</tbody></table>

我尝试过没有成功：以下是我尝试过的一个。

    //*[@id="trades"]/tbody/tr/td[1]/table/tbody/tr[5]/td[2]

    //*[@id="trades"]/tr/td[1]/table/tbody/tr[5]/td[2]

和许多其他..;-）

Answer 1

我必须删除两个“ tbody”

// * [@ id ='trades'] / tr / td / table / tr [4] / td [2]

Answer 2

此XPath，

substring-before(//table[@id="trades"]
                 //td[.="Average Win:"]/following-sibling::td[1], " /")

将选择

36.68 pips

根据要求，您会发现它比许多替代产品都更坚固。例如，表结构可能会发生重大变化，只要两个表单元的标签和相对位置保持不变，该XPath就会继续起作用。

基于标签的表单元格（td）内容的XPath？
