BeautifulSoup网站scraping - html解析

Question

我正在尝试使用beautifulsoup4从网站中抓取数据，并且只检索html标记之间的信息以放入excel文档，目前我只能从页面中获取整个html数据。

import sys
import urllib3
import xlsxwriter
import lxml

page = requests.get('genericurlhere.com')
soup = BeautifulSoup(page.text, 'html.parser')

f = csv.writer(open('web_scrape.csv', 'w'))
f.writerow(['Item', 'Description'])


heading = soup.find_all("h4", class_="list-group-item-heading")
print(heading)
print('-------------------')
desc = soup.find_all("p", class_='list-group-item-text')
print(desc)

Answer 1

尝试使用text

desc = soup.find_all("p", class_='list-group-item-text')
desc = [e.text for e in desc] # only text within tags from the html elements.
print(desc)

请注意，还可以使用[]获取html标记的属性，如：each['id']。
