好的，这里有四张桌子。我想要实现的是只选择其前面的元素是 h3 并且 h3 包含“Tier”或“Games”的表格。

我完全无法理解这一点。我提出了 2 个选项（我一直虔诚地重复一个选项，就像我要强迫它给我所需的结果或其他东西一样）。第一个是：

//h3[contains (., 'Tier') or (., 'Games')]/following::table/tbody/tr/td[1]

这对我来说似乎很简单，但它没有得到所需的结果。另一个是：

//table[preceding-sibling::h3[contains(., 'Tier') or (., 'Games')]]/tbody/tr/td[1]

这个更有意义，但还是没有得到所需的结果。

你已经接受的答案，他没有在他的 xpath 中使用or 运算符，这对于这张特殊的票来说是至关重要的。您从哪里得到 xpath 中的 or 运算符的引用？ @PavleĆurčić。您几乎没有任何功劳就使用我的解决方案。

【解决方案1】：

这有点棘手，但找到了解决方案。如果您在下面看到，所有table 和h3 标签都是兄弟。在您的xPath 中，您使用的是table/tbody/tr/td[1]，但未指定您指的是哪个表。

我使用表索引来获取特定表的元素。赞following-sibling::table[1]

Tier1 表的 xPath：仅返回 Tier1 表的 td 标记。

//strong[contains(text(),'Tier 1 - 1 USD')]//parent::h3//following-sibling::table[1]//tbody//tr//td

Tier2 表的xPath：仅返回Tier2 表的td 标记。

//strong[contains(text(),'Tier 2 - BTA')]//parent::h3//following-sibling::table[1]//tbody//tr//td

Tier3 表的xPath：仅返回Tier3 表的td 标记。

//strong[contains(text(),'Tier 3 - 12 USD')]//parent::h3//following-sibling::table[1]//tbody//tr//td

所有表格的动态 xPath：

//strong[contains(text(),' + tableName + ')]//parent::h3//following-sibling::table[1]//tbody//tr//td

【讨论】：

我真的很喜欢 table 元素上的索引。我最终使用的是： //h3[contains(., 'Tier') or contains(., 'Games')]/following-sibling::table[1]/tbody/tr/td[1] 不管怎样，谢谢！

【解决方案2】：

您分享了 4 个h3 tags。

3 其中包含层（不是直接，但他们的孩子包含那些文本）。所以你可以使用下面的 xapth ：

//strong[contains(text(),'Tier') or contains(text(), 'Games')]/parent::h3

我看到你对tr/td[1]元素感兴趣，如果有，请使用

//strong[contains(text(),'Tier') or contains(text(), 'Games')]/parent::h3/following-sibling::table/descendant::tr/td[1]
