I'm currently trying to learn HTML and Java EE Servlet programming. I have an application server running on my local machine (Orion Application Server) and I'm connecting to web pages I've deployed on this server using a browser running on the same machine, directed to http://localhost/mypage.htm (for example).
I know W3C has a site you can go to that will validate an HTML page (and count how many errors are found for a given doctype), but that has to be a publicly available URL. How do you validate HTML on a locally running setup like I've described above?
many options:
see installation of w3c validation service:
http://validator.w3.org/docs/install.html
Firefox addons:
Firefox addon or other tool to locally validate HTML pages
