try using css selectors alternative: 尝试使用CSS选择器替代方法：
String cssSelector="td[class='icon-button combo-button']>img"
driver.findElement(By.cssSelector(cssSelector)).click();
a piece of advice: use firebug, firefox extension to verify you located element properly 一条建议：使用firebug，firefox扩展程序来验证您正确定位了元素

Just as a different solution to eugene (which, by the way, is a better way of doing it since the CSS selector will be faster), if you must use XPath: 正如必须使用XPath的另一种方法来解决eugene（顺便说一句，这样做是一种更好的方法，因为CSS选择器会更快）：
//td[@class='icon-button combo-button']/img
Your original XPath solutions will never work, they are very confined to specific positions. 您原始的XPath解决方案将永远无法使用，它们只能在特定位置使用。 You put in an extra div somewhere and your entire XPath will fall over. 您在某个地方放了一个div，整个XPath就会崩溃。 So go for something that's a little less brittle. 因此，选择一些不那么脆弱的东西。
