in thread XMLin question

I'm not surprised. \K was added in perl 5.10 but with -e perl won't use any features that are so "recent". Try "-E" instead, at least, if you have perl 5.10 or later.

But, I don't think it will work, anyway. /([><])([^\w])/ would fix every "</" in your XML, and that just isn't right.
