I want to retrieve link and description

<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>`

I am using below 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]");

Note: I cannot use HL1035569648A full id because there are many Table Rows having this links and all table rows has different class name but they all starts with HL.

This works fine with FirefoxDriver but it is not working with HtmlUnitDriver. Is anyone can help me. I am not understanding the issue.

thanks!

Avoid XPATH locators at all costs!

You can use css just fine: tr[id^='hl'] td:eq(2) a

However hopefully you don't need that middle bit and can just do something like tr[id^='hl'] a

Try this:
