如何使用beautifulsoup python在HTML列表中提取文本 [英] How to extract text within HTML lists using beautifulsoup python

问题描述

我正在尝试编写一个python程序，该程序可以在html中的列表之间提取文本.我想提取诸如精装书和页数之类的信息.有人知道此操作的命令吗?

I'm trying to write a python program that can extract text between list in html. I would like to extract information like the book being hardcover and number of pages. Does anybody know the command for this operation?

<h2>Product Details</h2>
  <div class="content">
<ul>

<li><b>Hardcover:</b> 156 pages</li>

<li><b>Publisher:</b> Insight Editions; Har/Pstr edition (June 18, 2013)</li>

<li><b>Language:</b> English</li>

<li><b>ISBN-10:</b> 1608871827</li>
<li><b>ISBN-13:</b> 978-1608871827</li>

要解析我使用的其他信息:

For parse other information I used:

definition in soup.findAll('span', {"class":'bb_price'}):
definition = definition.renderContents() 

但不适用于这种情况.

推荐答案

通过工作示例:

from bs4 import BeautifulSoup

data = """<h2>Product Details</h2>
  <div class="content">
<ul>

<li><b>Hardcover:</b> 156 pages</li>

<li><b>Publisher:</b> Insight Editions; Har/Pstr edition (June 18, 2013)</li>

<li><b>Language:</b> English</li>

<li><b>ISBN-10:</b> 1608871827</li>
<li><b>ISBN-13:</b> 978-1608871827</li></ul></div>"""

soup = BeautifulSoup(data)

print soup.find('b', text='Hardcover:').next_sibling
print soup.find('b', text='Publisher:').next_sibling

打印:

156 pages
