App for cleaning offline articles.

I have a lot of news articles that i've saved to my hard disc. I need something to... 1) clean them down to only keeping the 1a: main text itself 1b: author 1c: date published 1d: source newspaper Thus removing all scripts and stuff) See attached examples of original and cleaned article. 2) i also need it to find the source on the internet, so it finds and adds the web location of the text. Perhaps this can sometimes find the source newspaper. I want to keep the "one article in one file" (so it should be an option to just save with the same file name) but how does one then add info to it? Perhaps adding the source web link? Or should it be a database???? How can this be done? What would it cost?
