Use the "(?s)" directive:

on mouseUp
  local tTitle
  put "<title>some title"&cr&"</title>" into tXML
  get matchText(tXML,"(?s)title>(.*?)</title",tTItle)
  put tTitle
end mouseUp

Note that you'll get the trailing CR after "some title" as well, so you'd
have to strip that out if you want to.

Check the docs at http://www.prce.org/man.txt - the "?s" directive
corresponts to PCRE_DOTALL, which causes the "." character to match all
characters, including newlines (CRs).
