innerXML = do
          x <- (try xml <|> gettext)
          return x
Omit "try" (and return).
xml always starts with "<" whereas gettext never does.
I was wrong, you do not want to swallow an endTag as openTag.
openTag should start with:
     try $ char '<' >> notFollowedBy (char '/')
and endTag should start with:
         try $ string "
Strictly, the try in endTag is not necessary (only in openTag)
