What's in Your HTML Toolbox?

Milo_Mindbender asks: "I've just ended up in charge of cleaning up an old and rather large website created by some non technical people. It has all the usual problems: paragraph tags with no ending tag; mixed case file names that work on Windows but not on a Linux webserver; files with mixed Windows/Linux/Mac line endings; duplicates or partial duplicates of files created when working on pages; and the list goes on. I'm wondering what tools you guys keep in your HTML/website toolboxes that work good for cleaning up this sort of mess. Things like pretty-printers, HTML 'lint' programs, dead file detectors, batch renamers (that change links and the files they point to into OS neutral names), and 'diff' programs that ignore HTML whitespace. I'm particularly interested in batch processing tools that actually fix problems (not just report them) because I've got a lot of files to deal with and don't have the time to edit every one by hand. So what's in YOUR toolbox?"

So what's in YOUR toolbox?

CAPITAL ONE!

Wait, what was the question again?

MY toolbox...

[grammar fascist]

My toolbox has a little white pill that I take every time I get a hankering to work with HTML. It fixes me up right quick.

Actually... Frontpage

Actually... Frontpage.

No, really, stop laughing.

Frontpage, once you convince it to stop the WYSIWTG crap, has three tools that will make fixing a non-technical user's webpage easy. (Never, ever, let a non-technical user use Frontpage without supervision. It's worse than Word.)

1. "Site Management", where you can let Frontpage check for dead files, orphan files, broken links, and do mass re-names of all HTML-based links. (No script correction here, but non-techies don't do that.)
2. Regular Expresions (or a workable subset thereof)
3. VBA, to invoke things like "optimize HTML" and "standardize name"

I'd be shocked if there aren't better tools out there -- but by and large either they don't do as much, or they cost a significant chunk of change.

(Hey, you, with the laughing -- point me to a app that can do #1 with compatible replacements for #2 and #3, and, er, you'll get good karma for being so mean and laughing.)
