使用python 3在html标签之间提取文本

Question

我正在尝试抓取一个网站，我想提取在html标签之间输入的链接的标题（“高级行政官员在美中经济关系情况说明书上的新闻发布会”）。 我正在使用的HTML源代码如下：

<h3 class="field-content"><a href="https://www.whitehouse.gov/the-press- 
office/2013/12/05/press-briefing-senior-administration-officials-fact-sheet- 
strengthening-">Press Briefing by Senior Administration Officials on the Fact 
Sheet on Strengthening U.S.-China Economic Relations</a></h3>

我的程序代码如下：

import requests
from bs4 import BeautifulSoup

url = 'http://stash.compjour.org/samples/webpages/whitehouse-press-briefings-page-50.html'
resp = requests.get(url)
soup = BeautifulSoup(resp.text, 'lxml')

urls = []
for h in soup.find_all('h3'):
    a = h.find('a')
    urls.append(a.attrs['href'])
print(urls)

Answer 1

您可以使用.text属性获取标签中包含的文本。 我用str.rsplit从标题中删除日期：

import requests
from bs4 import BeautifulSoup

url = 'http://stash.compjour.org/samples/webpages/whitehouse-press-briefings-page-50.html'
resp = requests.get(url)
soup = BeautifulSoup(resp.text, 'lxml')

for a in soup.select('h3 a[href]'):
    print(a.text.rsplit(',', maxsplit=1)[0])
    print(a['href'])
    print('-' * 80)

打印：
