python - lxml findall div 和 span 标签

Question

如何找到所有 div 和 span 标签并保留订单。使用 BeautifulSoup 非常简单：soup.findAll(name=['span', 'div'])，但我最近切换到 lxml，因为它比 BeautifulSoup 快得多。

Answer 1

import lxml.html
from lxml.cssselect import CSSSelector
content = result.read()
page_html = lxml.html.fromstring(content)

elements = page_html.xpath('//*[self::div or self::span]')

或者

sd_selector = CSSSelector('span,div')
elements = sd_selector(page_html)

Answer 2

import lxml.html as LH
content = '''\
<tr>
<div>idend</div>
<span>Green<\span>
<tr>
'''
root = LH.fromstring(content)
for tag in root.xpath('//*[self::div or self::span]'):
    print(tag)
