我问了一个关于在 xpath 中遍历回父节点的问题
我得到了预期的答复，但是我对进一步的发展还有一个疑问。使用以下 HTML：

在现在的帮助下，@Alex我可以获得所有部分和小节。然后我想要小节内的文章，我自己尝试并收到了预期的输出，但是我的问题现在是在<li class="subsection">标签之后我们有单独<li class="circle">的标签，其中包含标签内文章的信息anchor，现在因为class="circle"标签本身就是单独的节点（不在class="subsection"节点内），我不能只在特定小节内获取文章，它会获取第一小节中的所有文章，然后在第二小节中它还从第三小节中获取文章，它只能在最后一个小节，因为它没有更多的小节。
谁能告诉我如何限制特定子部分中的文章，我的意思是当它获得class="subsection"标签时，它应该停止为该子部分进一步获取文章，并开始为另一个子部分获取文章。
