ExtractValue didn't understand tag and attribute names consisting of "tricky" national letters (e.g. latin accenter letters). It happened because XPath lex parser recognized only basic latin letter a..z ad a part of an identifier. Fixed to recognize all letters by means of new "full ctype" which was added recently.
