How does one validate an entire site?

Question

I realize there's the W3C validator, which works great for one page. There's also the perl install they provide, but it seems to not work on a Mac or it's buggy.

Given that

1) I have an entire set of local files

How do I

a) Validate the entire set

b) do it behind a firewall

c) do it simply without installing anything on my computer? (i.e., is there a web service?)

Or is this just futile?

Answer 1

There are some sites that can do batch validation, like WDG HTML Validator, so that you can validate multiple pages at once, but I believe it is only for html. I don't know if there are similar validators for other languages. I will keep looking to see what else I can find

I also found a link to use w3c validator for batch validation Here

EDIT*

You could also use something like dreamweaver in xhtml format, but I find it doesn't do a very good job of it.
