我是android编程的初学者。我正在开发一个使用jsoup解析来自网站的HTML表数据的应用程序。我面临的问题是,表没有id,所有表数据都相同class name。我如何从单个列中选择数据?我只想要第二列的表数据
这是HTML:
<table width=100% border=0 cellpadding=1 cellspacing=1>
<tr class="rowdeep">
<td align="center" class="bodytext"><strong>Train No</strong></td>
<td align="center" class="bodytext"><strong>Name</strong></td>
<td align="center" class="bodytext"><strong>Off Day</strong></td>
<td align="center" class="bodytext"><strong>From</strong></td>
<td align="center" class="bodytext"><strong>Departure</strong></td>
<td align="center" class="bodytext"><strong>To</strong></td>
<td align="center" class="bodytext"><strong>Arrival</strong></td>
</tr>
<tr class="rowlight">
<td align="center" class="bodytext">773</td>
<td align="center" class="bodytext">Kalani Express</td>
<td align="center" class="bodytext">Friday</td>
<td align="center" class="bodytext">Dhaka</td>
<td align="center" class="bodytext">4:00:00 PM</td>
<td align="center" class="bodytext">Sylhet</td>
<td align="center" class="bodytext">10:45:00 PM</td>
</tr>
<tr class="rowlight">
<td align="center" class="bodytext">707</td>
<td align="center" class="bodytext">Tista Express</td>
<td align="center" class="bodytext">Monday</td>
<td align="center" class="bodytext">Dhaka</td>
<td align="center" class="bodytext">7:20:00 AM</td>
<td align="center" class="bodytext">Dewangonge Bazar</td>
<td align="center" class="bodytext">12:55:00 PM</td>
</tr>
<table>
答案 0 :(得分:1)
因此,假设您已经将HTML解析为文档,这应该可行:
Elements tableRows = doc.select("tr.rowdeep, tr.rowlight");
for (Element e : tableRows) {
System.out.println(e.child(1).text()); // index of 2nd column
}
将输出:
Name
Kalani Express
Tista Express
