collect text from web pages of a given site
<p>There is a site that I frequenly visit and read the "best advice". Here is how I can easily extract the text that I want...</p>

<pre><code>import urllib2
from bs4 import BeautifulSoup  

mylist=list()

myurl='http://www.apartmenttherapy.com/carols-east-side-cottage-house-tour-194787'
s=urllib2.urlopen(myurl)
soup =  BeautifulSoup(s)

hello = soup.find(text='Best Advice: ')
mylist.append(hello.next)
</code></pre>

<p>But how do I collect the text snippets from all the pages?</p>

<hr>

<p>I can search for all pages using this simple google query...</p>

<p>site:<a href="http://www.apartmenttherapy.com" rel="nofollow">http://www.apartmenttherapy.com</a></p>

<p>Does google search has API that can be used in python?
I am looking for one time simple solution for this problem. So I will prefer not to install too many packages to get this task done.</p>

<p>You may read the <a href="https://www.crummy.com/software/BeautifulSoup/bs4/doc/" rel="nofollow">BeautifulSoup</a> manual first and also learn to use web developper tool to inspect network flow.</p>

<p>Once done, you may see that you can get the list of house with a GET request <a href="http://www.apartmenttherapy.com/search?page=1&amp;q=House+Tour&amp;type=all" rel="nofollow">http://www.apartmenttherapy.com/search?page=1&amp;q=House+Tour&amp;type=all</a> </p>

<p>Assuming that, we can iterate from page 1 to X to get all houses index page.</p>

<p>On each index page you get exactly 15 urls to add to a list.</p>

<p>Once you got the complete urls list, you may scrap each url to get "best advice" text on each of them.</p>

<p>Please see the following code which do the job :</p>

<pre><code>import time
import requests
import random
from bs4 import BeautifulSoup  

#here we get a list of all url to scrap
url_list=[]
max_index=2 

for page_index in range(1,max_index):

    #get index page
    html=requests.get("http://www.apartmenttherapy.com/search?page="+str(page_index)+"&amp;q=House+Tour&amp;type=all").content

    #iterate over teaser
    for teaser in BeautifulSoup(html).findAll('a',{'class':'SimpleTeaser'}):

        #add link to url list
        url_list.append(teaser['href'])

    #sleep a litte to avoid overload/ to be smart
    time.sleep(random.random()/2.) # respect server side load

    #here I break because it s just an example (it does not required to scrap all index page)
    break #comment this break in production


#here we show list  
print url_list


#we iterate over url to get the advice
mylist=[]
for url in url_list:

    #get teaser page
    html=requests.get(url).content

    #find best advice text
    hello = BeautifulSoup(html).find(text='Best Advice: ')

    #print advice
    print "advice for",url,"\n","=&gt;",

    #try to add next text to mylist
    try:
        mylist.append(hello.next)
    except:
        pass

    #sleep a litte to avoid overload/ to be smart
    time.sleep(random.random()/2.) # respect server side load

#show list of advice
print mylist
