在标签 BeautifulSoup 内显示文本 [英] Show text inside the tags BeautifulSoup

问题描述

我试图只显示标签内的文本，例如:

I'm trying to show only the text inside the tag, for example:

<span class="listing-row__price ">$71,996</span>

我只想展示

$71,996"

我的代码是:

import requests
from bs4 import BeautifulSoup
from csv import writer

response = requests.get('https://www.cars.com/for-sale/searchresults.action/?mdId=21811&mkId=20024&page=1&perPage=100&rd=99999&searchSource=PAGINATION&showMore=false&sort=relevance&stkTypId=28880&zc=11209')

soup = BeautifulSoup(response.text, 'html.parser')

cars = soup.find_all('span', attrs={'class': 'listing-row__price'})
print(cars)

如何从标签中提取文本?

How can I extract the text from the tags?

推荐答案

要获取标签内的文本，有几种方法，

To get the text within the tags, there are a couple of approaches,

a) 使用标签的 .text 属性.

a) Use the .text attribute of the tag.

cars = soup.find_all('span', attrs={'class': 'listing-row__price'})
for tag in cars:
    print(tag.text.strip())

输出

$71,996
$75,831
$71,412
$75,476
....

b) 使用get_text()

for tag in cars:
    print(tag.get_text().strip())

c) 如果标签内只有那个字符串，你也可以使用这些选项

c) If there is only that string inside the tag, you can use these options also

• .string
• .contents[0]
• next(tag.children)
• next(tag.strings)
• next(tag.stripped_strings)

即.

for tag in cars:
    print(tag.string.strip()) #or uncomment any of the below lines
    #print(tag.contents[0].strip())
    #print(next(tag.children).strip())
    #print(next(tag.strings).strip())
    #print(next(tag.stripped_strings))

输出:

$71,996
$75,831
$71,412
$75,476
$77,001
...

注意:

.text 和 .string 不一样.如果标签中有其他元素，.string 返回 None，而 .text 将返回标签内的文本.

.text and .string are not the same. If there are other elements in the tag, .string returns the None, while .text will return the text inside the tag.

from bs4 import BeautifulSoup
html="""
<p>hello <b>there</b></p>
"""
soup = BeautifulSoup(html, 'html.parser')
p = soup.find('p')
print(p.string)
print(p.text)

输出

None
hello there
