Python美化组以获取数据<span>标记

Question

我正在尝试获取标签数据

html示例：

<span class=\"value\">3.99<\/span> average rating,\n

这是我的代码：

d = BeautifulSoup(fstuff.text, 'html.parser')
d.select_one("span.average").text

但我有一个错误：

--------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-60-b6b8329a8fe3> in <module>()
----> 1 d.select_one("span.average").text
AttributeError: 'NoneType' object has no attribute 'text'

请帮帮我！ 谢谢

Answer 1

如果您想获得值3.99，只需使用

print(soup.select_one('span.value').text)

如果要获取average rating,，请使用next_sibling

print(soup.select_one('span.value').next_sibling.strip())

代码：

from bs4 import BeautifulSoup
html='''<span class=\"value\">3.99</span> average rating,\n'''
soup=BeautifulSoup(html,'html.parser')
print(soup.select_one('span.value').text)
print(soup.select_one('span.value').next_sibling.strip())
