Yes, but that html has no "hidden" reference as in some
form of "href".

I see that I left off the leading `"` - but that would
still leave the problem of finding the extension
embedded in some text (false positive).

Better would be:

   "http://[^"]*\.(?:scr|exe|etc)"

Note: the use of the negative class obviates the need
to specify DOTALL.
