Question

我正在尝试制作一个读取crunchyroll页面的python脚本，并给我字幕的ssid。

例如： - http://www.crunchyroll.com/i-cant-understand-what-my-husband-is-saying/episode-1-wriggling-memories-678035

转到源代码并查找ssid，我想在此元素的ssid之后提取数字

 <a href="/i-cant-understand-what-my-husband-is-saying/episode-1-wriggling-memories-678035?ssid=154757" title="English (US)">English (US)</a>

我想提取“154757”，但我似乎无法让我的脚本正常工作

这是我目前的剧本：

import feedparser
import re
import urllib2
from urllib2 import urlopen
from bs4 import BeautifulSoup


feed = feedparser.parse('http://www.crunchyroll.com/rss/anime')
url1 = feed['entries'][0]['link']
soup = BeautifulSoup(urlopen(url1), 'html.parser')

如何修改我的代码以搜索和提取该特定数字？

Answer 1

这可以让您开始为每个条目提取ssid。请注意，其中一些链接没有任何ssid因此您必须考虑到一些错误捕获。此处无需re或urllib2模块。

import feedparser
import requests
from bs4 import BeautifulSoup


d = feedparser.parse('http://www.crunchyroll.com/rss/anime')
for url in d.entries:
    #print url.link
    r = requests.get(url.link)
    soup = BeautifulSoup(r.text)
    #print soup
    subtitles = soup.find_all('span',{'class':'showmedia-subtitle-text'})
    for ssid in subtitles:
        x = ssid.findAll('a')
        for a in x:
            print a['href']

还有更多，但为了简洁，我把它们留了下来。从这些结果中，您应该能够轻松地解析ssid一些切片，因为它看起来像ssid都是6位数。做类似的事情：

print a['href'][-6:]

可以解决问题，让你 ssid。
