Parsing multiple News articles
Your solution is really going to be specific to each website page you want to scrape, so, without knowing the websites of interest, the only thing I could really suggest would be to inspect the page source of each page you want to scrape and look if the article is contained in some html element with a specific attribute (either a unique class, id, or even summary attribute) and then use beautiful soup to get the inner html text from that element
I have built a program for summarization that utilizes a parser to parse from multiple websites at a time. I extract only <p> in each article. 
This throws out a lot of random content that is unrelated to the article. I've seen several people who can parse any article perfectly. How can i do it? I am using Beautiful Soup
