I have been assigned with the task of maintaining a specific Drupal site. The problem is that the person who created the website did not actually think it through. No input filters to be heard of, no restriction for images' placement, plain HTML everywhere.
I'm now on the spot, since I've promised to tidy up the website, and I've just realized how much work will it require. There are articles that are copy+pasted from wikipedia (the WYSIWYG editor kept all the formatting), random websites or (even worse) from MS Word.
I understand that I will have to do some manual editing and check the articles one by one, but I was wondering if there is some kind of a method that someone may have used in a similar situation. Perhaps a module that will cleanup the html of the various nodes?
Note: The website is built in Drupal 6, but if you have suggestions for Drupal 7, I guess that I could upgrade.
