使用Python从HTML文件中提取文本（音乐艺术家/标题）

我想从一个页面上提取艺术家和歌曲的标题

页面：

不是我的儿子
起源

这在页面上重复了几次（请参见顶部链接swr3.de），但我不知道如何使用beautifulsoup和python创建列表，如：

创世纪-没有我的儿子
加倍你-请不要走

使用、和的组合：

首先，安装先决条件：

pip install beautifulsoup4
pip install requests
pip install lxml

import requests, lxml
from bs4 import BeautifulSoup

parsedsongs = []
result = requests.get('http://www.swr3.de//-/id=47424/cf=42/did=65794/93avs/index.html?hour=5&date=2015-10-23')
soup = BeautifulSoup(result.content, "lxml")
detailbodys = soup.find_all('div', 'detail-body')
for detailbody in detailbodys:
    title = detailbody.h4.string.encode('utf-8').strip()
    if detailbody.h5:
        artist = detailbody.h5.string.encode('utf-8').strip()
    else:
        artist = detailbody.span.string.encode('utf-8').strip()
    parsedsongs.append({'artist': artist, 'title': title})

for entry in parsedsongs:
    print 'Artist: {}\tTitle: {}'.format(entry['artist'], entry['title'])

(swr3)macbook:swr3 joeyoung$ python swr3.py
Artist: Vaya Con Dios   Title: Nah neh nah

Artist: Genesis Title: No son of mine
Artist: Double You  Title: Please don't go

    else:
