从 lxml 获取内部文本

Question

lxml.html.fromstring 坚持将所有内容包装在标签中（p 默认值）。从这个标签树中，

<p>this is <b>the</b> good stuff<p>

我要提取字符串：

this is <b>the</b> good stuff

我该怎么做？

Answer 1

这通常被称为 "inner xml" 而不是 "inner text"。这是获取元素内部 xml 的一种可能方法：

import lxml.etree as etree
import lxml.html

html = "<p>this is <b>the</b> good stuff<p>"
tree = lxml.html.fromstring(html)
node = tree.xpath("//p")[0]

result = node.text + ''.join(etree.tostring(e) for e in node)
print(result)

输出：

this is <b>the</b> good stuff
