Articles database and managing interface(repost)

Hi guys! I want to make a database storing a selection of web-published articles (either at my site or in print), but I want to be able to change the original publishing stylesheet for readability purposes. Moreover, I would like to have only the body of the article, without all the other columns that the newspaper presents on its site. Here is a typical article of the specific newspaper as it has been originally published: [login to view URL] As you can see there is a menu on the left, another on the right, header and a banner at the top and a complicated table containing the article in the middle. I want to strip all these and get just the article, but with my own preferences in the properties of the style sheet. Legal: My organization holds full responsibility of presenting a clear reference to the source, which is perfectly legal in this case. Moreover, it is part of this project to make a custom label, that will be attached to each article, containing the name of the newspaper, the publishing date, section, subsection, author, original title and a brief description of category, that I will be assigning to each article.
