获得从HTML页面数据成Python阵列

Question

我只是试图从这样一个网页得到一些数据：

[ . . . ] 

<p class="special-large">Lorem Ipsum 01</p> 
<p class="special-large">Lorem Ipsum 02</p> 
<p class="special-large">Lorem Ipsum 03</p> 
<p class="special-large">Lorem Ipsum 04</p> 
<p class="special-large">Lorem Ipsum 05</p> 

[ . . . ] 

我想有一个python阵列类似以下：

myArrayWebPage = ["Lorem Ipsum 01","Lorem Ipsum 02","Lorem Ipsum 03","Lorem Ipsum 04","Lorem Ipsum 05"] 

这是我的Python脚本：

import urllib.request 

urlAddress = "http:// ... /" # my url address 
getPage = urllib.request.urlopen(urlAddress) 
outputPage = getPage.read() 
print(outputPage) 

我怎样才能从 “outputPage” 的阵列？

Answer 1

这似乎做你想要什么：

Python 3.6.0 (v3.6.0:41df79263a11, Dec 23 2016, 08:06:12) [MSC v.1900 64 bit (AMD64)] on win32 
Type "copyright", "credits" or "license()" for more information. 
>>> html = '''<p class="special-large">Lorem Ipsum 01</p> 
<p class="special-large">Lorem Ipsum 02</p> 
<p class="special-large">Lorem Ipsum 03</p> 
<p class="special-large">Lorem Ipsum 04</p> 
<p class="special-large">Lorem Ipsum 05</p>''' 
>>> import re 
>>> re.findall('<p class="special-large">([^<]+)</p>', html) 
['Lorem Ipsum 01', 'Lorem Ipsum 02', 'Lorem Ipsum 03', 'Lorem Ipsum 04', 'Lorem Ipsum 05'] 
>>> 

请注意，regular expressions通常不优选这样的事情。您应该使用类似Beautiful Soup的库。
