Firstly, I am a complete newbie when it comes to Python. However, I have written a piece of code to look at an RSS feed, open the link and extract the text from the article. This is what I have so far:
from BeautifulSoup import BeautifulSoup import feedparser import urllib # Dictionaries links = {} titles = {} # Variables n = 0 rss_url = "feed://www.gfsc.gg/_layouts/GFSC/GFSCRSSFeed.aspx?Division=ALL&Article=All&Title=News&Type=doc&List=%7b66fa9b18-776a-4e91-9f80- 30195001386c%7d%23%7b679e913e-6301-4bc4-9fd9-a788b926f565%7d%23%7b0e65f37f-1129-4c78-8f59-3db5f96409fd%7d%23%7bdd7c290d-5f17-43b7-b6fd-50089368e090%7d%23%7b4790a972-c55f-46a5-8020-396780eb8506%7d%23%7b6b67c085-7c25-458d-8a98-373e0ac71c52%7d%23%7be3b71b9c-30ce-47c0-8bfb-f3224e98b756%7d%23%7b25853d98-37d7-4ba2-83f9-78685f2070df%7d%23%7b14c41f90-c462-44cf-a773-878521aa007c%7d%23%7b7ceaf3bf-d501-4f60-a3e4-2af84d0e1528%7d%23%7baf17e955-96b7-49e9-ad8a-7ee0ac097f37%7d%23%7b3faca1d0-be40-445c-a577-c742c2d367a8%7d%23%7b6296a8d6-7cab-4609-b7f7-b6b7c3a264d6%7d%23%7b43e2b52d-e4f1-4628-84ad-0042d644deaf%7d" # Parse the RSS feed feed = feedparser.parse(rss_url) # view the entire feed, one entry at a time for post in feed.entries: # Create variables from posts link = post.link title = post.title # Add the link to the dictionary n += 1 links[n] = link for k,v in links.items(): # Open RSS feed page = urllib.urlopen(v).read() page = str(page) soup = BeautifulSoup(page) # Find all of the text between paragraph tags and strip out the html page = soup.find('p').getText() # Strip ampersand codes and WATCH: page = re.sub('&\w+;','',page) page = re.sub('WATCH:','',page) # Print Page print(page) print(" ") # To stop after 3rd article, just whilst testing ** to be removed ** if (k >= 3): break
This produces the following output:
>>> (executing lines 1 to 45 of "RSS_BeautifulSoup.py") Total deposits held with Guernsey banks at the end of June 2012 increased 2.1% in sterling terms by £2.1 billion from the end of March 2012 level of £101 billion, up to £103.1 billion. This is 9.4% lower than the same time a year ago. Total assets and liabilities increased by £2.9 billion to £131.2 billion representing a 2.3% increase over the quarter though this was 5.7% lower than the level a year ago. The higher figures reflected the effects both of volume and exchange rate factors. The net asset value of total funds under management and administration has increased over the quarter ended 30 June 2012 by £711 million (0.3%) to reach £270.8 billion.For the year since 30 June 2011, total net asset values decreased by £3.6 billion (1.3%).

The problem is that this is the first paragraph of each article, however I need to show the entire article. Any help would be gratefully received.
The navigablestring object is used to represent the contents of a tag. To access the contents, use “. string” with tag. You can replace the string with another string but you can't edit the existing string.
To get href with Python BeautifulSoup, we can use the find_all method. to create soup object with BeautifulSoup class called with the html string. Then we find the a elements with the href attribute returned by calling find_all with 'a' and href set to True .
You are getting close!
# Find all of the text between paragraph tags and strip out the html page = soup.find('p').getText()
Using find (as you've noticed) stops after finding one result. You need find_all if you want all the paragraphs. If the pages are formatted consistently ( just looked over one), you could also use something like
soup.find('div',{'id':'ctl00_PlaceHolderMain_RichHtmlField1__ControlWrapper_RichHtmlField'})
to zero in on the body of the article.
