Question

我无法解析youtube播放列表的HTML。例如，当我检查“ https://www.youtube.com/playlist?list=PLS1QulWo1RIYmaxcEqw5JhK3b-6rgdWO_”的标签时。我看到了类名“ yt-simple-endpoint.style-scope.ytd-playlist-video-renderer ”。但这在我使用bs4选择元素时不起作用。但是，我在网上找到了另一段工作代码，该代码选择了以下类别“ pl-video-title-link ”。但是我无法在网页上找到此类，并且所有标签都没有此类？随附的是工作代码。任何帮助将不胜感激。

from bs4 import BeautifulSoup as bs
import requests
r = requests.get('https://www.youtube.com/playlist? 
list=PLS1QulWo1RIYmaxcEqw5JhK3b-6rgdWO_')
page = r.text
soup = bs(page,'html.parser')
res = soup.find_all('a',{'class':'pl-video-title-link'})
for l in res:
print (l.get("href"))

Answer 1

此页面使用JavaScript更改了其结构，但是您可以在下载时打印汤，然后查看视频链接的初始位置。在这种情况下，请在标签redirectPath中使用类<tr>：

pl-video

打印：

from bs4 import BeautifulSoup
import requests

url = 'https://www.youtube.com/playlist?list=PLS1QulWo1RIYmaxcEqw5JhK3b-6rgdWO_'
page = requests.get(url)
soup = BeautifulSoup(page.text, 'lxml')

for i, tr in enumerate(soup.select('tr.pl-video')):
    print('{}. {}'.format(i + 1, tr['data-title']))
    print('https://www.youtube.com' + tr.a['href'])
    print('-' * 80)
