XPath:在某个标记之后和相同的下一个标记之前选择文本

Question

我有这样的HTML代码:

<strong>Term:</strong>
Some text<br />
More text<br />
Some more lines of text
<strong>Term:</strong>
Some text<br />
More text<br />
Some more lines of text
<strong>Second term:</strong>
Some text<br />
More text<br />
Some more lines of text
<strong>Term:</strong>
Some text<br />
More text<br />
Some more lines of text

我需要在标签与文本"Term"之间和下一个标签之前获取文本节点:

Some text
More text
Some more lines of text
Some text
More text
Some more lines of text
Some text
More text
Some more lines of text

这里可以使用条件:previous标签必须包含文本"Term",但我不知道如何创建这样的xpath选择器.

Answer 1

//text()[preceding::*[contains(text(),'Term:')] and following::*[contains(text(),'Term:')]]

它与empo建议的相同.但是,我正在寻找一个包含Term的节点,并返回它们之间存在的所有文本节点.

但是,只有当您没有任何其他"术语"时,这才能正常工作.如果是这种情况,请告诉我,因为这个Xpath也将返回一些不需要的值.

从现在开始,您已更新输入.我只是在上一个Xpath中添加了一个条件.

//text()[preceding::*[contains(text(),'Term:')] and following::*[contains(text(),'Term:')] and not(contains(., 'Term:'))]

@empo解决方案也有效.但我们考虑<strong>到了这一点.我编写的xpath只检查单词'Term:'并给出它们之间的所有textNodes.

如果这对您有用,请告诉我.

问候.

Answer 2

您的问题仍然不明确，您的输入文档格式不正确。检查一下：

root/text()[preceding::strong[1][contains(text(),'Term')]]

应用于：

<root>
<strong>Term:</strong>
Some text<br />
More text<br />
Some more lines of text
<strong>Term:</strong>
Some text2<br />
More text2<br />
Some more lines of text2
<strong>Second term:</strong>
Some text3<br />
More text3<br />
Some more lines of text3
<strong>Term:</strong>
Some text4<br />
More text4<br />
Some more lines of text4
</root>

产生：

Some text
More text
Some more lines of text

Some text2
More text2
Some more lines of text2

Some text4
More text4
Some more lines of text4

此 XPath 选择包含字符串的元素Term:和包含任何字符串的元素之间的所有文本节点：

//text()[preceding::*[contains(text(),'Term:')] and following::*[text()]]

应用于：

<root>
<strong>Term:</strong>
Some text<br />
More text<br />
Some more lines of text
<strong>Second term:</strong>
Some text2<br />
More text2<br />
Some more lines of text2
</root>

返回：

Some text
More text
Some more lines of text
