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?"
