使用 selenium 我试图读出一个动态生成的表,我找到了正确的元素(使用该findElement
方法),但getText()
在它们上使用什么也不返回。
可能是因为在返回“文本”时查找引号并且在标签getText()
之间找不到任何引号。<td>
一些建议是使用 xpaths,但由于表是动态生成的,所以我需要的值的位置也会发生变化。
这是我试图从中获取 3 个数据点的表:
<table cellpadding="0" cellspacing="0" class="fleetinfo">
<tbody><tr>
<th colspan="2">Schepen:</th>
</tr>
<tr>
<td>Groot vrachtschip:</td>
<td class="value">
40 </td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
<tr>
<th colspan="2">Lading:</th>
</tr>
<tr>
<td>Metaal:</td>
<td class="value">
536.062 </td>
</tr>
<tr>
<td>Kristal:</td>
<td class="value">
289.008 </td>
</tr>
<tr>
<td>Deuterium:</td>
<td class="value">
92.750 </td>
</tr>
</tbody></table>
我感兴趣的是<td class="value">
标签内的那些,但正如我之前所说,getText()
在它们上使用会返回 null。
关于如何获取这些值的任何想法?
编辑:这就是我现在的做法
private int getMetalFromFleet(WebElement fleet)
{
int ret=0;
WebElement streak = fleet.findElement(By.className("starStreak"));
List<WebElement>fleetDetails = streak.findElements(By.tagName("tr"));
for(WebElement detail : fleetDetails)
{
List<WebElement> tabel = detail.findElements(By.tagName("td"));
if(tabel.size() != 2)
continue;
if(tabel.get(0).getText().equalsIgnoreCase("metaal:"))
{
ret = Integer.parseInt(tabel.get(1).getText());
break;
}
}
return ret;
}
编辑:这是html的相关位

我需要的值是“金属”、“水晶”和“氘”下的数值。
