Let's say you're correcting a 200 line HTML file, currently open in your text editor, to make it look neater. E.g. fixing tags like < p id='some_id'> It would be ideal to use regular expression find and replace to look for: < ([a-z]) and replace with: <$1 Of course, be sure to review every replacement to make sure it isn't part of javascript or something like that. IMO it'd be faster than writing a script and then running it against the file.
