使用feedparser访问重复的提要标记

Question

我正在尝试分析此提要：https://feeds.podcastmirror.com/dudesanddadspodcast

channel部分有两个podcast:person条目

<podcast:person role="host" img="https://dudesanddadspodcast.com/files/2019/03/andy.jpg" href="https://www.podchaser.com/creators/andy-lehman-107aRuVQLA">Andy Lehman</podcast:person>
<podcast:person role="host" img="https://dudesanddadspodcast.com/files/2019/03/joel.jpg" href="https://www.podchaser.com/creators/joel-demott-107aRuVQLH" >Joel DeMott</podcast:person>

解析时，feedparser只引入一个名称

> import feedparser
> d = feedparser.parse('https://feeds.podcastmirror.com/dudesanddadspodcast')
> d.feed['podcast_person']
> {'role': 'host', 'img': 'https://dudesanddadspodcast.com/files/2019/03/joel.jpg', 'href': 'https://www.podchaser.com/creators/joel-demott-107aRuVQLH'}

我会改变什么，这样它就会显示一个podcast_person的列表，这样我就可以遍历每个列表了

Answer 1

与feedparser相比，我更喜欢BeautifulSoup

您可以复制以下代码来测试最终结果

from bs4 import BeautifulSoup
import requests

r = requests.get("https://feeds.podcastmirror.com/dudesanddadspodcast").content
soup = BeautifulSoup(r, 'html.parser')

feeds = soup.find_all("podcast:person")

print(type(feeds))  # <list>

# You can loop the `feeds` variable.

Answer 2

想法#1:

from bs4 import BeautifulSoup
import requests

r = requests.get("https://feeds.podcastmirror.com/dudesanddadspodcast").content
soup = BeautifulSoup(r, 'html.parser')

soup.find_all("podcast:person")

输出：

[<podcast:person href="https://www.podchaser.com/creators/andy-lehman-107aRuVQLA" img="https://dudesanddadspodcast.com/files/2019/03/andy.jpg" role="host">Andy Lehman</podcast:person>,
 <podcast:person href="https://www.podchaser.com/creators/joel-demott-107aRuVQLH" img="https://dudesanddadspodcast.com/files/2019/03/joel.jpg" role="host">Joel DeMott</podcast:person>,
 <podcast:person href="https://www.podchaser.com/creators/cory-martin-107aRwmCuu" img="" role="guest">Cory Martin</podcast:person>,
 <podcast:person href="https://www.podchaser.com/creators/julie-lehman-107aRuVQPL" img="" role="guest">Julie Lehman</podcast:person>]

---

创意#2:

导入feedparser

d = feedparser.parse('https://feeds.podcastmirror.com/dudesanddadspodcast')
hosts = d.entries[1]['authors'][1]['name'].split(", ")

print("The hosts of this Podcast are {} and {}.".format(hosts[0], hosts[1]))

输出：

The hosts of this Podcast are Joel DeMott and Andy Lehman.

Answer 3

您可以迭代feed['items']并获取所有记录

import feedparser

feed = feedparser.parse('https://feeds.podcastmirror.com/dudesanddadspodcast')

if feed:
    for item in feed['items']:
        print(f'{item["title"]} - {item["author"]}')
