我正在尝试从该网站获取一些信息:
表结构为:
<td headers="header2">
Take the Eastern Suburbs and Illawarra train (CityRail)
<br />
<b>Dep: 12:35pm Hurstville Station Platform 3</b>
<br />
<b>Arr: 1:06pm Town Hall Station Platform 5, Sydney</b>
<br />
</td>
我的代码:
import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;
import android.app.Activity;
import android.os.Bundle;
public class JsouptestActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
jsouptest();
}
public void jsouptest() {
Document doc = null;
try {
doc = Jsoup
.connect(
"http://www.131500.com.au/plan-your-trip/trip-planner?itd_name_origin=hurstville&itd_name_destination=town+hall")
.get();
} catch (IOException e) {
Elements tables = doc.select("div#boxbody");
System.out.println(tables.get(0).text().toString());
}
}
}
我期望看到的:
Take the Eastern Suburbs and Illawarra train (CityRail)
Dep: 12:35pm ; Hurstville Station Platform 3
Arr: 1:06pm ; Town Hall Station Platform 5, Sydney
我试过的:
Elements tables = doc.select("div#boxbody table#dataTbl");
Elements tables = doc.select("div#boxbody table#dataTbl+widthcol2and3");
因为数据实际上在
<table class="dataTbl widthcol2and3" cellspacing="0" style="margin:0px ! important;border-right:0px none;" summary="Search Results Details">
所以我想我不能只使用这个(dataTbl 和 widthcol2and3 之间的空格):
Elements tables = doc.select("div#boxbody table#dataTbl widthcol2and3");
所以我尝试了:
Elements tables = doc.select("div#boxbody iewfix"); // and div#boxbody+iewfix
但是每次我尝试在模拟器中运行测试应用程序时,我得到了
The application has stopped unexpectedly. Please try again.

jsoup 似乎找不到合适的课程。
我认为我的 selector-syntax 是错误的,但是我查看了Use selector-syntax to find elements,我仍然无法解决这个问题。
请在这个问题上帮助我。
