'NoneType'对象没有属性'text'

Question

如何在dd中提取“£70,004”文本，省略dt中的“投资寻求”文本。

from bs4 import BeautifulSoup
import urllib2

url="https://www.seedrs.com/tanorganic"
page = urllib2.urlopen(url)
soup = BeautifulSoup(page.read(), "html.parser")

target = soup.find("dl", class_="investment_sought").text

print target

figure = soup.find("dd", class_="investment_sought").text

print figure

结果：

Investment

sought:

£70,004

Traceback (most recent call last):
  File "testing.py", line 12, in <module>
    figure = soup.find("dd", class_="investment_sought").text
AttributeError: 'NoneType' object has no attribute 'text'

Answer 1

我建议您更改最后4行，如下所示，因为没有dd标记investment_sought作为类属性值。如果您不想要删除第一个print stmt ..

target = soup.find("dl", class_="investment_sought")
print target.text
figure = target.find("dd").text
print figure

示例：的

>>> from bs4 import BeautifulSoup
>>> import urllib2
>>> url="https://www.seedrs.com/tanorganic"
>>> page = urllib2.urlopen(url)
>>> soup = BeautifulSoup(page.read(), "html.parser")
>>> target = soup.find("dl", class_="investment_sought")
>>> print target.text


Investment

sought:

£70,004

>>> figure = target.find("dd").text
>>> print figure
£70,004
>>>
