Python BeautifulSoup 刮表 [英] Python BeautifulSoup scrape tables

问题描述

我正在尝试使用 BeautifulSoup 创建一个表格.我写了这个 Python 代码:

I am trying to create a table scrape with BeautifulSoup. I wrote this Python code:

import urllib2
from bs4 import BeautifulSoup

url = "http://dofollow.netsons.org/table1.htm"  # change to whatever your url is

page = urllib2.urlopen(url).read()
soup = BeautifulSoup(page)

for i in soup.find_all('form'):
    print i.attrs['class']

我需要抓取 Nome、Cognome、Email.

I need to scrape Nome, Cognome, Email.

推荐答案

Loop over table rows (tr tag) 并获取里面的单元格的文本 (td tag):

Loop over table rows (tr tag) and get the text of cells (td tag) inside:

for tr in soup.find_all('tr')[2:]:
    tds = tr.find_all('td')
    print "Nome: %s, Cognome: %s, Email: %s" % 
          (tds[0].text, tds[1].text, tds[2].text)

印刷品:

Nome:  Massimo, Cognome:  Allegri, Email:  [e-mail]
Nome:  Alessandra, Cognome:  Anastasia, Email:  [e-mail]
...

仅供参考，[2:] 这里的切片是跳过两个标题行.

FYI, [2:] slice here is to skip two header rows.

UPD，以下是将结果保存到 txt 文件的方法:

UPD, here's how you can save results into txt file:

with open('output.txt', 'w') as f:
    for tr in soup.find_all('tr')[2:]:
        tds = tr.find_all('td')
        f.write("Nome: %s, Cognome: %s, Email: %s
" % 
              (tds[0].text, tds[1].text, tds[2].text))
