Python Beautifulsoup。解析<p></p>

Question

我正在学习如何解析Beautifulsoup。有人能解释我如何解析div class="article-content"中的<p></p>元素。我希望在脚本启动后只能看到内容信息。让我证明我想要的东西：

我可以在<p></p>解析div class="article-content"，但不能所需的信息。我的代码看起来这样的方式：

import urllib2 
from bs4 import BeautifulSoup 

html = urllib2.urlopen('http://www.engadget.com/2014/10/17/local-multiplayer-is-coming-to-android-games/') 
parsed_html = BeautifulSoup(html) 
print parsed_html.body.find('div', attrs={'class':'article-content'}).text 

，但我得到也有很多垃圾：

$ python engadget_parser.py 


Ever wish that you could just whip out your Android device and harass a passer-by to play games with you? It's the sort of thing that Nintendo DS users, for example, have been using thanks to that company's StreetPass feature, but, until now, hasn't been available on Google's smartphones. Now, however, the company has an added an update to its games infrastructure that enables "ambient, real-time" games with more than one user - so long that the game relies upon Google's home-grown multiplayer backend. Still, maybe don't sprint into the street and start challenging people to a dual, because they might get the wrong idea. 





     onBreak({ 
      0: function(){ 
       (function() { 
         var a = { 
           mobilePlacementID: "348-14-15-135b", 
         width: "320", 
         height: "115" 
         }; 
        madserver.requestAd(a); 
       })(); 
      }, 
      768: function(){} 
     });

我喜欢在这种情况下美丽的选择方法。替换此：

print parsed_html.body.find('div', attrs={'class':'article-content'}).text 

有了这个：

for p in parsed_html.select('div.article-content p'): 
    print p.text

也许这是非常糟糕的代码，但无论如何，我会告诉他，不要捅我，我只是初学者在Python：

import urllib2 
from bs4 import BeautifulSoup 

url = "http://www.engadget.com/2014/10/17/castar-augmented-reality/" 

html = urllib2.urlopen(url) 
parsed_html = BeautifulSoup(html) 


def news_parser(url): 
    list = [] 
    for p in parsed_html.select('div.article-content p'): 
     list.append(p.text) 
    return list 


def longest_text_position(list): 
    # sometimes article is not in list[1] position, so I am searching a longest element in list 
    a = 0 
    longest_text = "" 

    for item in list: 
     x = len(item) 
     if x > a: 
      a = x 
      longest_text = item 

    position = list.index(longest_text) 
    return position 


def print_news(position): 
    print "-" * 80 
    print parsed_html.title.string 
    print "-" * 80 
    print list[position] 
    print "-" * 80 
    print " " 

list = news_parser(url) 
position = longest_text_position(list) 
print_news(position) 

结果如下：

$ python engadget_parser_new.py 
-------------------------------------------------------------------------------- 
castAR bets big on its augmented reality hardware with move to Silicon Valley 
-------------------------------------------------------------------------------- 
And they certainly were. From just a brief hands-on with the new hardware, I could tell the make out ....ating that I could look around objects by just walking around the table. Henkel-Wallace mentioned a potential for a holodeck application by blanketing a room with that retroreflective material, and I could certainly see a use case for that.
