[Wikitech-l] Help needed with extension

Dear All,

I am new to developing extensions for mediawiki and need your guidance with a particular extension I am working on for my research. Basically, I want to color the words in an article based on its age. As a first step, I am writing a simple extension which just colors all words in an article. I am having problems with the hook I need to use.

I use the 'OutputPageBeforeHTML' hook to add span tags to the text before it is actually displayed. But that does not seem to be working. So I have 2 questions.

1. Which hook would be the right one to add span tags to every word in an article. 2. How do i extract the words in an article, without the markup details?

Any help would be appreciated.

Thanks
