You can parse the buffer, and run some code on all of the links. I did
something like this here
http://kitchingroup.cheme.cmu.edu/blog/2013/09/28/Changing-links-to-files-so-they-work-in-a-blog/for
another reason. You could adapt that to do your link validation. I
guess you will need to send a request to the url to see if it is valid.
