CSS选择器只选择第一行

Question

我解析一个html页面，并有一个长的CSS选择器（我找不到一个较短的，因为该页面是愚蠢的）。它应该选择表中的所有tr，但只选择第二行......我错过了什么？

的选择：

body > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(2) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(3) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(8) > td:nth-child(1) > table:nth-child(4) > tbody:nth-child(1) > tr:nth-child(2) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) tr:not(:first-child) 

页有对方内线多个表，但前90％甚至没有事，选择我要使用该表后，我跟随了一个“[space]tr:not(...) “，所以它应该选择所有的降行，不是吗？

后，年龄看起来是这样的：

Answer 1

body > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(2) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(3) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(8) > td:nth-child(1) > table:nth-child(4) > tbody:nth-child(1) > tr:nth-child(2) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) tr:not(:first-child)

不完全回答你的问题，但如果将M arkup不解析友好，我需要找到一个深深嵌套在可怕的标记table元素中，我更喜欢通过找到它存在的特定标题。在这种情况下，您可以找到具有Part Number标题的表格。实例的XPath：

//table[tr[1]/td/b = "Part Number"] 

接着，在该表中，可以使用"not first child" CSS选择器：

tr:not(:first-child) 

或者，您也可以使用adjacent selector（找到tr元素之后tr元素，这在逻辑上排除第一行）：

tr + tr 

希望这会简化一些事情。
