使用 beutifulsoup 和 mechanize 从 html 表获取文本时出错

Question

我试图从表格标签内的 html 代码中获取文本，但我没有得到所有文本。相反，我得到了一些部分文本，其余的被忽略了

这是我的输出和代码：

输出

Public Sector Organization (Recruitment Test)
Test held on: Saturday, 3rd & Sunday 4th, December 2016
>>> 

代码

import mechanize
from bs4 import BeautifulSoup
import urllib
from PIL import Image
import os


Roll=60170001          

url = "http://nts.org.pk/Test&Products/Results/012017/PubSecOrg_24122016_Result/Search.php"

br = mechanize.Browser()
br.set_handle_robots(False) # ignore robots
br.open(url)
br.select_form(nr=0)                                                            
rollnumber=str(Roll)
captcha=11111
cap=str(captcha)                        
br["RollNo"]=rollnumber
br["captcha"]=cap
res = br.submit()
content = res.read()
soup = BeautifulSoup(content,"html.parser")
rolln=soup('table')[2]
rolln=rolln.text.encode('utf-8')
print rolln

Answer 1

这种方法似乎可以满足您的需求。

>>> content = open(r"C:\scratch\___National Testing Service___.html").read()
>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(content, 'lxml')
>>> tables = soup.findAll('table')
>>> len(tables)
8
>>> tables[2].text

假设mechanize 为您提供的文件格式与我只需在 Chrome 浏览器中打开页面并保存即可获得的格式相同。
