从lxml获取内部文本

问题描述

lxml.html.fromstring坚持将所有内容包装在标记中(默认为p).在此标签树中，

lxml.html.fromstring insists on wrapping up everything in a tag (p default). From this tag tree,

<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?

推荐答案

通常称为内部xml"，而不是内部文本".这是获取元素内部xml的一种可能方法:

That's often referred to as "inner xml" rather than "inner text". This is one possible way to get inner xml of an element :

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
