英文:
How works following-sibling with elements like strong?
问题
I'm here to assist with the Chinese translation. Here is the translated content:
在URL上，我正在尝试使用XPath获取特定HTML元素的内容，就像屏幕截图中的内容：
我尝试了多个XPath和设置，如下所示：
//td[contains(@class, "productTitle")]/strong[contains(text(),"Movement:")]/following-sibling::td
//td[@class="productTitle"]/strong[text()="Movement:"]/following-sibling::td
但都没有对我起作用。
只有//td[contains(@class, "productTitle")]/following-sibling::td部分地对我起作用（获取所有元素，而不是我正在寻找的单个元素），而且它不符合我的需求，因为我需要与<strong>元素的内容相关，以获取列标题。
英文:
On the URL I’m trying to get with XPath the content of certain HTML element, like on the screenshot:
I tried it with multiple XPaths and settings, like
//td[contains(@class, "productTitle")]/strong[contains(text(),"Movement:")]/following-sibling::td
//td[@class="productTitle"]/strong[text()="Movement:"]/following-sibling::td
But nothing worked for me.
Only the variant //td[contains(@class, "productTitle")]/following-sibling::td worked partly for me (getting all elements, and not the single one I'm looking for), and it doesn’t match my need, because I need the relation on the content of the <strong>-element, to get the column heading.

当上下文为 strong 时，没有下一个兄弟节点 td，所以你需要返回到父级。
示例（未经测试）...
//td[contains(@class, "productTitle")]/strong[contains(text(),"Movement:")]/../following-sibling::td
然而，我更倾向于基于第一个 td 选择正确的 tr，然后选择第二个 tr（同样未经测试）...
//tr[td[1][contains(@class,'productTitle')][contains(.,'Movement:')]]/td[2]
英文:
There is no following-sibling td when the context is strong, so you'd have to go back up to the parent.
Example (untested)...
//td[contains(@class, "productTitle")]/strong[contains(text(),"Movement:")]/../following-sibling::td
However, I would prefer selecting the correct tr based on the first td and then selecting the second tr (also untested)...
//tr[td[1][contains(@class,'productTitle')][contains(.,'Movement:')]]/td[2]
