我的html页面中有下面的代码。
<tr id="HL1035569648A" bgcolor="#ffffff">
<td rowspan="2" align="center" width="40"><input name="product_id" value="1035569648" onclick="syncSA(this,document.inquiry.toggleSA);hlChecked(this,document.inquiry.product_id,2,'#ffffff');" type="checkbox"></td>

</td>
</tr>`我要检索链接和描述
<td><a href="http://www.globalsources.com/gsol/I/Induction-cooker/p/sm/1035569648.htm" name="1035569648">Induction <b>Cooker</b></a><br>
Induction Cooker with 50/60Hz Rated Frequency, 90 to 230V AC Input Voltages and 7.2kW Maximum Power<br></td>`我正在使用下面的XPath：
//Link: http://www.globalsources.com/gsol/I/Induction-cooker/p/sm/1035569648.htm
driver.findElements(By.xpath("//tr[starts-with(@id, 'HL')]/td[3]/a");
//Summary: Induction Cooker with 50/60Hz Rated Frequency, 90 to 230V AC Input Voltages and 7.2kW Maximum Power
driver.findElements(By.xpath("//tr[starts-with(@id, 'HL')]/td[3]");注意:我不能使用HL1035569648A id ，因为有许多表行具有这个链接，而且所有表行都有不同的类名，但它们都以HL.开头。
这在FirefoxDriver中很好，但不适用于HtmlUnitDriver。任何人都能帮我。我不明白这个问题。
谢谢!

不惜一切代价避免XPATH定位器！
您可以很好地使用css : trid^='hl‘td:eq(2) a
但是，希望您不需要这个中间位，只需做一些类似trid^='hl‘a之类的事情。
