Hello,
It's a great feature but not really something that you'd expect an "HTML Validator" to do. However, the
CSE HTML Validator's Editor does have a "Search->Replace in All Open Documents" feature you may want to try.
I also used the
HomeSite search and replace feature in the past, but it seemed problematic on Vista/Windows 7.
I recommend a program called
Replace Text here:
http://www.htmlvalidator.com/htmlval/resources.htmlYou may want to try it. I think I've run into some issues with it (like locking up/freezing) but have had successes as well. It does warn about "known problems with some Windows 7 installations", whatever that means. It also can be a bit complicated to use at first, but seems like it is fairly powerful.
If anyone else can recommend a better/more reliable standalone search & replace program, then I'd like to find one.
UPDATE: if you just need to search, you may want to try "findstr" on Windows. That's what I use when programming and I want to search my source code files for something.
