html5lib

I'm a very newbie webpage builder, currently working on creating a website that needs to change link colours according to the destination page. The links will be sorted into different classes (e.g. good, bad, neutral) by certain user input criteria-- e.g. links with content the user would find of interest is colored blue, stuff that the user (presumably) doesn't want to see is colored as normal text, etc.

I reckon I need a way to parse the webpage for links to the content (stored in MySQL database), change the colors for all the links on the page (so I need to be able to change the link classes in the HTML as well) before outputting the adapted page to the user. I read that regex is not a good way to find those links-- so should I use a library, and if so, is html5lib good for what I'm doing?
