beautifulsoup find_all 标题

Question

html是

<div class="trn-defstat__value">
    <img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-ash.16913d82e3.png" title="ASH" style="height:    35px; padding-right: 8px;"> 
    <img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-jager.600b2773be.png" title="JÄGER"   style="height: 35px; padding-right: 8px;">
    <img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-bandit.385144d970.png" title="BANDIT"     style="height: 35px; padding-right: 8px;">
</div>

我想获取每个 title 的值。

但在那之前，我是这样写的

from bs4 import BeautifulSoup as bs
import requests


bsURL = "https://r6.tracker.network/profile/pc/Spoit.GODSENT"
respinse = requests.get(bsURL)
html = bs(respinse.text, 'html.parser')


title = html.find_all(class_='trn-defstat__value')[4]

print(title)

结果->

<div class="trn-defstat__value">
<img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-ash.16913d82e3.png" style="height: 35px; padding-right: 8px;" title="ASH"/>
<img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-jager.600b2773be.png" style="height: 35px; padding-right: 8px;" title="JÄGER"/>
<img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-bandit.385144d970.png" style="height: 35px; padding-right: 8px;" title="BANDIT"/>
</div>

我该怎么办？

Answer 1

此脚本将打印 Top Operators 部分中的所有 <img> 标题：

from bs4 import BeautifulSoup as bs
import requests


bsURL = "https://r6.tracker.network/profile/pc/Spoit.GODSENT"
respinse = requests.get(bsURL)
html = bs(respinse.text, 'html.parser')

# find Top Operators tag
operators = html.find(class_='trn-defstat__name', text='Top Operators')

for img in operators.find_next('div').find_all('img'):
    print(img['title'])

打印：

ASH
JÄGER
BANDIT

---

或者使用 CSS：

for img in html.select('.trn-defstat__name:contains("Top Operators") + * img'):
    print(img['title'])

Answer 2

只需使用.get()函数获取属性并传入属性名称即可。

pip install html5lib

我建议你使用它，我相信它是一个更好的解析器。

from bs4 import BeautifulSoup as bs 
import requests   
bsURL = "https://r6.tracker.network/profile/pc/Spoit.GODSENT" 

respinse = requests.get(bsURL) 



html = bs(respinse.content, 'html5lib')   


container = html.find("div", class_= "trn-defstat mb0 top-operators")


imgs = container.find_all("img")


for img in imgs:
     print(img.get("title"))

我似乎不明白您试图抓取网站的哪个部分，但请注意有时会首先获取 html 代码的 block，其中有您想要抓取的详细信息 :)

Answer 3

这应该对你有帮助：

from bs4 import BeautifulSoup

html = """
<div class="trn-defstat__value">
    <img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-ash.16913d82e3.png" title="ASH" style="height:    35px; padding-right: 8px;"> 
    <img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-jager.600b2773be.png" title="JÄGER"   style="height: 35px; padding-right: 8px;">
    <img src="https://trackercdn.com/rainbow6-ubi/assets/images/badge-bandit.385144d970.png" title="BANDIT"     style="height: 35px; padding-right: 8px;">
</div>
"""
soup = BeautifulSoup(html,'html.parser')

imgs = soup.find_all('img')

for img in imgs:
    print(img['title'])

输出：

ASH
JÄGER
BANDIT

完整代码如下：

from bs4 import BeautifulSoup as bs
import requests

bsURL = "https://r6.tracker.network/profile/pc/Spoit.GODSENT"
respinse = requests.get(bsURL)
html = bs(respinse.text, 'html.parser')
divs = html.find_all('div',class_ = "trn-defstat__value")
imgs = []
for div in divs:
    try:
        imgs.append(div.find_all('img'))
    except:
        pass

imgs = [ele for ele in imgs if ele != []]
imgs = [j for sub in imgs for j in sub]

for img in imgs:
    print(img['title'])

输出：

ASH
JÄGER
BANDIT
