我想解析一个HTML表，但我不明白如何获取值。 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>
Vertical Speed<br>
<span id="vspdVal" class="strong">0 fpm</span>
</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>
Track<br>
<span id="trackVal" class="strong">267°</span>
</td>
</tr>
<tr>
<td class="iconContainer">
<span class="icon satellite"></span>
</td>
<td>
Latitude<br>
<span id="latVal" class="strong">51.593</span>
</td>
<td>
Longitude<br>
<span id="lonVal" class="strong">-0.5887</span>
</td>
</tr>
<tr>
<td class="iconContainer"></td>
<td>
Radar<br>
<span id="radarVal" class="strong">N-EGLM2</span>
</td>
<td>
Squawk<br>
<span id="squawkVal" class="strong">7651</span>
</td>
</tr>
</tbody>
</table>
我不明白它是如何解析的：这是我的代码：
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());
}
我得到了这个输出：
05-24 07:03:18.270: I/System.out(2088): TITLE: Aircraft
05-24 07:03:18.270: I/System.out(2088): TITLE: Registration
05-24 07:03:18.280: I/System.out(2088): TITLE: Altitude
05-24 07:03:18.290: I/System.out(2088): TITLE:
05-24 07:03:18.290: I/System.out(2088): TITLE: Track
05-24 07:03:18.310: I/System.out(2088): TITLE: Latitude
05-24 07:03:18.310: I/System.out(2088): TITLE:
05-24 07:03:18.320: I/System.out(2088): TITLE: Squawk
编辑：SPAN VALUE：
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

如果你想要跨度细节，只需嵌套for循环。例如，以下程序打印出该表的所有值。我只是将gien html复制到一个文件中，以便程序从文件中读取。您可以将其更改为您的网址。
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());
}
}
}
如果你想要整个span标签html然后使用toString方法，或者如果你想使用像上面那样的值作为el.text（）
for (Element span : doc.select("td span")) {
System.out.println(span);
}

我这样做
Document doc1;
doc1 = Jsoup.connect("http://localhost:8080/WebApplication1/").get();
String title = doc1.title();
//int i = 0;
//System.out.println("title is: " + title);
//System.out.println("AAA");
Elements tr = doc1.select("tr");
//Elements td = doc1.select("td");
//System.out.println(td.size());
for (int i = 0; i < tr.size(); i++) {
if (!(tr.get(i).child(1).text().contains("Court NOT in session!"))) {
System.out.println("Court Number"+tr.get(i).child(0).text());
System.out.println("Sl Number"+tr.get(i).child(1).text());
System.out.println("List Type "+tr.get(i).child(2).text());
}
//System.out.println(i);
}
