在 BeautifulSoup python 中搜索特定字词

Question

我正在尝试制作一个 python 脚本来读取 crunchyroll 的页面并为我提供字幕的 ssid。

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

去源码里找ssid，我想提取这个元素ssid后面的数字

 <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”，但我的脚本似乎无法运行

这是我当前的脚本：

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号码？

Answer 1

这应该让您开始能够为每个条目提取 ssid。请注意，其中一些 link 没有任何 ssid 因此您必须考虑到一些错误捕获。这里不需要 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']

输出：

还有更多，但为简洁起见，我将它们排除在外。从这些结果中，您应该能够通过一些切片轻松地解析出 ssid，因为看起来 ssid 都是 6 位数字长。做类似的事情：

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

会成功，让你只是 ssid。
