得所有值...提前谢谢！

编辑：SPAN值：

    05-24 11:08:49.240: I/System.out(3679): TD Value : Aircraft
05-24 11:08:49.240: I/System.out(3679): TD colspan : 2
05-24 11:08:49.240: I/System.out(3679):     SPAN Value : 
05-24 11:08:49.240: I/System.out(3679):     SPAN class : right
05-24 11:08:49.240: I/System.out(3679):     SPAN id : aircraftIcaoVal
05-24 11:08:49.240: I/System.out(3679):     SPAN Value : 
05-24 11:08:49.240: I/System.out(3679):     SPAN id : aircraftVal
05-24 11:08:49.240: I/System.out(3679):     SPAN class : strong

Answer 1

如果想要span详细信息，只需嵌套for循环即可。例如，下面的程序打印出此表的所有值。我只是将gien html复制到一个文件中，这样程序就可以从一个文件中读取。你可以把它改成你的URL。

import java.io.File;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Attribute;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;


public class JsoupParser {

    public static void main(String[] args) throws Exception {
        File input = new File("t.html");

        Document doc = Jsoup.parse(input, "UTF-8");

        int index = 0;
        for (Element td : doc.select("td")) {
            System.out.println("************************************");
            System.out.println("Row " + (++index));
            System.out.println("************************************");
            printValuesAndAttributes("TD", td);
            for(Element span : td.select("span")){
                printValuesAndAttributes("\tSPAN", span);
            }
        }
    }

    private static void printValuesAndAttributes(String prefix, Element el) {
        System.out.println(prefix +" Value : " + el.text());
        for(Attribute attr : el.attributes()){
            System.out.println(prefix + " " + attr.getKey() + " : " + attr.getValue());
        }
    }

}

如果您想要整个span标记html，请使用toString方法；如果您想要该值，请像上面一样使用el.text（）

for (Element span : doc.select("td span")) {
    System.out.println(span);
}
